Mode of Operation
The thermostat is a programmable, manual or auto changeover, up to 2-stage heat (depending on your model) and up to
2-stage cool (depending on your model) thermostat. It functions with air conditioning, heat pumps, gas, oil, or electric heat
systems. An outdoor sensor can be used to monitor the ambient temperature. A second remote sensor may be used to monitor
the temperature in another area. The thermostat activates the heating appliance when the room temperature is below the set
heat temperature (by the differential temperature). When the call for heat has been satisfied, the outputs are turned off. With
heat pumps, the thermostat will not let the compressor come on for 4 minutes after it turns off to protect your compressor.
When the room temperature is greater than the set cool temperature (by the differential temperature), the cooling device is
activated. When the call for cooling has been satisfied, the outputs are turned off. The thermostat will not let the compressor
come on for 4 minutes after it turns off to protect your compressor.
The program schedule can be overridden by changing the set temperature (
or
). This puts the thermostat into a
temporary hold. It will automatically return to the program schedule at the next program schedule transition.
This thermostat is also capable of controling a humidifier or dehumidifier. When set to humidification, the thermostat will turn
on the humidification system when the relative humidity is lower than the set humidity, by the differential. When the relative
humidity reaches the differential humidity set, the thermostat will turn off the humidification system. If the thermostat is
controlling a dehumidifier (including an air conditioner), the thermostat will turn on the dehumidifier when the relative humidity
is above the setpoint humidity, by the differential. Depending on the settings, when the relative humidity reaches the differential
humidity set or the room temperature is 3°F below the set cooling temperature, the dehumidifier is turned off.
