NOTICE
When laying the cable inside the building,
ensure that unshielded power supply cables
(outdoor unit voltage supply) and shielded
cables (LIN-Bus) are laid separately from
each other.
If the wall penetration is used, the necessary
distance from adjacent pipes and cables is
ensured.
NOTICE
The control element of the heat and heat pump
regulator can be connected with a computer or
network using a network cable designed for such
purposes, therefore allowing the heating and heat
pump regulator to be controlled remotely.
If such a connection is required, install a shielded
network cable (category 6, with RJ-45 connector)
during the electrical connection work and con-
nect it parallel to the existing control cable of the
heating and heat pump regulator.
Connect BUS cable
Strip the BUS cable insulation and push the shield
back over the insulation.
Insert the end of the insulated cable with the
shield into the shield terminal.
Feed the end with the individual cores through
one of the two grommets.
Core assignment:
1 12 V
2 GND
3 LIN
Use cable ties and heat transfer compound to fix the
return flow sensor (2) to the return flow (heat carrying
pipe) to the heat pump (4).
Hydraulic connections documents
The electrical connection between the heat pump and
hydraulic module is made using the 3 pre-installed
cables on the heat pump.
On site, the hydraulic module is connected from the
subdistribution board using the following cables
“Terminal diagram” for respective model.

1 Heat pump
2 Compressor (5 cores)
3 Control (3 cores)
4 LIN-Bus (3 cores, shielded)
5 Hydraulic module
6 Heating element load
cable (5 cores)
7 Control voltage (3 cores)
8 Compressor (5 cores)
9 Subdistribution board
If laid on site:
●
Seal reserve conduits on unit side.
Feed the three connection cables through the three
ducts of the wall penetration - use lubricant!
