Mode 1
(Climatic functioning with room/heat demand thermostat, variable set
point according to the outdoor temperature)
In this case the thermal module operates with a variable set-point de-
pending 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 climatic
109
mode (Par. 1 = 1).
Establishes the max. set-point at the minimum outdoor

temperature for climatic regulation
Establishes the minimum outdoor temperature to which

the maximum set-point can be associated for climatic
regulation
Establishes the minimum set-point at the maximum out-
21
door temperature for climatic regulation
Establishes the maximum minimum outdoor temperature
22
to which the minimum set-point can be associated for
climatic regulation
Limits the minimum value that can be assigned to the set-
23
point in heating mode (does not apply to heating mode 4).
Limits the maximum value that can be assigned to the set-
24
point in heating mode (does not apply to heating mode 4).

If the outdoor temperature sensor (accessory) is not detected
(not installed or damaged) the system provides a warning: no.

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.
