2.7 Electrical connection
general notes
nIt is necessary to lay a mains cable both to the
outdoor unit and, separately, to the indoor unit.
nPower to the indoor units may not be discon-
nected by the power company when fitted with
an off-period circuit (anti-freeze protection).
nAll indoor units require a single-phase
230V/1~/50 Hz power supply.
The outdoor units of the WKF/WKF compact
80 to 130 series require a single-phase power
supply of 230V/1~/50 Hz and the outdoor units
of the WKF/WKF compact 170 series require a
three-phase power supply of 400V/3~/50 Hz.
nThe electrical connection between outdoor and
indoor units is made using a sheathed two-wire
control line.
nWhere applicable, another three-phase
400V/3~/50 Hz power supply shall be provided
to the indoor module for auxiliary heater.
nThe Smart-Control needs to know from the
power-company whether the power supply is
enabled or a blocking period is in effect. A
potential-free switch must be provided by the
customer for this purpose and connected to
contact S16. (Contact closed signifies enabled,
while contact open signifies a blocking period).
nA connection schematic along with corre-
sponding circuit diagrams can be found in the
“Electrical layout” and “Circuit plans” chapters
of this manual.
nSpecial rates for the operation of heat pumps
may be offered by the power utility.
nAsk your local power utility about the details of
any rates that might be available.
DANGER!
All electrical installation work must be done by
an electrician.
WARNING!
Always note the currently applicable VDE
guidelines and the notes in TAB 2007. The size
and type of the fuse are to be taken from the
technical data.
WARNING!
All cable sizes are to be selected according to
VDE 0100. Special attention should be given to
cable lengths, cable type and the kind of instal-
lation. The information in the connection dia-
gram and in the system overview are to be
seen as an acceptable installation possibility
only in a standard case!
NOTICE!
Make sure to connect the outdoor unit neutral
connector properly, otherwise the varistors on
the line-filter circuit board will be destroyed.
NOTICE!
The electrical connection for the units must be
made at a separate feedpoint with a residual
current device in accordance with local regula-
tions and should be laid out by an electrician.
Check all plugged and clamped terminals to
verify that they are seated correctly and make
permanent contact. Tighten as required.
2.8 Electrical connection - indoor
unit
The following instructions describe the electrical
connection of the WKF/WKF compact and WKF
Duo series.
1. Remove the housing from the upper section
by pressing it upwards and pulling it forwards
out of the rear groove.
2. Guide the supply cable to the indoor units
through the cable openings, and also route
the control line between indoor and outdoor
units and the cables for external devices and
probes into the indoor unit. Note that the
cable openings in the WKF/WKF compact
series are located above rather than below.
3. Connect the power supply of the indoor units
to the terminals.
4. Connect all secondary consumers
(HGM,HGU, changeover valves etc.) to the
I/O module.

nElectrical protection for the system is imple-
mented in accordance with the information in
the Technical Data. Observe the required con-
ductor cross-sections!
nAll cables must be connected with the correct
polarity and strain relief.
nThe power supply must be connected to ter-
minal L (phase) / N (neutral conductor) and PE
(earth conductor).
nFollow the connection schematic and the circuit
diagrams.
nThe two-wire control line is to be connected to
terminals A/B and the earth terminal.
nWhen connecting the control line, make sure
that polarity is correct.
nIf the outdoor unit is installed on a roof, it and
the supporting structure must be earthed sepa-
rately (connection to lightning conductors or
foundation earth/ground feature).
nWith the WKF/WKF compact 170 series, make
sure that only terminals L1(R), L2(S), L3(T)
and N are connected (see Fig. 11).

Temperature probes
nThe number of probes required can vary with
the type of system.
nObserve the relevant notes for the probe posi-
tion found in the hydraulic circuit diagram.
nThe standard scope of delivery includes the
outdoor probes (S10), an immersion probe
(provided for use as a domestic hot water
probe - (S08) as well as a probe for the com-
plete inlet in the indoor unit.
nWhen connecting up a solar plant, use a
PT-1000 probe (S01) as a collector probe and
a PT-1000 probe (S02) as the lower storage
tank probe.
nAll probes are to be connected to the indoor
units switch cabinet in accordance with the ter-
minal assignment diagram.
Contact probe
Contact probes can be mounted on the pipes, to
measure the heating-circuit temperatures, for
example.
nThe contact probes are fastened to a pipe with
the trapezoidal brackets and retaining strap
provided.
nClean the appropriate point. Subsequently a
thermal compound (A) is applied and the probe
is fixed in position.

External probe
The connection of an outdoor sensor is always
required for Smart Control.
nMount the external probe pointing skyward, in
a north-easterly direction, about 2.5 metres
above the ground. It may not be subjected to
direct sunlight and is to be protected against
excessive wind. Installation above windows or
air ducts is to be avoided.
nIn order to carry out the installation, remove the
