In case of wall mounted type, only LL airflow blows
when thermo. OFF.
(5) When thermo. ON
Cooling operation • Auto setting : Conforms to the
procedure of “Fan speed auto
control”
• Regular fan speed setting :
Conforms to the set fan speed
Heating operation • At start of operation : Con-
forms to the procedure of
“Cold draft prevention”
• Later
- Fan speed auto setting :
Conforms to the procedure
of “Fan speed auto control”
- Regular fan speed setting :
Conforms to the set fan
speed
¶ Fan speed auto control : Controlled by ∆T (Room
temp - Set temp)
Supplement
The following heating controls receive priority, while
heating.
(2) Fan operation : Set fan speed
(3) Dry operation : L
(4) When thermo. OFF
Cooling Set fan speed
Heating
* Shift temp (valid while heating, only) is set when
shipped from factory as follows:
+4 deg: all type except wall mounted and floor
standing type
+2 deg: wall mounted type
0 deg: floor standing type
Shift temp can be set with Remote controller from +1
to +10 deg.
The thermostat turns ON / OFF with the following ∆T.
∆T = Room temp - Set temp
With body thermostat Room temp = (Body sensor) - (Shift temp*)

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 5
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 < 2 ˚C.
(3) When the system is set for test operation, it will
not thermo.-off for 60 minutes (forced thermo.-
on).
