Setting the heating parameters

The parameter 2001establishes the thermal module's various heating
operation modes.
Mode 0
(Operation with room thermostat/heat demand and fixed heating set-
point)
In this mode, the thermal module operates with a fixed set-point (con-
trolled by the parameter0003) based on whether the room/heat de-
mand thermostat's contact is closed or not.
The set point value can be set directly without entering the parameter
list as indicated on Par. "USER navigation MENU".
the set point can be set within a minimum and maximum value as
indicated respectively on Par. 2023 and 2024 as shown in the figure.
The outdoor temperature sensor (accessory) is not required and if
connected the outdoor temperature that is measured does not influ-
ence the setpoint that has been set.
The parameters regulating such temperature are:
Par.
Description
No.
Sets the desired flow temperature with heating mode.
0003
Active for the heating mode Par. 2001 = 0 o 3
2023 Limits the minimum value that can be assigned to the set-
point in heating mode (does not apply to heating mode 4).
2024 Limits the maximum value that can be assigned to the set-
point in heating mode (does not apply to heating mode 4).

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
2109
mode (Par. 2001 = 1).
Establishes the max. set-point at the minimum outdoor
2019
temperature for climatic regulation
Par.
Description
No.
Establishes the minimum outdoor temperature to which
2020 the maximum set-point can be associated for climatic
regulation
Establishes the minimum set-point at the maximum out-
2021
door temperature for climatic regulation
Establishes the maximum minimum outdoor temperature
2022 to which the minimum set-point can be associated for
climatic regulation
Limits the minimum value that can be assigned to the set-
2023
point in heating mode (does not apply to heating mode 4).
Limits the maximum value that can be assigned to the set-
2024
point in heating mode (does not apply to heating mode 4).
2025 Defines the temperature at which climatic regulation is
switched off
Display on climatic mode
The demand is activated when the room/heat demand thermostat's
contact is closed provided that outdoor temperature does not exceed
the value set by the parameter 2025.
if the outdoor temperature is higher than the one set on parameter
2025 , the burner is stopped even if there is a heat demand.
b
If the outdoor temperature sensor (accessory) is not detected
Tset max (°C)
(not installed or damaged) the system provides a warning: no.

The presence of the warning does not stop the thermal module
