outside the admissible range (equivalent to short circuit)
Return sensor shorted Error 43
The return sensor has detected a temperature
outside the admissible range (equivalent to short circuit)
Return sensor open Error 44
The return sensor has detected a temperature
outside the admissible range (equivalent to short circuit)
Errors with safety block
The table below lists the errors/faults that generate a Safety Block.
To restore normal operating conditions:
- Disconnect the electrical and gas power supplies from the appliance
- Eliminate the cause of the fault
- Restart the appliance.
Errors with safety stop
The table below lists the errors/faults that generate a Safety Stop.
