Cooling Mode allows the cooling to operate as needed and is activated whenever
the room temperature is 2° above the cooling setpoint. In the Cooling Mode the
cooling output will cycle to maintain a constant room temperature. The cooling
output does not have an anti-cycle delay.
The MDT control system does not support the Cooling Mode.
To change the desired cooling room temperature of an MRT control system,
rotate the temperature setpoint knob on the remote panel clockwise to the
desired temperature. The allowable temperature range is 55°F - 90°F . The cooling
will be disabled when the room temperature drops to the Cooling Setpoint.
