11.5.4 Using weather-dependent curves

Installer reference guide

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 ...
Main zone – Heating
[2.4] Main zone > Setpoint mode
Main zone – Cooling
[2.4] Main zone > Setpoint mode
Additional zone – Heating
[3.4] Additional zone > Setpoint
mode
Additional zone – Cooling
[3.4] Additional zone > Setpoint
mode
To change the type of weather-dependent curve
To change the type for all zones (main + additional), 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
To change the weather-dependent curve
Zone
Main zone – Heating
Main zone – Cooling
Additional zone – Heating
Additional zone – Cooling
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. 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:
Set the setpoint mode to ...
