Weather-dependent curve
To be able to compensate for differences in temperature, the unit relies on its
weather-dependent curve. This curve defines how much the target temperature of
the tank must be at different outdoor temperatures. Because the slope of the
curve depends on local circumstances such as climate and the insulation of the
house, the curve can be adjusted by an installer.
Types of weather-dependent curve
There are 2 types of weather-dependent curves:
▪ 2-points curve
▪ Slope-offset curve
Which type of curve you use to make adjustments, depends on your personal
preference. See
"5.8.4 Using weather-dependent curves" [ 4 33].
Availability
The weather-dependent curve is available for:
▪ Tank (only available to installers)
INFORMATION
To operate weather-dependent, correctly configure the setpoint of the tank. See
"5.8.4 Using weather-dependent curves" [
4
33].
5.8.2 2-points curve
Define the weather-dependent curve with these two setpoints:
▪ Setpoint (X1, Y2)
▪ Setpoint (X2, Y1)
Example
Y1
Y2
X1 X2
Item Description
X1, X2 Examples of outdoor ambient temperature
Y1, Y2 Examples of desired tank temperature. The icon corresponds to the
heat emitter for that zone:
