Assembly
IMPORTANT
The load-bearing capacity of the wall must be guar-
anteed.
1. Align drill pattern, mark drill holes and drill.
“Drill pattern“, page 12
2.

3. Set aside the front hood so that it is protected
from damage.
4.
Use the plugs and screws supplied to fix the
wall-mounted controller onto the wall:
The plugs supplied are only suitable for use with the
following types of walls:
●
Concrete
●
Solid lightweight concrete blocks
●
Cavity block made of lightweight concrete
●
Cellular concrete
● Prestressed concrete - hollow ceiling/floor slabs
●
Natural stone with dense, close-grained micro-
structure
●
Solid calcium silicate blocks
●
Perforated calcium silicate blocks
●
Solid bricks
●
Vertically perforated (honeycomb) bricks
● Hollow floors/ceilings made of clay bricks, con
-
crete or similar
●
Solid gypsum boards
● Gypsum boards and gypsum fibre boards
●
Particle boards
The board material must be dimensioned with
sufficient thickness to ensure secure fixing.
Appropriate fixing material must be provided on site
for other types of wall constructions.
IMPORTANT
The gap between the unit and the wall helps back
ventilation. It may not be sealed or closed off.
5. Lay cable glands at a distance of at least 2 cm
from the wall-mounted controller.
6 Install the hydraulic connections
IMPORTANT
Dirt and deposits in the (existing) hydraulic system
can cause damage to the heat pump.
►
Ensure that a sludge separator is installed in the
hydraulic system.
►
Rinse the hydraulic system thoroughly prior to es-
tablishing the hydraulic connection of the heat
pump.
Cross-sections and lengths of the pipes for the
heating circuit are adequately dimensioned.
The free pressing of the recirculating pump
produces at least the minimum throughput
required for the unit type (
“Technical data /
Scope of supply”, page 11).
6.1 Supply and return sensor
1.
Fasten the supply volumetric flow meter
(②)
to the
heat-conducting pipe of the supply line coming
from the heat pump
(①)
using cable ties and ther-
mal compound.
2. Fasten the return sensor
(④)
to the heat-conduct-
ing pipe of the return line leading to the heat pump
(③)
using cable ties and thermal compound.
