3.2 Switch Box
The switch box is located in the heat pump. After removing the
bottom front cover, the switch box is accessible. Where neces-
sary (repairs on the refrigeration circuit), the switch box can be
unscrewed from the basic device (remove 4x M4 screws) and put
down at the side in front of the device (see Cap. 7.5.2 on pag. 10)
The switch box contains the supply connection terminals, as well
the power contactors, the soft starter unit and the heat pump
manager.
The heat pump manager is a convenient electronic regulation
and control device. It controls and monitors the entire heating
system on the basis of the external temperature, including hot
water preparation and safety systems.
The customer must install the external temperature sensor,
which is included in the scope of supply of the heat pump to-
gether with the necessary fixing accessories.
The enclosed operating instructions describe the function and
use of the heat pump manager.
