Mode Code
H04=0
Function
Dehumidification
Relay 1
High fan speed
Relay 2
Medium fan speed
Relay 3
Low fan speed
Relay 4
Compressor
Relay 5
Air damper open
Description
If the humidity of the air is higher than the setting, the fan turns on; 5 seconds later,the
compressor turns on;.
If the humidity of the air is lower than the setting, the compressor turns off; 3 minutes later,the
fan turns off.
Initial Value
The controller has data memory function when there is power failure.
The initial value as below:
• Fan speed - high;
• Air damper - close;
• Mode - the same before the power failure.
Fan Control
The initial value is high speed, can be adjusted manually.
EC motor (0~10V) fan has 5 fan speeds, which can be set separately.
AC motor fan speed can be adjusted manually when H04=0:
• F01=1, high fan speed available;
• F01=2, high fan speed & low fan speed available;
• F01=3, high fan speed & medium fan speed & low fan speed available.
High fan speed & low fan speed available when H04=1.
High fan speed available when H04=2.
Fan works according to F02 when achieve the set humidity and temperature (only for the
available system working mode):
• F02=1, the fan turns off 3 minutes later after achieved the set humidity and temperature
(only for the available system working mode);
• F02=2, the fan keeps working after achieved the set humidity and temperature (only for
the available system working mode).
