Double flow probe (shutdown E02)
Overheating control is performed by the double probe located on the flow pipe in place of
the classic contact safety thermostat.
When a temperature of 105°C is reached, the power supply to the gas valve cuts off
immediately and the E02 error message is displayed.
The alarm is reset via the reset b utton when the flow temperature reaches 90°C.
In the event of an E02 shutdown:
The fan performs a post-ventilation cycle at the ignition speed (P3) + 900 rpm until the flow
temperature falls below 90°C.
The pump performs a post-circulation cycle with the diverting valve in the heating position
if before the shutdown there was a heating, flow-return anti-freeze or chimney-sweep
request. There is a post-circulation cycle with the diverting valve on DHW if before the fault
there was a DHW or DHW anti-freeze request.
With P17=1 or P17=3, the multifunction relay performs a post-circulation cycle if it was
energised before the shutdown.
