3.2 Switch box
The switch box located in the device can be folded out once the
bottom front cover has been removed and the fixing screw has
been loosened.
The power supply terminals, power contactors, the soft starter
units and the extended controller unit (refrigeration circuit con-
trol) are inside the switch box. The refrigeration circuit control
monitors and controls all heat pump signals and communicates
with the heat pump manager.
Communication and control or mains cables, which should be
routed apart from each other, are fed into the switch box
through the cable entry area on the side plate.

3.3 Heat pump manager
The heat pump manager included in the scope of supply must
be used to operate the air-to-water heat pump.
The heat pump manager is a convenient electronic regulation
and control device. It controls and monitors the entire heating
system based on the outside temperature, as well as domestic
hot water preparation and safety systems.
Sensors for heating demand and outside temperature to be in-
stalled on site, including mounting material, are included with
the heat pump manager.
The functions and usage of the heat pump manager are de-
scribed in the operating instructions supplied with it.
