Constant temperature mode (F01 = 0)
Heat by compressor (F02 = 0)
If (water temperature)
≥ (se F03), and the compressor has stopped for F06, the compressor starts cooling.
If (water temperature)
≤ (setpoint), the compressor de-energized.
If (water temperature)
≤ (setpoint-F03), and the compressor has stopped for F06, the compressor starts heating.
If (water temperature)
≥ (setpoint), the compressor de-energized.
Control sequence: Compressor on, fan will be on after 10 seconds. Compressor off, fan will be off after 5 seconds.
Heating cooling change sequence: the compressor will be energized 15 seconds after 4-way valve is set.
Heat by electrical heater (F02 = 1)
If (water temperature)
≥ (se F03), and the compressor has stopped for F06, the compressor energized.
If (water temperature) ≤ (setpoint), the compressor de-energized.
If (water temperature) ≤ (setpoint-F03), the heater energized.
If (water temperature)
≥ (setpoint), the heater de-energized.
Control sequence: Compressor on, fan will be on after 10 seconds. Compressor off, fan will be off after 5 seconds.
Defrost (F02 = 0, and under heating mode)
Intelligent defrost
If (pipe temperature)
≤ F07, and the compressor has been energized for F10, start defrost.
If (pipe temperature)
≥ F08, or (the defrosting time) ≥ F09, stop defrost.
Periodic defrost
Without defrost sensor, or when defrost sensor fails, the controller will defrost periodically.
When the compressor has been energized for F10, start defrost.
When defrosting time reaches F09, defrost ends.
Defrost procedure
Compressor stops
→valve switches after 30 seconds→compressor starts for defrost after 30 seconds→compressor stops
when F08 or F09 condition meets
→valve switches after 30 seconds→start compressor heating after 30 seconds.
Fan stops during defrosting.
Forced defrost (F02 = 0, under heating mode)

depressed simultaneously for one second to enter into forced defrosting.
* Forced defrosting works the same way as periodical defrost.
* Once launched forced defrost, it will not stop, till the full process finished.
* Fan stops during forced defrosting.

depressed simultaneously for 6 seconds, there will be 3 short beeps and 1 long beep,
and the compressor will be energized.
The controller will keep working as the set of F01 for 90 seconds, then exit the status.

to switch to online, the pump keeps off!
* External alarm does not influence the pump status.
External alarm input
F12 = 0, disable external alarm function.
F12 = 1, when short for F13 time, alarming.
F12 = 2, when open for F13 time, alarming.
During alarming, all outputs except pump de-energized, buzzing, E3 displays, power lamp blinking.
Delay protection for compressor
Every time, the power supplied, the compressor is possible to be energized after F06 time.
Every time, the compressor is de-energized, it is possible to be energized after F06 time.
Auto restart
When power supply loses, and then come back, the controller will work in the same status as that before power loses.
Calibration
By setting F04/F05, we can compensate the error of the sensors.
Warning for sensor failure
When water sensor fails, display E1, compressor/valve or heater/fan will be de-energized, beeping, OnOff lamp blinking.
When pipe sensor fails, display E2.
