High pressure protection (Code: AL36)
It does not scan high pressure on defrosting period and within 10 seconds after defrosting stop.
At other time if
B12(HPS)≥AR15 , the compressor is off ,after 5 seconds delay, the fan motor will
be stopped, PWM water pump will run as EV06, other parts will keep its original state. A
continuous blink code AL36 will appear on the LCD, until
B12(HPS) ≤AR15-AR16
, the unit will
turn to its normal work.
High pressure protection (serious) (Code: AL33)
If in 24 hours time, AL36 happening times is over AR07, manual reset alarm AL33 will happen,
the compressor is off, 5 seconds later, fan motor will be stopped, PWM water pump will run as
EV06, other parts will keep its original state. A continuous blink code AL33 will appear on the
LCD.
Anti-freeze protection (Code : AL26)
When water pump is off and ambient temperature
≤
SF06, water pump will be switched on in
every AR11 interval ,PWM is EV05. 180 seconds later,
If outlet water temperature
＞ SF08, switch off water pump.
If outlet water temperature
≤
SF08 and unit is off state, if water flow switch is closing, A/C
auxiliary heater is switched on .If water flow switch is opening, it does not switch on A/C
auxiliary heater and displays AL26 . Until outlet water temperature
≥ SF08+SF09, it switches off
A/C auxiliary heater , 10 seconds later, switches off water pump. If the units is switched on, it will
be on.
When the unit is on standby state at hot water mode, if ambient temperature
≤
SF06, water pump
and 3 way valve will be switched on in every AR11 interval ,PWM is EV05. It will switch water
pump when outlet water temperature>SF08.
If outlet water temperature sensor is out of order, inlet water temperature sensor will be replaced
as antifreeze water temperature reference. If inlet water temperature sensor is out of order too,
water pump will continue to run until OT
＞
SF06+SF07
Display offline - Wired remote control and main board communication
trouble.
After this trouble happen, unit still can work normally but the wired remote control
can not be used to operate the unit.
