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-

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).

The demand is activated when the room/heat demand thermo-
stat's contact is closed provided that outdoor temperature does
not exceed the value set by the parameter 25.
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-
er-friendly way.

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.

Mode 2
(Working on climatic mode with attenuation controlled by a
room/heat demand thermostat, variable set point according to
the outdoor temperature)
In this case the thermal module operates with a set-point de-
fined by the climatic curve (which can be set in the same way as
described in Mode 1) depending on outdoor temperature. Heat
demand is actioned independently from whether the room/
heat demand thermostat's contact is closed and stops only
when the outdoor temperature is greater than the one defined
by the parameter 25.
In this mode the parameter 28 defines by how many degrees
the set-point is decreased (attenuation) when the room/ heat
demand thermostat's contact is opened.

109

Establishes the minimum outdoor temperature to

Establishes the minimum set-point at the maximum

Establishes the maximum minimum outdoor tempera-

Mode 3
(Continuous fixed set-point operation with attenuation con-
trolled by room/heat demand thermostat)
In this mode the fixed set-point is adjusted in the same way
as described for Mode 0. The difference consists in the fact that
the demand is always active and the set-point is decreased (at-
tenuation) by the value defined by the parameter 28 when the
room/heat demand thermostat's contact is opened.

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 that control this mode are the following:
