▪ Additional zone - Heating
▪ Additional zone - Cooling

INFORMATION
To operate weather dependent, correctly configure the
setpoint of the main zone, additional zone or tank. See
"5.9.4 Using weather-dependent curves"
17].
5.9.2
2-points curve
Define the weather-dependent curve with these two setpoints:
▪ Setpoint (X1, Y2)
▪ Setpoint (X2, Y1)
Example
Y1

Description
a
Selected weather dependent zone:
▪
: Main zone or additional zone heating
▪
: Main zone or additional zone cooling
▪
: Domestic hot water
X1, X2
Examples of outdoor ambient temperature
Y1, Y2
Examples of desired tank temperature or leaving water
temperature. The icon corresponds to the heat emitter
for that zone:
▪
: Underfloor heating
▪
: Fan coil unit
▪
: Radiator
▪
: Storage tank
Possible actions on this screen
Go through the temperatures.
Change the temperature.
Go to the next temperature.
Confirm changes and proceed.
5.9.3
Slope-offset curve
Slope and offset
Define the weather-dependent curve by its slope and offset:
▪ Change the
slope
to differently increase or decrease the
temperature of the leaving water for different ambient
temperatures. For example, if leaving water temperature is in
general fine but at low ambient temperatures too cold, raise the
slope so that leaving water temperature is heated increasingly
more at decreasingly lower ambient temperatures.
▪ Change the
offset
to equally increase or decrease the
temperature of the leaving water for different ambient
temperatures. For example, if leaving water temperature is always
a bit too cold at different ambient temperatures, shift the offset up
to equally increase the leaving water temperature for all ambient
temperatures.

WD curve after changes (as example):
▪ When slope is changed, the new preferred

preferred temperature at X2.
▪ When offset is changed, the new preferred
temperature at X1 is equally higher as the preferred
temperature at X2.
