1.Through the hysteresis setting, the system can adjust the load effectively.
2.The adjusting logic of cooling mode :
(The parameter of δ1,δ2,Tj1 and Tj2 are decided by the outdoor unit)
(the parameter of δ1,δ2,Tj1 and Tj2 are
decided by the outdoor unit)
3: The adjusting logic of heating mode:
(the parameter of δ1,δ2,Tj1 and Tj2
are decided by the outdoor unit)
(TAL: total outlet water temperature)
● Fault alarm handing
1:When unit fails or the wire controller
detects failure of communication with the
the outdoor units, the indicator blinks.
After all fault of the system and the wire
controller are eliminated, the indicator
stops blinking. The fault indicator and

● Fault alarm handling
1.When unit fails or the wired controller detects failure of communication with the outdoor units, the indicator
blinks. After all errors of the system and the wired controller are eliminated, the indicator stops blinking. The
fault indicator and the operation indicator share the same LCD.
2.Some errors will be auto cleared after the errors are cleared, and some error must press the “ALARM
CLEAR” button and then be cleared after the errors are cleared. The details can refer to the error code table.
If this type of error comes out frequently, then need to check and maintain the unit.
OVERVIEW OF WIRED CONTROLLER

1. Applicable range of supply voltage: Input voltage is AC 220V±10%, powered to wired controller by
attached power adapter.
2. Operating environment temperature of wired controller: -15℃~+43℃.
3. Operating RH of wired controller: RH40%~RH90%.
