Mode 2
(Working on climatic mode with attenuation controlled by a
room/heat demand thermostat, variable set point accord-
ing to the outdoor temperature)
In this case the thermal module operates with a set-point
defined by the climatic curve (which can be set in the same
way as described in Mode 1) depending on outdoor tem-
perature. 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 2025.
In this mode the parameter 2028 defines by how many
degrees the set-point is decreased (attenuation) when the
room/ heat demand thermostat's contact is opened.
Par
No Description
2109 Defines the value of the set point calculated on
climatic mode (Par. 2001 = 1).
2019 Establishes the max. set-point at the minimum
outdoor temperature for climatic regulation
2020
Establishes the minimum outdoor temperature to
which the maximum set-point can be associated
for climatic regulation
2021 Establishes the minimum set-point at the maxi-
mum outdoor temperature for climatic regulation
2022
Establishes the maximum minimum outdoor tem-
perature to which the minimum set-point can be
associated for climatic regulation
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).
2025 Defines the temperature at which climatic regula-
tion is switched off
2028 Use the heating mode Par. 2001= 2 or 3. Defines
how many degrees the flow set point is lowered.

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 de-
creased (attenuation) by the value defined by the parame-
ter 2028 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.
Mode 4
(Set-point adjustment based on a 0-10V analogical input)
The maximum and minimum set-point values are defined
respectively by Par. 2111 and 2110.
Par
No Description
2110 Sets the minimum delivery temperature value in
heating mode (Par. 2001) = 4.
2111 Sets the maximum delivery temperature value in
heating mode (Par. 2001) = 4.
The operation set-point is adjusted on the basis of the fol-
lowing curve:

The maximum and minimum set-point values are defined
respectively by Par. 2111 and 2110.
When the input voltage value exceeds 1.5V, the demand is
triggered (at the minimum set-point).
For voltage values ranging from 2 to 10, the set-point varies
in a linear fashion from the minimum through to the maxi-
mum value. If the voltage is decreased from 10 to 2, the
set-point decreases in a linear fashion and maintains thee
minimum value between 2 and 1V. For values lower than 1
V the demand stops.
