Factory Settings
V.n)
The regulator is pre-configured for operation. However, the
user should adjust it to their specific needs. It is possible to
return to the factory settings at any time. When the option
'Factory Settings' is activated, all user settings for the boiler
are lost and replaced by the manufacturer's factory settings.
From this moment, the user's controller parameters may be defined once again.

This option enables the user to switch on or off the acoustic
sound signal when the alarm is activated.
Damping

This function is used to set the time after which the fan is
switched off if the boiler's temperature drops below the
damping threshold plus hysteresis 2°C. It means that if the
damping threshold is defined at 40ºC, this time is measured
not from the temperature of 40ºC but 38ºC.
