Thermostat - Rt6
Mode of Operation
The RT6 is a 1-stage or 2-stage heat thermostat. It functions with air conditioning, heat pumps, or
electric heat systems.
The thermostat activates the heating appliance when the room temperature is below the set heat
temperature (by the dierential temperature). The RT6 will stop outputting when the call for heat has
been satisfied. With heat pumps, the thermostat will not let the compressor come on for 4 minutes
after it turns o. This protects your compressor.
When the room temperature is greater than the set cool temperature (by the dierential temperature),
the cooling device is activated. The RT6 will stop outputting when the call for cooling is satisfied.
The thermostat will not let the compressor come on for 4 minutes after it turns o. This protects your
compressor.
The RT6 has three possible operating modes: OFF , Heat , and Cool mode. In o mode, the
thermostat will not turn on heating or cooling devices. The manual fan can be turned on in all
operating modes using the fan button. In heat mode, the thermostat controls the heating system. In
the cool mode, the thermostat controls the cooling system.
