5.3.4 Setting summer/winter switchover threshold
This menu item is only available with weather-compensated
control. In order to be able to use weather-compensated
control, an outside temperature sensor must be installed.
The heating system is switched off in summer mode, the
heating system in switched on in winter mode. DHW heating is
independent of the switching between summer and winter
modes.

Changing the settings for DHW heating
Menu:
DHW
These settings are only available if at least one DHW system is
installed in the system. The water can be heated via a cylinder
or according to the instantaneous water heating principle.

1) Depending on the installed system, it may be necessary to
select a heating circuit (heating circuit 1-4).
•
If the cut-in optimisation is switched on,
the heating periods in the time program
are brought forward so that the set room
temperature is reached at the beginning
of the heating period.
•
If the cut-in optimisation is switched off,
the heating system is switched on at the
required times. The set room
temperature is reached slightly later.

programs
NOTICE:
System damage
▶ Do not switch over to summer mode if
there is a risk of frost.
Switching between summer and winter modes
is only active in automatic mode (by taking
account of the time program). For constant
heating circuits (e.g. for a swimming pool or a
ventilation unit) the the switching between
summer and winter modes is not available.

•
In summer, heating mode can be switched
off (
Permanently summer
).
•
The heating mode can be shut down based
on the outside temperature (
Summer
mode from
); this is only available if the
automatic mode is active in the heating
circuit.
•
The heating mode can be active constantly
(
Permanently winter
). However, the heat
source only goes into operation if it is too
cold inside.
If more than one heating circuit is installed, in-
stead of the above refer to the individual
heating circuit menu.

1) This menu item is only displayed if the outdoor-
temperature-dependent switching between summer and
winter modes is active for the heating circuit concerned.
If the adjusted outside temperature
2)
exceeds
the temperature threshold set here, the
heating system is switched off.
If the adjusted outside temperature falls below
the temperature threshold set here by 1 °C,
the heating system is switched on. In systems
with more than one heating circuit, this setting
always relates to the corresponding heating
circuit in each case.
2) When the outside temperature is adjusted, changes to the
measured outside temperature are delayed and
fluctuations reduced.

modes
WARNING:
Risk of scalding!
If thermal disinfection has been activated to
avoid legionella, the hot water is heated once
to in excess of 65 °C. The factory setting for
the hot water temperature is 60 °C. There is a
risk of scalding at the draw-off points if the
temperature is set higher than this.
▶ Make sure that a mixer is installed. If in
doubt, ask your Installer.
