RedLINK Communication:

Frequency: 900 MHz frequency range

Re-Sync Time: RedLINK devices re-establish communication within 6 minutes after AC power resumes.

Temperature Setting Range:

Heating: 40 to 90 °F (4.5 to 32 °C).

Cooling: 50 to 99 °F (10 to 37 °C).

NOTE: Adjustable high and low range-stop settings.

Humidification Setting Range:

0% to 90% RH.

Dehumidification Setting Range:

10% to 100% RH.

Humidity Display Range:

0% to 99%.

Humidity Sensor Accuracy:

± 5% RH from 30% to 50% RH at 75 F.

Cool Indication:

Display floods blue and says "Cooling to" when Cool is on.

Heat or Em Heat Indication:

Display floods orange and says "Heating to" when Heat is on.

AUX Heat Indication:

Display shows “Aux Heat On” above the room temperature.

Interstage Differential:

Comfort (default setting):

The thermostat keeps the indoor temperature within 1 degree of the setpoint (Differential less control). Unless the system is dual fuel, or a Differential setting is used, the thermostat turns on stage 2 when the capacity on stage 1 reaches 90%.

• See ISU 3030 for cool differential options.

• See ISU 3050 and ISU 3090 for Backup Heat Differential options.

Clock Accuracy:

1 minute per month at 77 °F (25 °C). ± 2 minutes per month over the operating ambient temperature range. Automatically updates when connected to WiFi router and registered to account.

Mounting Means:

Thermostat mounts directly on the wall in the living space using mounting screws and anchors provided. Can mount to a horizontal 2 x 4 in. junction box using J-Box adapter (included).
