Description
Utility pump flow
Source pump flow
Discharged primary circuit
Delta of input/output primary exchanger
temperature inconsistent to the
operating mode
Preallarme antigelo circuito primario
Exchange input water temperature over
the current operating mode limits
DHW primary/secondary circuit
insufficient exchange
Water charged DHW system (DHW)
System high temperature alarm
Phase sequence fault (only for 3 Ph
unit)
3 times E32/P6 protect
PFC module failure
high outdoor temperature in cooling
mode
high outdoor temperatur in DHW mode
high outdoor temperature in Heating
mode
low outdoor temperature in cooling
mode
LOW outdoor temperature in heating /
DHW mode
possible cause
system not under pressure - air must be let out, dirty sludge
remover, primary circulator stopped (mechanical error,
burned fuse)
Absence of water flow source side. Check pump flow.
Check pump operation. Verify flow switch activation.
System load low pressure
In SUMMER the outgoing temperature is higher than the
incoming temperature;
In WINTER the incoming temperature is lower than the
outgoing temperature;
Jammed refrigerating circuit inversion valve (check
solenoid).
INVERNO sbrinamento in condizioni anomale
(funzionamento fuori dai limiti)
ESTATE : bassa portata e set point troppo basso
operation out of limits
(Example: In SUMMER the system flow temperature is
higher than 25 °C; In WINTER the flow temperature is lower
than 20°C)
low flow on the DHW exchanger. Dirty exchanger.
sanitary water system with insufficient pressure
active supplementary heating element present
heating element thermostat with contact open
circulator pump stopped
lack of water in the system
Check the power supply cables to avoid phase loss.
Check the power supply cables sequence; change any two
cables sequence of the three power supply.
See E32/P6
The PFC module is broken, change a new PFC module.
