Error category Error Description
Outdoor unit fault, Compressor discharge temperature too high
(Comp1) over 111 ºC. Low on ref gas, exp valve, pipework damage.
Outdoor unit fault, High pressure trip
Outdoor unit fault, Open phase on power supply. Check power on
each phase, inverter pcb, control pcb
Indoor unit fault, Ceiling panel incorrectly wired
Indoor unit fault, Condensate float switch opened
GHP - Water Heat exch low temp (frost protection) fault
Indoor unit fault, Fan DC motor fault
Input from leak detector (If fitted)
Refrigerant loss, high discharge temp and EEV wide open and low
compressor current draw.
Outdoor unit fault, Open phase on compressor power supply
Outdoor unit fault, Compressor discharge temperature too high
(Comp2) over 111 degC. Low on ref gas, exp valve, pipework
damage.
Outdoor unit fault, By-pass valve failure
Outdoor unit fault, 4 way valve failure, i/door temp rises in cooling or
fills in heating. Check wiring, coil, pcb output, valve operation.
Ref gas, high temp/pressure fault, heat exch temp high C2, 55-60
degC, cooling over-load, sensor fault.
Outdoor unit fan motor fault, fan blade jammed, check connections,
does fan turn freely, motor resistance 30-40ohm on each pair, no
fan fault, yes pcb fault.
Outdoor unit fault, Compressor overcurrent - check winding
resistance, Inverter failure - check internal resistance term HIC + &
- to UVW 200-300Kohm or more
Outdoor unit fault, Inverter circuit fault - Motor-current Detection
Circuit (MDC) fault, check comp windings, sensors C1 & TS, if ok
possible pcb failure.
Indoor unit fault, System controller detected fault on sub indoor unit
Simultaneous operation multi control fault, Group controller fault
