be operated.
2) The setup temperature is shifted (corrected) in the
range not to lose the comfort ability according to input
values of various sensors.
3) Data (Input value room temp. Ta, Outside temp. To, Air
volume, Indoor heat exchanger sensor temp. Tc) for
20 minutes are taken the average to calculate correc-
tion value of the setup temperature.
4) The setup temperature is shifted every 20 minutes,
and the shifted range is as follows.
In cooling time: +1.5 to – 1.0K
In heating time: –1.5 to +1.0K.
1) This control is operated by selecting [AUTO] operation mode.
2) COOL operation mode:
