Unit Operating Modes

UNIT MANUAL MODE

Manual Mode allows the unit to turn on regardless of the Time Clock or Night Setback functions. A BACview or PC is required to change to this mode. See the section related to the MRT Expert for instructions on how to use the BACview for programming.

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. A BACview or PC is required to change to this mode. See the section related to the MRT Expert for instructions on how to use the BACview for programming.

Unoccupied/Occupied Control. Once the unit is placed in the Auto Mode, the unit can be controlled from the keypad on the MRT-Pro room sensor. The MRT- Pro room sensor display will indicate the unit is in the un-occupied period. To turn the unit on and place it in the occupied period press the "Manual On" button on the face of the MRT-Pro room sensor. Pressing the "Warmer" button can increase the amount of "on" time. Pressing the "Cooler" button can decrease the amount of "on" time. Each press decreases the time in 30-minute increments. Each press increases the time in 30-minute increments to a maximum of 9 hours of "on" time.

To turn the unit off and place it in the un-occupied period press the "Manual On" button on the face of the MRT-Pro room sensor. The display will indicate the amount of "on" time remaining. Press the "Cooler" button repeatedly until the time reaches zero, and the unit shuts off. Each press decreases the time in 30- minute increments.

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.

Scheduling Time Clock. This function requires the purchase of a BACview or a direct PC interface to the unit controller. See the section related to the MRT Expert for instructions on how to use the BACview for programming.

Heating Night Setback. The Heating Night Setback function automatically cycles the unit "on" if the room temperature falls below the Heating Night Setback temperature setpoint, and the unit is scheduled to be "off". If the unit is scheduled to be "off" and the Heating Night Setback function turns the unit "on", the unit will be cycled "off" once the room air temperature has risen 2° above the Heating Night Setback setpoint. The default for this setpoint is 55°F and is fixed at 10° below the Heating setpoint. Changing the Heating setpoint changes the Heating Night Setback setpoint

Cooling Night Setback. The Cooling Night Setback function automatically cycles the unit "on" if the room temperature rises above the Cooling Night Setback temperature setpoint, and the unit is scheduled to be "off". If the unit is scheduled
