■ Time program
In accordance with the times programmed in the
"Heating" program, the control unit time switch regu-
lates between central heating with standard room
temperature and central heating with reduced room
temperature.
Every operating mode has its own set level.
■ Outside temperature
A heating curve must be set to adjust the control unit
to the building and the heating system. See chapter
"Setting the heating curves"
The heating curve characteristics determine the set
flow temperature subject to the outside temperature
and regulate based on the average outside tempera-
ture. This is made up of the actual and the adjusted
outside temperature.
Room temperature
■
In conjunction with the remote control and room tem-
perature hook-up (coding address "B0"):
Compared to the outside temperature, the room tem-
perature has a greater influence on the set flow tem-
perature (change via coding address "B2").
