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 "10.5.4 Using weather-dependent
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
"10.5.4 Using weather-dependent
Define the weather-dependent curve with these two setpoints:
▪ Setpoint (X1, Y2)
▪ Setpoint (X2, Y1)
Example
Y2
Y1
X1
Item
X1, X2 Examples of outdoor ambient temperature
Y1, Y2 Examples of desired tank temperature. The icon corresponds to the
heat emitter for that zone:
▪ : Domestic hot water tank
Go through the temperatures.
Change the temperature.
Go to the next temperature.
Confirm changes and proceed.
