(1) Auto operation
(a)
If “Auto” mode is selected by the remote control, the heating and the cooling are automatically switched according to the
difference between outdoor air temperature and setting temperature and the difference between setting temperature and return
air temperature. (When the switching of cooling mode
↔
heating mode takes place within 3 minutes, the compressor does
not operate for 3 minutes by the control of 3-minute timer.) This will facilitate the cooling/heating switching operation in
intermediate seasons and the adaptation to unmanned operation at stores, etc (ATM corner of bank).
Notes (1) Temperature range of switching cooling/heating mode can be changed by RC-EX1A from ±1.0
～
±4.0.
(2) Room temperature control during auto cooling/auto heating is performed
according to the room temperature setting temperature. (DIFF: ±1 deg)
(3) If the indoor heat exchanger temperature rises to 59°C or higher during
heating operation, it is switched automatically to cooling operation. In
addition, for 1 hour after this switching, the heating operation is not
performed, regardless of the temperature shown at right.

(b) The following automatic controls are performed other than (a) above.
(i) Cooling or heating operation mode is judged according to the conditions of the "Judgment based on Setting tempe
Cooling select temperature and Indoor return air temperature" and the "Judgment based on Outdoor temperature".
1)
In "Setting temperature - Cooling select temperature < Indoor return air temperature" and "Outdoor temperature/Cooling < Outdoor
return air temperature"
⇒
Operation mode: Cooling
2)
"Setting tempe Heating select temperature > Indoor return air temperature" and "Outdoor temperature/Heating >
Outdoor air temperature"
⇒
Operation mode: Heating
3) The outdoor air temperature of the above judgment conditions is sampled at every 10 minutes.
4) In the range where the above cooling and heating zones are overlapped
