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.

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 …

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 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 the tank:

offset:
At regular outdoor
temperatures …
