V e r s i o n :
Not failure description
Low or no water flow (filter pump off or water valves closed) or flow
sensor error
Power supply excesses operation range
Excessive temp difference between inlet and outlet
water(Insufficient water flow protection)
Ambient temperature too high or too low protection
Anti-freezing reminder
Failure description
High pressure protection
Low pressure protection
3 phase sequence protection (three phase only)
Water outlet temp too high or too low protection
High exhaust temp protection
Evaporator overheat protection (only at cooling mode)
Controller communication failure
Water inlet temp sensor failure
Water outlet temp sensor failure
Gas exhaust temp sensor failure
Evaporator coil pipe temp sensor failure
Gas return temp sensor failure
Cooling coil pipe temp sensor failure
Ambient temp sensor failure
Cooling plate sensor failure
Current sensor failure
Restart memory failure
Failure of the compressor drive module / this is an activation of the
inverter board protection / it can be a unique activation, as the
inverter board is sensitive to fluctuations in the power supply or
peaks in the network /. Restart the heat pump by switching the
circuit breaker off and on (min. 60 seconds). If the error message is
repeated more than few times, contact your dealer.
PFC module failure
Compressor start failure
Compressor running failure
Inverter board over current protection
Inverter board overheat protection
Current protection
