Temperature Setting Range:
Heating: 40 to 90 °F (4.5 to 32 °C).
Cooling: 50 to 99 °F (10 to 37 °C).
Humidification Setting Range:
10% to 60% RH.
Dehumidification Setting Range:
40% to 80% RH.
Humidity Display Range:
0% to 99%.
Cool Indication:
Prestige 2.0 and Prestige IAQ 2.0 displays “Cool On” when the
thermostat turns the cooling on.
Heat Indication:
Prestige 2.0 and Prestige IAQ 2.0 displays “Heat On” when the
thermostat turns the heating on.
Auxiliary Heat Indication:
Prestige 2.0 and Prestige IAQ 2.0 displays “Auxiliary Heat On”
when the thermostat turns the auxiliary heat on.
Interstage Differential:
Comfort: The thermostat keeps the indoor temperature within 1
degree of the setpoint (droop less control). The thermostat
turns on stage 2 when the capacity on stage 1 reaches
90%.
When the interstage differential is set to 1.0 or higher, the ther-
mostat stages the equipment based on how far the indoor
temperature is from the setpoint (ISU 3030 to 3090). See
page 21 for more information.
