temperature - dependent switching between summer and
winter modes is active for the heating circuit concerned .
2) When the outside temperature is adjusted, changes to the
measured outside temperature are delayed and

5.2.4 DHW alternating operat i on settings
In DHW alternating operation, DHW and heating have equal
priority and alternate based on time. A heat requirement from
the heating system is not taken into account while DHW heating
is active . and vice versa.
If DHW alternating operation is not active, DHW heating has
priority and interrupts the heat requirement of the heating
system, if necessary .
Menu: DHW alternating operation

In the event of a simultaneous heat energy
demand, the system will alternate between

5.2.5 Sett i ng for heat i ng circuit 1 priority
This menu item allows the other heating circuits to be restricted
via heating circuit 1.
When Priority heating ci rcu it 1 is activated , heating circuit 1
is the primary heating circuit. Heat requirements for other
circuits are only handled if heating circuit 1 has a heat
requirement. This means that the flow temperature required
for heating circuit 1 limits the flow temperature of the other
heating circuits.
An example :
Heating circuit 1 requires 50 ·C.
Heating circuit 2 requires 55 ·C, but receives a maximum of
500C (in line with heating circuit 1) .
Heating circuit 3 requires 45 ·C and receives 45 OC (not
limited by heating circuit 1) .
5.3 Changing the setti ng s for DHW heating

These settings are only available if a DHW system is installed in
the system . The water can be heated via a cylinder .

WARNIN G: Risk of scalding!
If the temperature for extra DHW has been set
to in excess of 60 OC or thermal disinfection
has been activated to avoid legionella , the
DHW is heated once to in excess of 60·C or
65 ·C. The factory setting for DHW
temperature depends on the installed heat
pump . There is a risk of scalding at the draw ·
off points if the temperature is set higher than
this.
~ Make sure that a thermal mixer is installed .
If
in doubt. ask your installer .
There is a factory · set custom time program for DHW heating .
Alternatively , DHWheatingcan be constant (~Chapter 5.3 .2,
page 21' .
5.3.1 Se tt ing the operat lnc mode for DHW heatin g
In the default settings, DHW is heated based on a separate time
program .
If Own time program is set, the DHW operating mode is
active daily from 05 : 00 (from 07 : 00 on Saturdays and
Sundays) until 23:00 (time program default settings) .
