5 Operating Modes
6 different operating modes can be selected using the button
(Mode). There is a time delay between switching modes. The
operating mode can be changed each time the button is pressed
in the order shown below.
COOLING
Selectable only when the
cooling controller is
connected
(see Installation and
Start-up)
SUMMER
AUTO
VACATION
(lower operation)
PARTY
(daytime operation)
2nd heat generator
(HG2)
No action
The system operates in cooling operation. Individual control functions are activated. This
operating mode can only be activated if a cooling controller is connected to the heat pump
manager and the cooling function has been enabled in the preconfiguration.
Only domestic hot water and swimming pool water are heated in the SUMMER operating mode.
Space heating is not activated. (Frost protection is ensured.)
The heat pump operates in automatic operation. Programmed lowering times, raising times and
shut-off-times for heating and DHW heating are activated automatically. DHW heating, heating
and swimming pool heating are activated according to priority. The heat pump and the 2nd heat
generator are switched on or off as required.
A lowering of the heating characteristic curves and a hot water block are activated in the
VACATION operating mode. Both functions are independent of any relevant timings, but the
lower values set for these functions still apply. The duration of the VACATION operating mode
can be set in the menu "1 Settings – Mode – Vacation mode". After this time period has
elapsed, the system automatically switches back to automatic operation again.
A programmed lowering of the heating characteristic curves is overridden in the PARTY operating
mode. The duration of the PARTY operating mode can be set in the menu "1 Settings – Mode –
Party mode". After this time period has elapsed, the system automatically switches back to
automatic operation again.
The heat pump is switched off in this operating mode and the entire heat supply is provided by
the 2nd heat generator (HG2). This is the immersion heater in mono energy systems. In bivalent
systems it is the oil or gas heating. Time programs and heating curve settings remain active.

Heating operation and DHW preparation in mono energy systems is
carried out using electric heating elements. In the case of bivalent
systems, the 2nd heat generator is used.
