3.3.1.4
All output (air refresh, AUH, air ventilate, etc.) is effective.
3.3.1.5
In cooling mode, the original set temperature is Ts=Tr-5
℃
and 22
℃
≤
Ts
≤
27
℃
, then the master unit
will not change operation mode when the unit enters cooling mode.
If users want to change working condition by remote controller, in case the condition will not conflict with the
master unit mode, ( such as cooling mode conflicts with AUH mode), the master unit will operate and
display in new condition set by remote controller.
3.3.1.6
In heating operation, when the temperature Ts=Tr+8
℃
and 16
℃
≤
Ts
≤
22
℃
, then the master unit will
not change operation mode when the unit enters heating mode.
If users want to change working condition by remote controller, in case the condition will not conflict with the
master unit mode, the master unit will operate and display in new condition set by remote controller.
3.3.2 Cooling:
Temperature control range: 16
℃
-32
℃
; Original value: 24
℃
;
Temperature control precision: ±1
℃
;
Characters on control:
4-way reversing valve closes:
When Tr
≥
Ts+1
℃
, compressor runs; When Tr
≤
Ts-1
℃
, compressor stops; The control circuit will stop
compressor only after it has run at least 5 minutes. The compressor can be restarted 3 minutes later the
turn-off.
Fan speed control:
Auto: When Tr>Ts+2
℃
, high speed;
When Ts< Tr
≤
Ts+2
℃
, medium speed;
When Tr
≤
T, low speed.
Manual: Users can select the fan speed of high, medium or low level as needed when the air
conditioner is in the turn-on status.
Louver adjustment:
Manual (vertical direction): Set the blades position as needed. (Position 1-5 in figure 1.)
Auto (vertical direction): The range of sweeping is in position 2-5, swinging speed is 5 degree/second.
3.3.3. Dehumidification:
Temperature control range: 16
℃
-32
℃
; Temperature control precision: ±1

;
Characters on control:
4-way reversing valve closes.
When Tr
≥
Ts+2
℃
,the running mode is the same to the cooling operation;
When Ts-1
℃
< Tr < Ts+2
℃
, compressor and outdoor fan motor run continuously. And indoor fan motor
runs at low fan speed
When 15
℃
< Tr < Ts-1
℃
, compressor and outdoor fan motor are working according to 3 minutes
working alternating with 9 minutes stopping. Indoor fan motor runs at low fan speed when compressor is
running, and it runs at breeze level for 30 seconds later the turn-off of compressor. 30 seconds later, fan
motor will turn off.
