4.2 Power failures
The remote control provides for storing the operation mode and calendar updating (day, hour and minutes) in case of a power failure. The charging reserve is 5 hours minimum (guar-
anteed only if the remote control remains electrically fed for at least 1 hour).
Otherwise, it is necessary to reset the current day, hour and minutes and then the operation mode.
4.3 Diagnostics
The remote control continuously monitors boiler status and signals any faults by activating the alarm icon and an error code on the display: for the description of the fault, refer to the
boiler documentation.
There are faults that cause permanent shutdowns (indicated with the letter "A" and the symbol ): to restore operation, just press the button .
Other faults cause temporary shutdowns (indicated with the letter "F") which are automatically reset as soon as the value returns within the boiler's normal operating range.
4.4 Room temperature probe fault
If the Remote Control room temperature probe is faulty, the display activates fault E92 and the symbol . Heating is turned off.
4.5 External temperature probe fault
In Sliding Temperature mode, if the external temperature probe (optional) is faulty, the display activates fault E93 and the symbol . The adjustment temperature becomes fixed at
the "Heating temperature adjustment" value. To eliminate the fault, restore the external probe or disable the Sliding Temperature adjustment.
4.6 Restoring factory settings
Attention! With this procedure all the Remote Control parameters will be reset to the factory value. It will therefore be necessary to repeat the procedure for the automatic weekly
program and reset the user parameters.
Press the buttons / together for 10 seconds: only the message RE blinking is displayed. Releasing the buttons at any time before the end of the 10 seconds interrupts
the procedure. After the reset, the Remote Control activates all the symbols on the display.
