3 2 3 Setting the heating parameters

The parameter 2001establishes the thermal module's vari-
ous heating operation modes.
Mode 0
(Operation with room thermostat/heat demand and fixed
heating setpoint)
In this mode, the thermal module operates with a fixed set-
point (controlled by the parameter0003) based on whether
the room/heat demand 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 influence the setpoint that has been set.
The parameters regulating such temperature are:
Par

No
Sets the desired flow temperature with heating
0003 mode. Active for the heating mode Par. 2001 = 0
o 3
Limits the minimum value that can be assigned to
2023 the set-point in heating mode (does not apply to
heating mode 4).
Limits the maximum value that can be assigned
2024 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 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
2109
climatic mode (Par. 2001 = 1).
Establishes the max. set-point at the minimum

outdoor temperature for climatic regulation
Par
Description
No
Establishes the minimum outdoor temperature to
2020 which the maximum set-point can be associated
for climatic regulation
Establishes the minimum set-point at the maxi-
2021
mum outdoor temperature for climatic regulation
Establishes the maximum minimum outdoor tem-
2022 perature to which the minimum set-point can be
associated for climatic regulation
Limits the minimum value that can be assigned to
2023 the set-point in heating mode (does not apply to
heating mode 4).
Limits the maximum value that can be assigned
2024 to the set-point in heating mode (does not apply
to heating mode 4).
Defines the temperature at which climatic regula-
2025
tion is switched off
Display on climatic mode
The demand is activated when the room/heat demand ther-
mostat's contact is closed provided that outdoor tempera-
ture 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 (not installed or damaged) the system pro-
vides a warning: no. 202
The presence of the warning does not stop the thermal
Tset max (°C)
module allowing a heat request to be carried out at the
maximum setpoint set on the climatic regulation.
