Program Schedule

You can program four time periods each day, with different settings for weekdays and weekends. We recommend using the presets shown in the table at right; these presets are designed to reduce your heating/cooling expenses.

WAKE: Set to the time you wake up and your desired temperature during the morning until you leave for the day.

AWAY: Set to the time you leave home and your desired temperature while you are away (usually an energy-saving temperature).

HOME: Set to the time you return home and your desired evening temperature until bedtime.

SLEEP: Set to your bedtime and your desired overnight temperature (usually an energy-saving temperature).

Depending on what type of schedule the thermostat was set up for, days may be grouped or set individually.

Smart Response Feature

This feature allows the thermostat to “learn” how long the furnace and air conditioner take to reach programmed temperature settings, so the temperature is reached at the time you set. For example:

Set the Wake time to 6 am and the temperature to 70°. The heat will come on before 6 am, so the temperature is 70° by the time you wake at 6. The message “Active Recovery” is displayed when the system is activated before a scheduled time period.

Program schedule override (Temporary)

  1. Press or to adjust the temperature.

  2. Once at the desired setpoint temperature, no further action is needed. The new setpoint temperature will be held until the next scheduled time period begins.

  3. Press the SAVE button or wait for the display to time out and return to the Home screen.

To cancel the Temporary Hold, press and release the HOLD button to cycle through the settings until CANCEL HOLD is selected.

Built-In Compressor Protection

Damage can occur if your system’s compressor is restarted too soon after shutdown. This feature forces the compressor to wait for a few minutes before restarting. During the wait time, the display will show the message Waiting For Equipment under the room temperature reading.

When the safe wait time has elapsed, the message disappears, and the thermostat will show “Heat on” or “Cool on”.
