Cause
If room central heating or domestic hot water production is
requested, (when the boiler is paired with a storage tank
unit) the boiler does not switch on within the preset time.
Upon appliance commissioning or after extended down-
time, it may be necessary to eliminate the block.
During normal operation, if a fault causes excessive over-
heating internally, the boiler goes into overheating block.
During normal operation, if a fault causes excessive flue gas
overheating, the boiler blocks.
The P.C.B. detects a fault on the gas valve supply. Check its
connection. (the anomaly is detected and displayed only in
the event of a request). Once it has been established that the
fault is not related to the gas valve, the P.C.B. must be re-
placed if the fault does not disappear after pressing the Re-
set button.
The board detects an anomaly on the flow NTC probe.
