5 Operating modes

Six different operating modes can be selected using the (MODE)
button. A time delay occurs while switching the operating mode.
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
Summer
Auto
Vacation
(lower operation)
Party
(daytime operation)
2nd heat generator
(HG2)
The system operates in cooling operation and 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.
Domestic 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 domestic hot water heating are activated automatically. Domestic
water 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.
The vacation operating mode lowers the heating characteristic curve and activates the hot water
block. Both functions are independent of any time controls, 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.
The 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, the 2nd heat generator is the oil or gas heating. Time programs and heating curve
settings remain active.

systems is carried out using electric heating elements. In the case of
bivalent systems, the 2nd heat generator is used.
