10.3.3 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/Cooling
[A.3.1.1.1] Main > LWT setpoint
mode
Weather dep. OR WD/scheduled
Additional zone – Heating/Cooling
[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
