5.2 Adjust settings for automatic operation of
house heating
Cooling is disabled in the UK model to
comply with the regulations for RHI.
Menu: Heating/Cooling
Optimised operation normally produces the highest comfort
with the largest possible energy savings. A constant
temperature can be set in cooling mode.
Optimised operation for each heating circuit is active with the
default settings
Heating circuit 1 – 4
If several heating circuits are installed and configured, the
settings for heating circuits 1 – 4 are changed in the same way
as in systems with one heating circuit. The changes only apply
however to the selected heating circuit. If the heating circuits
are given names that are easy to distinguish, this considerably
simplifies the selection of the correct heating circuit.
5.2.1 Adjust Time program for automatic operation of
house heating
The time program for house heating is only active if automatic
mode is active ( chapter 4.2, page 9).
This is how you can set the same break points for several
weekdays:
▶ Set break points for a group of several days, e.g.
Mon-Sun or Mon-Fri.
▶ Adjust the time program for the individually deviating
weekdays during Monday – Sunday (detailed description
 table 12, page 16).
Menu: Time program
The time programs automatically switch from one mode to
another at fixed times. The control unit has two time programs
for each heating circuit. You can program two break points per
day, with their own operating mode. The default settings for the
time programs result in reduced heating during the night.
Operation without a time program results in the highest
possible energy saving.
If the settings, temperatures or time program break points do
not match your requirements you can adjust the time program.
Talk to your installer if you do not want to heat the house during
the night. He can also set the temperature reduction mode.
The following table shows how to activate and select a time
program for house heating.

Rename heating
circuit
The name of the selected heating circuit
can be adjusted here (this function is only
available if more than one heating circuit
is installed). This simplifies the selection
of the correct heating circuit, e.g.“floor
heating” or“loft”. The names are preset
with Heating circuit 1 – 4 ( table 13,
page 18).
Rename time
program
It is possible to change the name of the
time programs in the same way as the
heat circuits. It simplifies the selection of
the correct time program to give the
programs names like“family”or“night
shift”.
