Working Mode
Press to switch between “AUTO” and “SAVE” working mode.
“AUTO” mode: always heating according setting. “SAVE” mode: only heating within three set periods.
When “Auto restart function” is disabled (U80 = 0), it will be “AUTO” mode after power supplied.
Clock Setting
Press key, the hour digits will blink, press key to set hour.
Press key again, minute digits will blink, press key to set minute.
Press key to exit.

The maximum periods are 3. Every period has an on-time and an off-time.
If one period’s on-time = off-time =0, this period will be shut off.
If one period’s off -time is earlier than its on-time, this off-time is the time of the 2nd day.

Control Function
Temperature Control
When T-water ≤SP –U01, start heating. When T-water ≥SP, stop heating.
Heating start procedure:
Pump is on; 30 seconds later, outdoor fan is on, valve acts; 30 seconds later, compressor is on.
Heating stop procedure:
Compress is off; 30 seconds later, outdoor fan is off, valve acts; 30 seconds later, pump is off.
Note: the four-way valve works according to U34.
Aux Electrical HeaterControl
When T-outdoor ≤U03, and T-water ≤ SP – U01, heater is on.
When T-outdoor ≥U03 + 3℃, or T-water ≥SP, heater is off.
If compressor is on, the heater will be on 10 seconds later when condition meets.
If compressor is off, the heater willbe off 10 seconds later.
Note: Heater will be on during defrosting.
Water Ventilation Pump Control
The pump will be on 60 seconds before the compressor is on, be off 60 seconds after the compressor is off.
The pump will always be on during defrosting.
If there is no water flowing for 10 seconds, stop compressor and heater, and keep warning.
When the water flowing restores, restore the systemcontrol
Avoid Freezing in Winter
In offline standby status:
When T-outdoor ≤2℃, start anti-freezing pumping, the pump run 3 minutes for every 30 minutes.
When T-outdoor ≥ 3℃, stop thisanti-freezing protection pumping.
Auto Defrost
Start auto defrosting: When compressor has been running for U30, and if T-pipe ≤U31, start defrosting.
Compressor and outdoor fan stop; 55 seconds later, valve acts; 5 seconds later, start compressor.
Stop defrosting: When T-pip ≥U32, or the compressor has been running for U33, stop defrosting:
Stop compressor; 55 seconds later, valve acts; 5 seconds later, start heating control.
Defrost after turning the systemonline: When turn online, if the T-pipe ≤U31, defrost 1st.
Timer Defrost
If pipe sensor fails，and the compressor has been running for U30,
If outdoor sensor isok, and T-outdoor ≤ 3℃, start defrosting.
If outdoor sensor fails,start defrosting.
Exhaustion Protection forOver Hot
If U50 = 0, no exhaustion protection.
If U50 = 1 or 2:
When T-exhaustion ≥ U51 + 10℃, stop heating and start alarming.
When T-exhaustion ≤U51 - 10℃, stop protection and alarming, heating again.
If U50 = 2: When T-exhaustion ≥ U51, stop fan.
High/Low Pressure Warning and Protection
When compressor running, if the high/low pressure is effective for 15 seconds, start pressure protection:
Stop compressor, until the high/low pressure is not effective.
If the pressure protection occurs 3 times within an hour, the controller willbe in machine protection mode:
Never start heating again, until remove power supply and supply power again.
When compressor has just started, the high/low pressure will not be in checking for 3 minutes.
Note: the high/low pressure mode is set in U60.

CompressorDelay Protection
After power supplied, the compressor can start after 3 minutes.
After compressor stops, it can re-start 3 minutes later.
Water Sensor Failure Warning
When this sensor fails, system stops heating, until the sensor becomes well again.
Refrigerant Filling
In online status, keep depressed simultaneously for 3 seconds, display “AdF”, start refrigerant filling.
There will be no pressure and exhaustion alarming during the filling status.
Keep depressed simultaneously for 3 seconds, exit the filling status.
If the filling status has been for 15 minutes, it will exit automatically.
The action: pump on,fan on 30 seconds later, valve acts (acts oppositely to the U34 setting), compressor on
30 seconds later.
Auto Restart
If U80 = 0, the controller will be in offline status after power supplied.
If U80 = 1, the controller will be the same status as that before the power supply lost.
Restore to Factory Settings
Restore password:
Press keys simultaneously, display “UnL”, the password will be restored to “11”3 seconds later.
Restore all parameters:
Press keys simultaneously, all parameters, including password, will be restored to factory settings.
Wiring Diagram
Attention
Set U34 correctly, otherwise systemdoes not work correctly.
The real clock can only keep running correctly for 72 hours after power supply loses.
All sensorsmust be installed at correct position.
Do not plug in/out panel bundle with power supplied.
Panel should be installed indoors, instead of outdoors.
