1. Display only of the icon
The appearance of the
icon indicates that an operation fault has
been diagnosed and the boiler will attempt to resolve it autonomously
(temporary stop).
If the boiler does not resume normal operation, there are two possi-
ble display cases.
Case A
disappears, and the RESET icon appears along with a different
alarm code.
In this case, proceed as described in point 2.
CASE A
temporary
fault
definitive
fault
Case B
the RESET icon will appear along with a different alarm code, togeth-
er with the
.
In this case, proceed as described in point 3. In this case, proceed
as described in point 2.
CASE B
temporary
fault
definitive
fault
Case C
Together with the
, alarm code 91 will appear (see description be-
low).
The intervention of the Technical Assistance Centre is required.
The boiler is equipped with an auto-diagnostic system which, based
on the total number of hours in certain operating conditions, can sig-
nal the need to clean the primary exchanger (alarm code 91).
Once the cleaning operation has been completed, reset to zero the
total hour meter with special kit supplied as an accessory following
procedure indicated below:
- Switch off the power supply
- Remove the electric casing by means of the screws and fixing
hooks
- Extract the connector J13 (see wiring diagram)
- Power up the boiler and wait for alarm 13 to appear on the display
- Disconnect the power supply and reconnect connector J13
- Refit the electric casing and restore the boiler's function.
NOTE: the meter resetting procedure should be carried out after
each in-depth cleaning of the primary exchanger or if this latter is
replaced.
2. Display only of the RESET icon
Press the
key to restore operation. If the boiler performs the fir-
ing procedure and resumes normal operation, the stoppage can be
attributed to a chance situation.
Repeated lockouts require the intervention of the Riello Techni-
cal Assistance Centre.
3. Display of the RESET and
icons
The intervention of the Riello Technical Assistance Centre is required.
