9. Room Temperature Control
The thermostat is switched on/off by ∆T as follows.
∆T = (Room temperature) – (Set temperature)
Remote control sensor Room temperature = remote control sensor detection temperature
Body sensor Room temperature = (Body sensor detection temperature) – (Air-intake shift temperature*)
* Shift temperature (valid only for heating)
In heating mode, a temperature difference occurs between the upper part and lower part of a room. The value is set
in consideration of the difference between the temperature detected by the body sensor located in the upper part of
the room and the temperature detected in the lower part of the room.
0 ˚C ~ 10 ˚C can be selected with the remote controller simple setting mode.
(Factory settings: floor standing type ----- 0 deg; wall-mounted type ----- 2 deg; other types ----- 4 deg)
Supplement:
(1) After thermo-on, it will not thermo-off for 3 minutes due to ∆T .
However, for heating, if the indoor coil E2 temperature ] 64 ˚C, it will thermo-off within 3 minutes (over load
protection).
(2) After thermo-off, it will not thermo-on for 1~3 minute.
For cooling or dehumidifying, it will not thermo-on if the indoor coil E1 or E2 temperature < 6 ˚C even after the
above-mentionned period of time has passed.
(3) When the system is set for test operation, it will not thermo-off for 60 minutes (forced thermo-on).
