run until unit stops.
EV01=work by regulation, water pump will be ON
when compressor is ON, will be OFF when compressor
is OFF.
4 way valve control (NO3)
4 way valve is OFF on below conditions. It is ON at
other conditions.
1.) Heating mode, hot water mode, or h hot
water mode
2.) Producing hot water on c hot water mode.
Auxiliary Electric heater or boiler control (NO4)
Auxiliary heater or boiler only could be switched on
when all of conditions below are met.
1.) Heating mode running
；
2.) Compressor has run over 300s
3.) OT≤ST07
；
4.) ST ≤ST02-ST04-1
；
Auxiliary heater or boiler only could be switched off
when any of conditions below is met.
1.) A/C flow switch cut off over 2s
；
2.) ST≥ST02-ST04
；
3.) unit is switched off
4.)ST sensor probe trouble
Auxiliary heater or boiler is switched on during
defrosting period.
Hot water priority:
· When unit is heating, if there is a call for hot water
, it start 3 way valve at once and turn to hot water
mode directly. It will revert back to heating mode
after hot water reach set temperature.
· When unit is cooling, if there is a call for hot water ,
it stops compressor first and then start at hot water
mode , it stops compressor again when hot water
reach set temperature before it revert back to cooling
mode.
Crankcase heater running control (N05)
When all of conditions below are met, compressor
crankcase heater is switched on
1.) Compressor is OFF
；
2.) OT≤SF26
W hen any of conditions below is met, compressor
crankcase heater is switched off
1.) Compressor is ON
；
2.) OT≥SF26+1
3 way valve control (NO7)
1.) 3 way valve is OFF when unit is cooling or
heating .3 way valve is ON when unit is producing
domestic hot water.
2.) If unit is defrosting on heating mode, 3 way valve
is off at first, if ST≤AR01 and last 2 seconds, 3
way valve is switched ON. If ST≤AR01 and last 2
seconds again, it will report AL03 , exit defrosting
and return to heating.
3.) If unit is defrosting on hot water mode, 3 way valve
is on at first, if ST≤AR01 and last 2 seconds, 3
way valve is switched OFF. If ST≤AR01 and last 2
seconds again, it will report AL03 , exit defrosting
and return to product hot water.
Hot water heater control (NO8)
Hot water electric heater in the water tank could be
switched on in periodic time (ST26) to a pre-set hot
water temperature (ST27) to prevent logionnella
.Factory default setting of ST26=0, ST27= 65
℃
.

；
2. Heating or DHW mode running
3. Ambient temperature≤DF15
When any of conditions below is met, de-icing heater is
switched off
