INFORMATION
To operate weather-dependent, correctly configure the
setpoint of the main zone, additional zone or tank. See
"5.9.4 Using weather-dependent
5.9.2

2-points curve

Define the weather-dependent curve with these two setpoints:
▪ Setpoint (X1, Y2)
▪ Setpoint (X2, Y1)
Example
Y2
Y1
X1
X2
Item
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
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
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.
