Description

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

Possible actions on this screen

Select slope or offset.

Increase or decrease the slope/offset.

When slope is selected: set slope and go to offset.

When offset is selected: set offset.

Confirm changes and return to the submenu.

Using weather-dependent curves

Configure weather-dependent curves as following:

To define the setpoint mode

To use the weather-dependent curve, you need to define the correct
setpoint mode:

Go to setpoint mode …

Set the setpoint mode to …

Main zone – Heating

To change the type for all zones (main + additional) and for the tank,
go to [2.E]

INFORMATION

Maximum and minimum setpoints

You cannot configure the curve with temperatures that are
higher  or  lower  than  the  set  maximum  and  minimum
setpoints for that zone or for the tank. When the maximum
or minimum setpoint is reached, the curve flattens out.

To fine-tune the weather-dependent curve: slope-offset curve

The  following  table  describes  how  to  fine-tune  the  weather-
dependent curve of a zone or tank:

Energy saving tips

Tips about room temperature

▪ Make  sure  the  desired  room  temperature  is  NEVER  too  high  (in

heating  mode)  or  too  low  (in  cooling  mode),  but  ALWAYS
according  to  your  actual  needs.  Each  saved  degree  can  save  up
to 6% of heating/cooling costs.

▪ Do  NOT  increase/decrease  the  desired  room  temperature  to

speed up space heating/cooling. The space will NOT heat up/cool
down faster.

▪ When  your  system  layout  contains  slow  heat  emitters  (example:

underfloor  heating),  avoid  large  fluctuation  of  the  desired  room
temperature  and  do  NOT  let  the  room  temperature  drop  too  low/
rise  too  high.  It  will  take  more  time  and  energy  to  heat  up/cool
down the room again.
