Auto changeover is available if the thermostat is configured for at least 1 Heat stage and 1 Cool stage, and ISU 3000 is set to “Auto”.

When configured this way, you can select “Auto” as one of the options under “System mode”.

ISU 3015 is the auto changeover differential setting. It can be set from 0-5 °F (0-2.5 °C). When in auto mode, the customer can always set the Heat and Cool set point to the same temperature, regardless of the differential setting although most customer prefer to have a cool set point that is at least 3 degrees above the Heat set point. When 0 is selected, we enforce a 1.5°F differential behind the scenes to ensure the heat doesn’t come on after cooling shuts off or vice-versa.

The differential is the minimum number of degrees the temperature needs to rise or fall before switching from Heat to Cool while in auto changeover mode. Example: With a differential of 3, if heat and cool were both set for 70, and heat had been used last, the temperature would need to rise at least 3 degrees above the heat set point before the thermostat would turn on cooling. Then it would run cooling down to set point and cycle cooling on and off to maintain set point. The temperature would then need to drop at least 3 degrees below the cool set point before heat could come on.

If the AC is used for dehumidification then we enforce an additional temp drop below the over-cooling amount, (ISU 9070) prior to switching back to heat.

Auxiliary Heat:

Auxiliary Heat runs as backup to the heat pump. It runs with the heat pump when:

• The thermostat is set to Heat mode.

• The Backup Heat is set to electric (ISU 2180).

• Load conditions determine Backup Heat is needed.

The heat pump could be locked out when in Heat mode by the balance point setting (ISU 3120) or if the backup heat is gas or oil and backup heat differential (ISU 3090) or upstage timer (ISU 3110) are used.

Emergency Heat:

Emergency Heat runs when you manually switch the thermostat to the Em Heat mode. When the thermostat is in Emergency Heat mode, the heat pump is locked out.

Emergency Heat mode is only available when the thermostat is set to control a heat pump or PTAC plus one or more Backup Heat stages.

From the home screen touch Mode. You can set the thermostat to Heat, Off, Cool, Emergency Heat, or Auto. (Auto mode may not be available based on installer settings.)

When the thermostat is set to Em Heat mode, the heat pump is locked out and the Backup Heat is used to maintain the heat set point.

If ISU 2175 is set to “Drive aux and E together”, then with a call for emergency heat or auxiliary heat, both E and AUX terminals are energized. Typically the backup heat is wired to Aux and E is unused when set this way. ISU 2175 is only available when there is a single auxiliary heat stage.

If ISU 2175 is set to “Aux and E independent”, then with a call for emergency heat, the E terminal is energized and the Aux terminal is not. The wire to Aux controls a heat source that runs as backup heat to the heat pump when the mode is set to “Heat”. The wire to E controls a heat source that runs independent of the heat pump when mode is set to Em Heat. In most cases, the heat pump uses the same heat source for auxiliary heat and em heat.

Dual fuel systems (Heat pump with gas or oil furnace backup) cannot run the heat pump and furnace at the same time or it can damage the coil. If the thermostat is set for "Thermostat controls backup heat" in ISU 2190 then the thermostat will never run the heat pump and furnace together. If 2190 is set to "External Fossil Fuel Kit Controls Backup Heat" then the thermostat may energize the heat pump and backup at the same time, when load conditions are high and the external fossil fuel kit will ensure that it locks out the heat pump when it runs the furnace.

Over time, the thermostat learns how long it takes your system to reach your programmed temperature setting.

The thermostat turns on the heating/cooling system early and assures that the programmed temperature setting is reached at the programmed time regardless of weather conditions. For example, if the Wake program period is set to 6:00 am with a heat setting of 70 degrees, the heat will turn on before 6:00 am, so the temperature is 70 degrees at 6:00 am. The thermostat displays "In Recovery” above the indoor temperature when it turns the system on early.

Adaptive Recovery calculates the recovery ramp based on how far the room temperature is away from the temperature setting, previous equipment performance and weather history, allowing the thermostat to start recovery at the optimal time so it can reach the programmed temperature setting at the programmed time. The thermostat uses two recovery ramps when set up to control a heat pump system; one ramp for the compressor and one ramp for the auxiliary heat. Once the room temperature intersects the compressor ramp, the compressor turns on until the set point is reached. If the room temperature does not rise quickly enough and intersects the second ramp, the auxiliary heat turns on. It takes about one week for the thermostat to adjust to weather conditions, equipment performance and construction of the home. If the temperature setting is reached too early or too late, the ramp is adjusted for the next day's recovery. See figure below:

If you prefer not to use this feature, touch Menu > Preferences > Adaptive Recovery and select Off. Then the thermostat will not start heating or cooling in advance of the comfort schedule time.

“Feels Like Temperature” is a setting which takes the indoor relative humidity into account so that you can optimize comfort. For example, when the relative humidity is very high, 70°F feels much warmer than it does when the relative humidity is very low. For this reason, when Feels Like Temperature is enabled, the display may show a warmer temperature reading than other thermostats do when relative humidity is high.

If you prefer not to use this feature, it can be disabled in Menu > Preferences > Display > Feels Like Temperature.

The thermostat keeps the compressor off for a few minutes before restarting, to prevent equipment damage. During this “off” time, the message "Waiting for equipment" is displayed on screen.

A conventional mechanical or electronic thermostat does not control temperature precisely at set point. Typically there is an offset (Differential) in the control point as the system load changes. Many factors contribute to offset including the switch differential, thermal lag, overshoot, cycle rates and system load.

The ElitePRO™ Series Thermostat however, works much differently than a conventional mechanical or electronic thermostat when Differential is set to comfort. Differential is always set to comfort and not adjustable when controlling a 2 stage furnace or 2 stage heat pump without Aux Heat. The proprietary algorithm in the thermostat eliminates the factors causing offset (Differential). This makes temperature control more accurate than the conventional mechanical or electronic thermostat. The temperature control algorithm is called proportional plus integral (P + I) control.

The thermostat sensor or indoor sensor senses the current space temperature. The proportional error is calculated by comparing the sensed temperature to the set point temperature. The deviation from the set point is the proportional error.

The thermostat also determines integral error, which is a deviation based on the length of error time (how long the sensed room temperature has been away from the set point temperature). The sum of the two errors is the (P + I) error.

The cycle rate used to reach and maintain the set point temperature is computed using the P + I control algorithm. The addition of the integral error is what differentiates the thermostat from many other mechanical and electronic thermostats.

For stage 2 of conventional systems or 2 stage heat pump without Aux Heat

The thermostat will use the stage of heating as needed to keep the indoor temperature within 1 °F (0.5 °C) degree of the set point. The thermostat turns on stage 2 when the capacity on stage 1 reaches 90%.

Heat pumps with electric Aux Heat when Differential is set to “Comfort”

The thermostat will use the stage of heating as needed to keep the indoor temperature within 1 °F (0.5 °C) degree of the set point. The thermostat turns on Aux Heat when the capacity on highest compressor stage has reaches 90%.

Heat pumps with electric Aux Heat when Differential is set to 2°F or higher (2 °F to 15 °F adjustable)

If the indoor temperature drops to the Differential amount while the highest compressor stage is running the thermostat will continue to run the heat pump stages and also energize the Aux Heat.

For example, if the Backup Heat Differential is set to 2 °F (1.0 °C), the indoor temperature must be 2 °F (1.0 °C) below the set point before the backup heat turns on. When a manual temperature change is made, there will typically be a delay before the thermostat brings on the backup heat, regardless of the upstage timer settings. When Differential is set to other than Comfort, the upstage timer and Holdoff timer settings are also available.

Dual Fuel heat pumps with gas or oil Backup Heat

If the thermostat is configured to control dual fuel, the Differential cannot be set to Comfort. It will default to 2 °F and can be adjusted from 2 °F to 15 °F.

If the indoor temperature drops to the Differential amount while the highest compressor stage is running the thermostat will end the call for the heat pump stages and run the fossil fuel heat stage.

For example, if the Backup Heat Differential is set to 2 °F (1.0 °C), the indoor temperature must be 2 °F (1.0 °C) below the set point before the thermostat will shut down the heat pump and run the fossil fuel heat.

When a manual temperature change is made, there will typically be a delay before the thermostat brings on the Backup Heat, regardless of the upstage timer settings.

The Upstage timer setting is only available when:

• The thermostat is configured for a heat pump with an aux heat stage (electric of fossil fuel)..

Backup Heat Upstage Timer options are Off, 30 minutes to 16 hours. Default is Off. If the differential is set to "COMFORT" then the upstage timer is limited to 30-60 minutes.

The upstage timer allows* the Aux Heat to run when the highest heat pump stage has run for longer than the timer setting during a steady state condition. Steady state means the thermostat is cycling to maintain set point.

Manually raising the set point or a scheduled set point change will not trigger the upstage timer. In those conditions the thermostat will not use Backup Heat unless a different condition triggers the thermostat to run the Backup Heat (Differential, balance point, or manually switching the thermostat to Em Heat mode).

*Differential and upstage timer are designed to restrict the auxiliary heat for customers who are energy conscious. The aux heat does not necessarily run after the timer has expired even in a steady state condition. Once the timer expires in steady state the thermostat calculates whether or not to run the aux heat based on the load capacity of the highest heat pump stage.

If the heat pump struggles to maintain set point, we would suggest one of the following steps:

1. Verify the heat pump is operating as expected.

2. Set a balance point. If a balance point is already used but the heat pump cannot handle the load even when operating correctly, the installer may need to raise this setting.

3. For heat pump with electric backup heat, set the Differential to “Comfort”, this uses the backup heat more aggressively.

The Backup Heat Holdoff Timer is available for any system with 2 heating types, the Backup Heat Differential is set to 2 °F (1.0 °C) or higher, and backup heat upstage timer is set to 30 minutes or more. Unlike the upstage timer, the holdoff timer can be activated by a temperature set point change (not limited to steady state). The holdoff timer starts when the highest stage of the previous equipment type turns on. The out-of-box setting is “Auto” and the thermostat will hold off the use of backup heat as long as possible when the set point is changed. If this is changed to a setting other than Auto, then the auxiliary heat will be FORCED to turn on after this time is met.

If the primary heat is making progress as expected, backup heat will not be used to reach the set point of the next program period. Backup heat is always restricted during a programmed recovery when the Adaptive Intelligent Recovery feature is used. See note below.

These settings allow the installer to keep the high stage of the equipment running until the desired set point is reached. This setting is recommended for Geothermal Heat Pumps to allow the loop to rest.

When set to no (default), the thermostat cycles the stages based on load conditions and the cycle rate setting for these stages.

• “Finish with High Cool Stage” is ISU 3020.

• “Finish with High Heat Stage” is ISU 3021.

• Set to Yes to turn on these features. The default is No.

ElitePRO™ Series Thermostats can be configured to control a 2-pipe fan coil or a 4-pipe fan coil.

Hot water fan coil - A hot water fan coil requires that the thermostat energize W to move hot water through a coil that is inside the HVAC supply ducting and then turn on the blower fan to blow air over the hot coil and deliver it to the space. The ElitePRO™ Series Thermostat energizes a single blower speed, wired to G for these systems.

4-pipe fan coil - A 4-pipe fan coil requires that the thermostat energize W to move hot water through a hot water coil or energize Y to move cold water through a cold water coil. Then the thermostat turns on the blower fan to blow air over the hot coil and deliver it to the space. Most 4-pipe fan coil units have multiple fan speeds. The low speed fan is wired to G. The medium speed fan is wired to Y. The high speed fan (if used) is wired to U. There are other special fan coil unit settings which can vary for different systems. These settings are covered in the Fan Coil Unit section.

2-pipe fan coil - A 2-pipe fan coil energizes the same terminal (Y) to move hot water through a coil as it does to move cold water through a coil. Therefore, a thermostat that controls a 2-pipe fan coil needs to know whether the pipe is hot or cold. When it senses that the pipe is hot, the thermostat automatically switches to heat mode. When it senses that the pipe is cold, the thermostat automatically switches to cool mode. If there is an emergency heat stage, the user can manually switch the thermostat to emergency heat mode when the pipe temperature is below the heat threshold setting. In that case, the thermostat energizes the Aux to run the backup heat.

The ElitePRO™ Series Thermostat has different options for how to perform the changeover from heat to cool based on pipe temperature.

• The ElitePRO™ Series Thermostat can be used with a 10K or 20K sensor

• The ElitePRO™ Series Thermostat can be used with a dry contact switch (such as an aquastat) to switch from heat mode to cool mode based on pipe temperature. The wiring diagrams for the fan coil unit section show how to wire the dry contact switch or wired sensor for this purpose. The ISU section shows the configuration settings.

When running heat or cooling, the ElitePRO™ Series Thermostat turns on the blower fan to blow air over the coil and deliver the conditioned air to the space. Most PTAC units have multiple fan speeds. The low speed fan is wired to G. The second speed fan is wired to Y2. On a system with 2 fan speeds Y2 is the high speed. On a system with 3 fan speeds Y2 is the medium speed. The third speed fan (if used) is wired to U.If U is used for a third fan speed, that will be the high speed. There are other special fan coil unit settings which can vary for different systems covered in this section.

PTAC - A PTAC operates the same as a heat pump except that it has multiple fan speed settings. If there is an emergency heat stage, the user can manually switch the thermostat to emergency heat mode. When in heat mode the thermostat can also energizes the Aux to run the backup heat

When running heat or cooling, the ElitePRO™ Series Thermostat turns on the blower fan to blow air over the coil and deliver the conditioned air to the space. Most PTAC units have multiple fan speeds. The low speed fan is wired to G. The second speed fan is wired to Y2. On a system with 2 fan speeds Y2 is the high speed. On a system with 3 fan speeds Y2 is the medium speed. The third speed fan (if used) is wired to U.If U is used for a third fan speed, that will be the high speed.

Fan Sequence Operations

(ISU 2105, 2106, 2107)

ISUs 2105 – 2107 are used to select the number of fan speeds controlled on a fan coil unit or PTAC system and assign (or be instructed) where these speeds are wired to.

(ISU 3320)

ISU 3320 allows the installer to select how the fan speed is controlled when the thermostat is controlling a fan coil unit or PTAC with multiple fan speeds. The options are Auto, Multiple Speeds, or All Allowed. When ISU 3320 is set for Auto, the thermostat uses the fan ramping algorithm to control the fan speed with a call for heat or cooling. The fan will be off with no call for heat or cooling. If ISU 3320 is set to Multiple Speeds, the user may select Lo, Med, or Hi from the fan menu. The thermostat will continuously run at the speed selected. If ISU 3320 is set to All Allowed, the user may select Auto, Lo, Med, or Hi from the fan menu. When Auto is selected, the fan runs only during heat or cool calls and the fan speed at which it runs is based on the control algorithm. If set to Lo, Med, or Hi, it will continuously run at the speed selected both in Idle and with a call for Heat or Cool.

(ISU 3325)

ISU 3325 allows the installer to select whether the fan always starts at the highest speed when there is a call for Heat or Cool. Some systems require this to ensure that the fan starts correctly. If enabled, the fan will start at the highest speed. If set to a speed other than High, the thermostat will then reduce the fan speed to the one selected in the fan settings or control to the correct speed based on the control algorithm if it is set to AUTO.

(ISU 3340)

ISU 3340 allows the installer to select whether the fan will reset to the Auto mode after a time delay when the user makes the setting Lo, Med, or Hi. The options are Off, 2 hours or 4 hours. If set to Off, the thermostat will run at the fan speed selected by the user indefinitely until the fan speed is changed manually.

(ISU 4010)

ISU 4010 allows the installer to determine if a pre-occupancy purge is used. This option applies to any light commercial application that has a fan and is using a schedule. This setting determines if the fan should run prior to the Occupied schedule, and if so how far in advance. If a system with multiple fan speeds is used, this option will run the fan at the highest speed during this time.

The ElitePRO™ Series Thermostat allows you to use Remote Setback (sometimes referred to as Occupancy sensing or Occupancy setback). This energy-saving feature can be enabled using the internal motion sensor on select ElitePRO™ Series Thermostats, one or more wireless indoor sensors, or with an occupancy sensor that opens or closes a dry-contact switch.

During occupied periods, the occupancy sensor tells the thermostat to switch to STANDBY (Setback settings) when no one is in the room. If someone is in the room, the sensor follows the settings of the Occupied period. The occupancy sensor is ignored during unoccupied periods. If someone is in the room, the sensor follows the schedule settings set by the installer or a manual override setting (if not locked out by installer/property manager).

To use the feature for energy savings when a room is unoccupied, but no regular Occupied schedule has been set:

The installer can access the Schedule menu and disable any scheduled period except Occupied 1 (Commercial) or Wake (Residential). In this way, the thermostat will have an Occupied schedule setting to which it can default when occupancy is detected.

ISU settings 2240, 6020, 6030 & 6040 are related to occupancy sensing. If an occupancy sensor opens or closes a switch when occupancy is detected, that switch is wired to R at HVAC and L at the thermostat when an EIM is not used. If an EIM is used, the switch is wired to S1, S2, S3, or S4 terminals.

A Remote Setback Time Delay (ISU 6030) can be set to force the thermostat to wait before it switches from occupied settings to the standby settings. This allows the room to stay comfortable if the room is unoccupied for a short period of time. When set to 0 minutes, the thermostat will switch from occupied settings to the standby settings immediately when the room is unoccupied.

Hotel Card Reader:

Some Fan Coil Unit thermostats used in hotels use a remote setback triggered by a room key card holder. If the guest inserts the key card into the holder while in the room, the thermostat will switch to Occupied temperature settings. When using an EIM, the wires from the card reader go to the S contacts on the EIM. If the EIM is not used, one of these wires goes to R at HVAC and the other wire goes to L at thermostat/UWP. See the wiring diagrams.

Set Up Remote Setback

1. Select a remote setback option in ISU 2240 (see Figure below). Select ElitePRO thermostats and wireless indoor sensors have a built-in motion sensor. The “Dry Contact” or “L Terminal” settings require an external occupancy sensor which opens or closes a switch when occupancy is detected.

   

   Left image shows options when EIM is used, Right image shows options when EIM is not used. For Either option, you can scroll down to select “Wireless and Internal Sensor” not shown in images.

   Do not set the ElitePRO for Remote Setback using the Internal sensor when it is used with an EIM. The follow up timer and standby settings are not displayed, and the feature will not go into setback. The EIM4010 firmware will be updated in the future to support the internal sensor. Currently, you can use Remote Setback with wireless sensors or a dry contact sensor when an EIM is used. The internal sensor options are operational when an EIM is not used.

2. If a dry contact is used to initiate Remote Setback and an EIM is used, 6010 is used to assign the Occupancy Sensor to a set of S contacts on the EIM.

   

3. The setting below is shown if either Dry Contacts or L Terminal is selected for 2240. Select Normally Open when Occupied or Normally Closed when Occupied, based on the type of dry contact device installed.

• Normally Open when Occupied: The Dry Contact device is open when the room is occupied and will close when the room is unoccupied.

• Normally Closed when Occupied: The Dry Contact device is closed when the room is occupied and will open when the room is unoccupied.



4. ISU 6030 is shown unless No Remote Setback is selected for ISU 2240. Select a Remote SetbackTime Delay . The Remote Setback Time Delay forces the thermostat to wait before switching from Occupied settings to the Standby settings.

   When using wireless sensors and/or the internal radar sensor, the time delay set for ISU 6030 does not start countdown immediately after the room becomes vacant. The thermostat uses an occupancy algorithm based of motion events detected within a specific timeframe. Typically, the delay will be at least 10 minutes after the last detected occupancy event, plus the time configured in ISU 6030. After the timeout, the thermostat will switch from using the occupied heat/cool settings to the standby settings in ISU 6040.

   

5. Select the Standby settings that you wish to maintain when the occupancy sensor detects that the room is unoccupied.

   EIM S Terminal wiring for Occupancy Sensor

   Occupancy sensor/switch can be wire to any of the 4 sets of S terminals on the EIM (S1, S2, S3 or S4). Configure ISU Settings 2240, 6010, 6020, 6030, and 6040 on the ElitePRO™ Series Thermostat for Remote Setback.

   Remote Setback using a Dry contact switch on a ElitePRO™ Series Thermostat Without EIM

   

Hotel Card Reader retrofit

If wires going to S and S on a previous thermostat went to a card reader or other dry-contact occupancy sensor, they can be wired to the ElitePRO™ Series Thermostat or EIM as shown in the diagrams below.

A 10K/20K cannot be wired to L or R as shown below. A 10K/20K sensor wires to a set of S terminals at either EIM or ElitePRO™ Series Thermostat/UWP.

In retrofit installations: If the ElitePRO™ Series Thermostat is used without EIM, you can pig-tail one of the existing wires to R at the thermostat. Polarity does not matter when re-wiring to R and L at UWP. Then follow the following ISU settings.

A Dry Contact device such as a wet switch can be connected to the S terminals at the UWP or S1, S2, S3, or S4 terminals at the Equipment Interface Module. When the dry contact device detects a problem, the thermostat displays an alert on the home screen along with the dealer information.

If the thermostat is part of Pro IQ services, the message will also be shown in the pro software and the homeowner’s app.

When the user touches the alert for more info, the Notification screen is displayed, prompting them to contact their dealer.

The following Dry Contact Alerts are available for the ElitePRO™ Series Thermostat:

Full Drain Pan Alert

When the dry contact device detects that the condensate drain pan is full, the thermostat provides an alert to the user.

Dirty Filter Alert

When the dry contact device detects a dirty air filter (pressure drop across the filter), the thermostat provides an alert to the user to replace the filter.

Water Leak Alert

When the dry contact device detects a water leak, the thermostat provides an alert to the user.

System Shutdown Alert

When the dry contact device detects a critical problem with the system, the thermostat alerts the user that the system was shut down. When the dry contact device detects a problem with the system (for example, smoke detection), the thermostat will not call for heating, cooling, fan or IAQ equipment until the dry contact is deactivated or the feature is no longer configured at the thermostat.

Service Needed Alert

When the dry contact device detects an issue that requires service, the thermostat provides an alert to the user.

Fan Failure Alert

The Fan Failure Alert protects the equipment when there is no airflow. When the dry contact device (for example, sail switch) detects no airflow for 5 minutes after a call for forced air heat, cool or fan, the thermostat alerts the user that the system was shut down due to a lack of airflow. The thermostat will call for the fan and lock out all other equipment until the dry contact device senses air flow again or the feature is no longer configured at the thermostat.

Custom Alert

Allows the dealer to enter a custom alert to be displayed when a dry contact device is activated. For example, a float switch can detect when your sump pump is not working.

Dry Contact Setup Example

Custom Alerts 1 through 4

Allows the dealer to enter a custom alert to be displayed when a dry contact device is activated. For example, a float switch can detect when your sump pump is not working.

When Custom Alert 1 through Custom Alert 4 is selected in ISU 6005, the ElitePRO™ Series Thermostat asks you to name the alert and then gives options for additional settings related to the alert. These settings are:

• Which set of S terminals on the UWP or EIM the Dry Contact Alert is wired to (ISU 6190).

  • There are S terminals on the UWP and four (4) sets of S terminals on the EIM. If a set of S terminals is already configured for use by a different Dry Contact Alert (or sensor), it will not be configurable.

• Whether the switch wired to these terminals is normally open or closed (ISU 6200).

  • The switch wired to the S terminals could either be open in normal (not alert) conditions or closed.

• Enter the Dry Contact Alert name (ISU 6210).

• Whether there is an alert message displayed when the alert is active (ISU 6215).

  • In most cases, the installer would want an alert message to appear on the ElitePRO™ Series Thermostat if there was a Dry Contact Alert active. However, the installer may be using the “alert” to do some other action (like running a ventilator when a sensor is reading high CO2). This may be normal operation and they may not wish to show an alert.

• Lock Out Heat or Lock Out Cool (ISU 6230)

  • If the installer chose to lock out heat or cool on a custom Dry Contact Alert condition, the thermostat will then ask if: "You want a delay before the lockout (ISU 6600 or 6620). For example, if someone was using a door sensor to lock out cooling, you wouldn’t want to short cycle the cooling every time someone enters or exits. But if the door is left open for a certain length of time, you may wish to shut down the heat or cooling." Or, "If you still want a maximum temperature for cool (ISU 6610) or minimum indoor temperature for heat (ISU 6630). Example: If someone had a heat lockout configured when the window was open, they left the window open, and the indoor temperature dropped to 40°F, you probably still want the heat to run because the danger of pipes freezing overrides the inefficient use of heating with a window open"

• Activate Fan (ISU 6230)

  • If selected, this setting turns on the fan when the selected custom Dry Contact Alert (custom dry contact 1 through 4) is active.

• Activate Custom U terminal (ISUs 6230, 6240, 6250, 6260)

  • If you choose to activate a custom U terminal during a custom alert, the ElitePRO™ Series Thermostat will ask you to name the U terminals used. That way the ElitePRO™ Series Thermostat equipment status menu can show what is being turned on or locked out. For example, you could wire a shut off valve to the U contacts and the status would then show “Shut off valve energized” under equipment status.

• Humidifier Lockout (ISU 8095)

  • If the ElitePRO™ Series Thermostat is set for a custom Dry Contact Alert and to control a humidifier, you can choose to lock out the humidifier during a custom Dry Contact Alert (the Water Leak Alert option also offers this setting).

• Dehumidifier Lockout (ISU 9145)

  • If the ElitePRO™ Series Thermostat is set for a custom Dry Contact Alert and to control a dehumidifier, you can choose to lock out the dehumidifier during a custom Dry Contact Alert.

• Turn On Ventilator (ISU 10065)

  • If the ElitePRO™ Series Thermostat is set for a custom Dry Contact Alert and to control a ventilator, you can choose to turn on the ventilator during a custom Dry Contact Alert.

• Lockout Ventilator (ISU 10140)

  • If the ElitePRO™ Series Thermostat is set for a custom Dry Contact Alert and to control a ventilator, you can choose to lock out the ventilator during a custom Dry Contact Alert.

The ElitePRO™ Series Thermostat can be set up for residential or light commercial applications (ISU 1010). When the thermostat is set up for Commercial, the thermostat meets Commercial Code, Title 24 and provides the following features:

• Commercial language (Occupied and Unoccupied)

• Temporary override (permanent hold is not allowed)

• Temporary override duration is limited to the amount set by the installer

• Adjustable ramp rates

• Initiate occupancy

• Displays name on home screen

• Remote setback using an occupancy sensor

• Economizer or Time of Day output

• Pre-occupancy purge

• Additional dehumidification control options

Commercial Use

Touch 5or 6 to adjust the temperature. It will be maintained until the hold time you set.

• To change the hold time, touch Hold Until. Then use the arrow buttons to change hold time. This time can be adjusted up to the maximum time set by the installer.

• Touch Override to use a pre-set occupied temperature if a person uses the room during an unoccupied period. The new temperature will be maintained for 1 hour and can be adjusted up to the maximum time set by the installer.

The programmed schedule will resume when the override timer expires. Touch Cancel Hold at any time to resume the program schedule.

This feature keeps temperature at an energy-saving level after the thermostat transitions from an Unoccupied schedule period to an Occupied schedule period until someone touches Start occupancy. When you arrive, touch the button to maintain a comfortable temperature while the room is occupied. This feature might be used in a school room that isn’t occupied every day.

Touch the 5or 6buttons to set the temperature or the Hold Until time. The temperature is maintained until the time you set. Temperature returns to an energy saving level after the timer expires, or the Occupied period ends.

This feature is available only when programmed by the installer in ISU 4020 & 4030.

When the ramp rate is set to Off, the thermostat begins recovery at the scheduled time.

When a ramp rate is set, recovery begins early to reach the setpoint by the program time. Based on your recovery ramp setting and how far the thermostat is set back, the thermostat determines how early to turn on the system.

If the ElitePRO™ Series Thermostat is set to use a wired sensor, wireless sensor, or Internet for outdoor temperature (ISU 1060), you can set outdoor temperatures for mild, cold and hot days in your region. By setting these outdoor temperatures, the thermostat will automatically adjust the ramp rate based on outdoor conditions. This allows the thermostat to save energy by starting recovery at the optimum time as outdoor conditions change.

The thermostat location (name) can be displayed on the home screen. See the name “OFFICE”. This is useful when multiple thermostats are mounted in a manager’s office or equipment room, to quickly identify which thermostat controls a specific zone or area.

When configured for Commercial application, the ElitePRO™ Series Thermostat will ask you to select the room where it is installed during initial setup. If you select Yes for ISU 1030, this is the name that will be displayed on the home screen. To change the name after setup is complete, go to Installer Options > Devices and Sensors-Thermostat. Then select Change Room. You may choose a pre-selected room name or choose Other-Add-Room to enter a custom name.

Economizer

The thermostat can control an Economizer module to provide ventilation during occupied periods and free cooling when outdoor conditions are favorable. In some climates the cooling system may run several hours when it may not be required to maintain indoor comfort. When outdoor conditions are favorable, ventilation with outdoor air can achieve the same level of comfort at lower cost.

The thermostat works with the Jade W7212 Economizer Module for conventional systems and the Jade W7213 and W7214 Economizer Modules for heat pump systems.

* Fan (G) always energized during Occupied & Occupied Temporary modes.

Time of Day (TOD)

The ElitePRO™ Series Thermostat can be set up for a Time of Day output in the installer setup. This output is commonly used to control lighting panels, turning them on for occupied periods and off for unoccupied periods.

The Economizer Module and Time of Day output connect to the U terminal at the thermostat or EIM and are set up at ISU 6050 and 2217, 2220.
