Setting the heating parameters
The parameter 1establishes the thermal module's various heat-
ing operation modes.
Mode 0
(Operation with room thermostat/heat demand and fixed heat-
ing setpoint)
In this mode, the thermal module operates with a fixed set-
point (controlled by the parameter3) based on whether the
room/heat demand thermostat's contact is closed or not.
The set-point value can be entered directly, without entering in
the parameter list, by accessing the “CH” menu in the following
way:
Press MENU and select "Central heating" using the
▲
/
▼
keys.
Press the
●
key to confirm.

the set point can be set within a minimum and maximum val-
ue as indicated respectively on Par. 23 and 24 as shown in the
figure.
The outdoor temperature sensor (accessory) is not required and
if connected the outdoor temperature that is measured does
not influence the setpoint that has been set.
