No.
Sets the desired flow temperature with heating mode.

Active for the heating mode Par. 1 = 0 o 3
Limits the minimum value that can be assigned to the
23 set-point in heating mode (does not apply to heating
mode 4).
Limits the maximum value that can be assigned to the
24 set-point in heating mode (does not apply to heating

Mode 1
(Climatic functioning with room/heat demand thermostat, vari-
able set point according to the outdoor temperature)
In this case the thermal module operates with a variable set-
point depending on outdoor temperature based on a climatic
curve defined by the following parameters:
Par.
Description
No.
Defines the value of the set point calculated on climat-
109
ic mode (Par. 1 = 1).
Establishes the max. set-point at the minimum out-
19
door temperature for climatic regulation
Establishes the minimum outdoor temperature to
20 which the maximum set-point can be associated for
climatic regulation
Establishes the minimum set-point at the maximum
21
outdoor temperature for climatic regulation
Establishes the maximum minimum outdoor tempera-
22 ture to which the minimum set-point can be associat-
ed for climatic regulation
Limits the minimum value that can be assigned to the
23 set-point in heating mode (does not apply to heating
mode 4).
Limits the maximum value that can be assigned to the
24 set-point in heating mode (does not apply to heating
mode 4).
Defines the temperature at which climatic regulation is

switched off
The demand is activated when the room/heat demand thermo-
Tset max (°C)
stat's contact is closed provided that outdoor temperature does
not exceed the value set by the parameter 25.
Setpoint
if the outdoor temperature is higher than the one set on param-
eter 25 , the burner is stopped even if there is a heat demand.
The climatic curve can also be adjusted in a simpler, more us-
Tset min (°C)
er-friendly way.
Enter the "CH" menu. The following display will appear:

If the outdoor temperature sensor (accessory) is not detect-
ed (not installed or damaged) the system provides a warn-
ing: no. 202
The presence of the warning does not stop the thermal
module allowing a heat request to be carried out at the
maximum setpoint set on the climatic regulation.
