Unit Operating Modes
MRT Controls:
MRT, modulating room temperature, is the most basic AdaptAire control for room temperature. The MRT control system includes a remote control panel equipped with 1 or 2 potentiometers, 3 or more pilot lights, and up to 2 switches.
UNIT OFF MODE
Off Mode is the default unit operational mode. To place the unit in Off Mode rotate the "temperature setpoint" knob on the remote control panel counterclockwise to the stop. This will place the unit in the OFF mode and extinguish the "unit enable" light. The OFF mode prevents the unit from starting.
UNIT MANUAL MODE
Manual Mode allows the unit to turn on To place the unit in Manual Mode rotate the "temperature setpoint" knob on the remote control panel clockwise to the desired room temperature setpoint. This will place the unit in the MANUAL mode. The burner will be enabled if the room air temperature is 2° below the room temperature setpoint and will be deactivated when the room air temperature is above the room temperature setpoint. The cooling output will be enabled if the room air temperature is 2° above the room temperature setpoint and will be deactivated when the room air temperature is below the room temperature setpoint.
UNIT AUTO MODE
Auto Mode has four different functions that control the unit operation. They are a time clock, heating and cooling night setbacks, and a signal from an external source.
The MRT control does not support the time clock, night setback, or auxiliary unit enable functions.

UNIT OFF MODE
Off Mode is the default unit operational mode. The OFF mode prevents the unit from starting and overrides the Time Clock and Night Setback functions. A BACview or PC is required to change from this mode. See the section related to the MRT Expert for instructions on how to use the BACview for programming.
