Wireless remote
control
(RBC-AMS55E*)
is required.
When the "Energy saving operation" is selected during
AUTO mode, energy-saving operation will be carried out.
(In RBC-AMS55E*, COOL and HEAT mode can also be
selected.)
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 correction
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:
It is controlled according to the
following figure if To < 28˚C.
Remarks
3) HEAT operation mode:
It is controlled according to the
following figure if To > 15˚C.
