REMKO WKF 85 - Manual (Page 57)

n Electrical protection for the system is imple-
mented in accordance with the information in
the technical data. Observe the required con-
ductor cross-sections!
n All cables must be connected with the correct
polarity and strain relief.
n Follow the connection schematic and the circuit
diagram.
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. 61).

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.
