Night Setback - Mitsubishi Electric PAC-ZC40L Instruction Book

Function settings

Night setback

The Night setback function starts heating operation when a given group is stopped and
the room temperature drops below the specified lower limit temperature. Also, this function
starts cooling operation when a given group is stopped and the room temperature rises
above the specified upper limit temperature.
* If the room temperature is measured by the return air temperature sensor on the air conditioning unit,
the measured value may not be an accurate representation of the temperature in the room, especially
when the air conditioning unit is stopped and the room air is stagnant. When this is the case, use
optional sensor or remote controller sensor to measure the room temperature.
