FUNCTiONaL bUTTONS
y
If pressed once or more than once for at least 1 second
during normal operation, this button allows the user
to change the boiler operating mode in a cyclical se-
quence (stand-by – summer – Winter).If the boiler is
experiencing a fault which can be reset, it allows boiler
operation to be unblocked.
r
during normal operation, pressing the button displays
the domestic hot water set point which can be betwe-
en 10 and 60°C. In "parameter setting", the user can
scroll through the parameter index (decreasing) by
pressing this button.
t
during normal operation, pressing the button di-
splays the heating set point which can be between 20
and 80°C. In "parameter setting", the user can scroll
through the parameter index (increasing) by pressing
this button.
<
during normal operation, pressing this button allows
the user to reduce the heating or dHW set point on
the basis of the selection made previously. If there is
a Remote Control (open therm), after having selected
the heating button, the user can modify the incline of
the climatic curve (decreasing it) by pressing the but-
ton (-). In "parameter setting/display", the user can
modify the parameter setting or value (decreasing) by
pressing this button.

a Remote Control (open therm), after having selected
the heating button, the user can modify the incline of
