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

▪

: Domestic hot water tank

Go through the temperatures.

Change the temperature.

Go to the next temperature.

Confirm changes and proceed.

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.
