9.3.3 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
[A.3.1.1.1] Main > LWT setpoint
mode
Weather dep. OR WD/scheduled
Additional zone – Heating
[A.3.1.2.1] Additional > LWT
setpoint mode
Weather dep. OR WD/scheduled
Tank
[A.4.6] Domestic hot water (DHW)
> SP mode
Weather dep.
To change the weather-dependent curve
Zone Go to …
Main zone – Heating [7.7.1.1] Main > Set weather-
dependent heating
Additional zone – Heating [7.7.2.1] Additional > Set
weather-dependent heating
Tank [A.4.7] Domestic hot water (DHW)
> Weather-dependent 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
The following table describes how to fine-tune the weather-dependent curve of a
zone or tank:
