Heating curve displacement
The curve shift (offset) modifies the flow
temperature in a general and even manner over the
full range of outdoor temperature. In other words,
the shift should be corrected when the room
temperature is generally too high or too low.
Heating curve adaptation
Adaptation enables the controller to automatically
adapt the heating curve to the present conditions.
This correction may only be activated or
deactivated.
In the latter case, there is no need to correct the
slope and shift.
Information:
To ensure operation, the following requirements
must be met:
-
A room sensor must be connected.
-
The "room influence" parameter must be
set between 1 and 99.
-
The reference room (where the room
sensor is installed) must not contain adjusted
thermostatic valves. If present in the room, these
valves must be fully open.
-
Operation of this function requires an
adaptation period which can take more or less time
(approx. 1 week) depending on weather conditions
and on the stability of the room temperature
setpoint.

Summer/winter heating limit
The summer/winter heating limit switches the heating
on or off through the year according to the
temperature ratio. Changeover is performed
automatically when in automatic mode and thus
avoids the user having to turn the heating on or off.
Changing the input value makes the respective
annual periods (summer/winter) shorter or longer.
-
If the value is increased:
Changing to winter operating mode is advanced,
changing to summer mode is delayed
-
If the value is decreased:
Changing to winter mode is delayed; changing to
summer mode is advanced.
Information:
This function does not work in "Continuous Comfort
temperature" mode. (Sunlight)
The controller displays "ECO".
The outdoor temperature is attenuated to take the
building's dynamics into account.
