* Set Back Operation
In this operation, a time interval when the air conditioning load becomes lower is designated, and during this
time interval, the temperature during air conditioning is set so that it is several degrees higher than the
normally set temperature, and during heating, the temperature is set so that it is several degrees lower than
the normally set temperature. Through this kind of operation control, running costs can be reduced. The
amount of set back can be set at 1, 2, 4, 6 and 8
°
C (2, 4, 8, 12 and 16
°
F).

specified for set back, the thermostat setting rises
automatically by 2
°

turns to the normal setting after the set back time
is ended.
