- The intervention of the Technical Assistance Service is required.
- The boiler is equipped with an auto-diagnostic system which,
based on the total number of hours in certain operating conditions,
can signal 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.
