cod. 3541U630 - Rev. 00 - 07/2020
Cure
Check the wiring or replace the fume probe
See fault F03
Check the connection to the water supply
Check the loading valve and valve control relay
Check for leaks in the heating system
Check the exchanger
Partially drain the system
Check the expansion vessel
Check the electrical system
Fill the system
Check the water pressure switch/pressure
transducer
Check the wiring or replace the sensor
Reconnect the external probe or disable the sli-
ding temperature
Check the correct positioning and operation of
the heating sensor
Check the correct positioning and operation of
the return sensor
Check the circulating pump
Vent the system
Partially drain the system
Check the filling valve and valve control relay
Check the expansion vessel
Check the correct positioning and operation of
the return and/or flow sensor
Check the correct positioning and operation of
the return sensor
Check the circulating pump
Vent the system
Check the water pressure sensor wiring
Check the water pressure sensor
Fill the system
Check the water pressure switch/pressure
transducer
Check the correct parameter setting
