Advantage
Weather-dependent operation reduces energy consumption.
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 temperature of the
tank or leaving water must be at different outdoor temperatures. Because the
slope of the curve depends on local circumstances such as climate and the
insulation of the building, the curve can be adjusted by an installer or user.
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 curves" [
4
161].
Availability
The weather-dependent curve is available for:
▪ Main zone - Heating
▪ Main zone - Cooling
▪ Additional zone - Heating
▪ Additional zone - Cooling
▪ Tank (only available to installers)
INFORMATION
To operate weather-dependent, correctly configure the setpoint of the main zone,
additional zone or tank. See
"10.5.4 Using weather-dependent curves" [ 4 161].
10.5.2 2-points curve
Define the weather-dependent curve with these two setpoints:
▪ Setpoint (X1, Y2)
▪ Setpoint (X2, Y1)
