9.2 Preparations

For installation, remove the device from the wall mounting
enclosure:
f Release the snap-in tab found in the opening on the un-
f
derside of the wall mounting enclosure. Press the snap-in
tab with a screwdriver.
f Route a four-core CAN bus cable from the heat pump f
manager to the mounting position of the device.
The CAN bus cable must protrude 20 to 30 cm from the wall
for installation.
9.2.1 Installation with a flush box
For securing to a wall, we recommend using a flush box which
can hold this part of the CAN bus cable.
f Make sure that the screws supporting the flush box are
f
arranged either vertically or horizontally opposite one
another.
9.2.2 Installation without a flush box
f To secure the wall mounting enclosure, drill four holes f
(Ø 5 mm).
f When routing the CAN bus cable, be careful not to dam-
f
age it when drilling the fixing holes.
In the area around the power cable entry (behind the wall
mounting enclosure), a reservoir needs to be made to hold 20
to 30 cm of data cable.
f Break out one of the knock-outs in the wall mounting f
enclosure.
f Route the CAN bus cable through the hole from the back. f
