Item Description
a WD curve before changes.
b WD curve after changes (as example):
▪ When slope is changed, the new preferred
temperature at X1 is unequally higher than the
preferred temperature at X2.
▪ When offset is changed, the new preferred
temperature at X1 is equally higher as the preferred
temperature at X2.
c Slope
d Offset
e Selected weather-dependent zone:
▪ : Main zone or additional zone heating
▪ : Main zone or additional zone cooling
▪ : Domestic hot water
X1, X2 Examples of outdoor ambient temperature

Examples of desired tank temperature or leaving water
temperature. The icon corresponds to the heat emitter
for that zone:
▪ : Underfloor heating
▪ : Fan coil unit
▪ : Radiator
▪ : Storage tank
Possible actions on this screen
Select slope or offset.
Increase or decrease the slope/offset.
When slope is selected: set slope and go to offset.
When offset is selected: set offset.
Confirm changes and return to the submenu.
7.3.4 Using weather-dependent curves
Configure weather-dependent curves as following:
To define the setpoint mode
To use the weather-dependent curve, you need to define the correct
setpoint mode:
Go to setpoint mode … Set the setpoint mode to …
Main zone – Heating
[2.4] Main zone > Setpoint
mode
WD heating, fixed cooling
OR Weather dependent
Main zone – Cooling
[2.4] Main zone > Setpoint
mode
Weather dependent
Additional zone – Heating
[3.4] Additional zone >
Setpoint mode
WD heating, fixed cooling
OR Weather dependent
Additional zone – Cooling
[3.4] Additional zone >
Setpoint mode
Weather dependent
Tank
[5.B] Tank > Setpoint mode Restriction: Only available to
installers.
Weather dependent
To change the type of weather-dependent curve
To change the type for all zones (main + additional) and for the tank,
go to [2.E]
Main zone > WD curve type .
Viewing which type is selected is also possible via:
▪ [3.C]
Additional zone
>
WD curve type
▪ [5.E] Tank > WD curve type
Restriction: Only available to installers.
To change the weather-dependent curve
Zone Go to …
Main zone – Heating [2.5] Main zone > Heating WD
curve
Main zone – Cooling [2.6] Main zone > Cooling WD
curve
Additional zone – Heating [3.5] Additional zone >
Heating WD curve
Additional zone – Cooling [3.6] Additional zone >
Cooling WD curve
Tank Restriction: Only available to
installers.
[5.C] Tank > WD curve
INFORMATION
Maximum and minimum setpoints
You cannot configure the curve with temperatures that are
higher or lower than the set maximum and minimum
setpoints for that zone or for the tank. When the maximum
or minimum setpoint is reached, the curve flattens out.
To fine-tune the weather-dependent curve: slope-offset curve
The following table describes how to fine-tune the weather-
dependent curve of a zone or tank:
