n
Connect the two-wire control cable to terminals
F1, F2 and the earth terminal.
n
When connecting the control cable, make sure
that polarity is correct.
n
If the outdoor module is installed on a roof, it
and the supporting structure must be earthed
separately. (Connection to a lightning rod or a
concrete-footing earth electrode)
n
In the seriesWKF/WKF-compact 180 it must be
ensured that only the terminals L1(R), L2(S),
L3(T) and N are connected (see Fig. 51).

NOTICE!
Make sure to connect the outdoor unit neutral
connector properly, otherwise the varistors on
the line-filter circuit board will be destroyed.
Temperature sensors
n
The number of sensors required can vary with
the type of system.
n
Observe the pertinent notes for the sensor
position found in the hydraulic schematic.
n
The standard model includes an external
sensor (S10), a submersible sensor (intended
for use as a custom hot-water sensor (S08)
and a sensor for a total inlet at the indoor
module.
n
When connecting solar panels, the PT-1000
sensor (S01) as a collector sensor and a
PT-1000 sensor (S02) as a lower storage tank
sensor must be used.
n
All sensors are to be connected to the indoor-
module switching-cabinet according to the ter-
minal-assignment diagram.
Contact sensor
Contact sensors can be mounted on the pipes, to
measure the heating-circuit temperatures, for
example.
n
The contact sensor is fastened to a pipe with
the trapezoidal brackets and retaining strap
provided.
n
Clean the mounting point on the pipe. Subse-
quently a thermal compound (A) is applied and
the sensor is fixed in position.
