RED LED GREEN LED FAULT DESCRIPTION OF ALARM TYPE
E021 ON ion alarm
These are temporary alarms that if they occur 6 times in an hour they become denitive; the E097 alarm is displayed and
is followed by post-purging for 45 seconds at the fan's maximum speed.
It is not possible to release the alarm before the end of the post-purging unless the boiler's power supply is switched off.
E022 ON ion alarm
E023 ON ion alarm
E024 ON ion alarm
E067 ON ion alarm
E088 ON ion alarm
E097 ON ion alarm
E085 ON incomplete combustion
These are temporary alarms that if they occur several times in an hour they become denitive; the last error to occur is
displayed and is followed by a post-purging of 5 minutes at the fan's maximum speed.
It is not possible to release the alarm before the end of the post-purging unless the boiler's power supply is switched off.
E094 ON incomplete combustion
E095 ON incomplete combustion
E058 ON mains voltage fault
These are temporary faults that restrict the ignition cycle.
E065 ON current modulation alarm
E086 ON ue gases obstruction alarm Temporary fault signalled during pre-purging. Post-purging is maintained for 5 min at maximum fan speed.
