• The fan motor works as set if the he heat exchange
temperature remains 35 ºC for more than 4 minutes
• The fan motor works as set if the he heat exchange
temperature remains above 38 ºC.
When the compressor stops and remains idle for 3
minutes
20 seconds after the compressor stops, the up wind
volume is weak (switching to SSLO in silent running
mode) and then slightly weak. While the down wind volume
is stoped. If the compressor stops when the heat running
starts, the wind volume is weak.
High Work-intense protection control
Under the heating mode, the high work-intense protection
will be carried out according to the heat-exchange tem-
peratures as shown in the table below.
High Work-intense protection control:
9 PCB Explanation
• High Work-intense protection alarm will start if
there are two times of high work-intense protection
within 30 minutes.
• If the heat-exchange temperature does not reach
THHEAT 2, it will resume to the normal temperature
level control
• The smaller one of the high work-intense frequency
and level frequency will be the operation data.
Low Work-intense protection control
Specification for heat-exchange temperature sensor
B fixed number=3700 R(25�)= 10K�
Under the cooling /moisture removing modes, the low
work-intense protection will be carried out according to
the heat-exchange temperatures as shown in the table
below.
Low Work-intense protection control will be neglected in
the trial running.
Low Work-intense protection control will be cancelled for
3 minutes temporarily after the powerful cooling starts
for 1 minute.
Dehumidification running
Under the dehumidification mode the fan motor stops as
the compressor stops.
The operation is weak after 3 minutes’ idle mode.
After stand by for 3 minutes, the compressor is on.
The compressor operates as the set wind volume when
the wind volume is set to be strong, medium or weak.
The wind volume is decided according to the temperature
adjusting when the wind volume is set to be automatic.
Automatic running
When the operation mode switches to automatic after
the unit is powered on, the system will choose the ope-
ration mode according to the difference between the
current set temperature and the room temperature. And
then it will follow the selected mode to operate. The Tr
represents room temperature and Ts represents the set
temperature.
When entering into the automatic mode for the first time,
please select the operation mode with the conditions below.
