COMMISSIONING AND MAINTENANCE
Parameter 190 (installer level)
Each building has its own thermal characteristics, therefore
the time needed to set up the heating system can differ even
among buildings located in the same area, with the same ex-
ternal temperature.By using this parameter it is possible to
modify the heating system reactivity adapting its response to the
thermal characteristics of the building and thus optimising the
environmental comfort.Modifying the setting of this parameter
(0-100%) increases or decreases the speed at which the deliv-
ery temperature changes according to the external temperature
change.Setting a higher value will improve the building insula-
tion. Example:
− 0%: The delivery temperature changes quickly when the
external temperature changes.
− 100%: The delivery temperature changes slowly when the
external temperature changes.
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.
Parameter 185 (installer level)
The parallel translation of the climatic curve is used to change the
delivery temperature evenly for the entire outdoor temperature
scale.Changing the value of this parameter corrects the climat-
ic curve if the ambient temperature is too high (set a negative
value) or too low (set a positive value). If the room has an Open
Therm thermostat, this value is not taken into consideration.This
parameter allows the user to directly and easily increase (posi-
tive value) or decrease (negative value) the delivery temperature
to the heating system and thus the ambient temperature.

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.
