line downward. If the room temperature falls to a temperature that is 2°F below

the heating setpoint, the heating will be enabled, and the unit will be in the

heating mode. Continue following the solid line in a clockwise direction to the

heating setpoint. Once the room temperature rises to the heating setpoint, the

heating mode will be disabled, and the room will be in the ventilation mode.

Cooling Mode

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.
