**ATTENTION!
In case of removal / deactivation of the external temperature probe of the boiler, during the operation of
the thermostat, it will be necessary to restart the control unit to allow it to detect the new situation.
***ATTENTION!
This data is valid only if the boiler is not equipped with an external probe and if the product has not been
connected to the application.

Should errors occur in the boiler, they signal a code visible on the touch screen of the thermostat which can begin with the
letter E or the letter C.
If the error code begins with the letter E, it must be converted to binary format and interpreted following the table below.
Note:
If you have difficulty converting, please consult your trusted installer.
