Power supply
Make the power connection in
accordance with the relevant power
connection diagram. the supply
voltage at terminal l and the phase
l´ - switched by the power supply
company - must be routed via the
same rCD. the wPF must be able to
be separated from the power supply
by an additional isolator, which
disconnects all poles with at least
3 mm contact separation. For this, use
contactors, main isolators, fuses, etc.
isolate all poles of the heating system
supply prior to carrying out any
installation work. the cable entries
in the wall mounting enclosure are
suitable for rigid and flexible cables
with an outside diameter between
6 mm and 12 mm. secure all cables
to the wall immediately below the
wall mounting enclosure using correct
strain relief fittings. the red wedges
supplied are designed to secure the
cables/leads inside the enclosure.
BUS connection
the bUs cable enables the
communication with the appliance
and enables the allocation of
appliance-specific addresses for
controlling the heat pump. only
connect the bUs cable during
commissioning.
bUs cable: J-Y (st) 2 x 2 x 0.8 mm
Outside temperature sensor AFS 2
(accessory)
install the outside temperature sensor
on a north or north-eastern wall
behind a heated room 2.5 m above
ground level and 1 m away from
windows and doors. the outside
sensor should be freely exposed to the
elements, but never to direct sunlight.
Contact sensor AVF 6
thoroughly clean the pipe before the
installation. Apply heat conducting
paste and secure the sensor with a tie.
