Danger
Incorrect wire allocation can
cause severe injury and damage
the appliance.
Never interchange wires "L" and
"N".
■ In negotiations with your power supply
utility, different supply tariffs for the
main power circuits may be offered.
Observe the technical connection
requirements of the power supply util-
ity.
■ If the compressor and/or instantane-
ous heating water heater (if installed)
are operated at an economy tariff
(power-OFF), provide an additional
cable (e.g. 3 x 1.5 mm
2
) for the power-
OFF signal from the distribution board
(meter box) to the heat pump control
unit.
■ The allocation of the power-OFF (for
compressor and/or instantaneous
heating water heater) is made via the
type of connection and by setting
parameters in the heat pump control
unit.
In Germany, the power supply can be
cut off for up to 3 x 2 hours per day
(24 h).
■ The
heat pump control unit/PCB
must be supplied
without
blocking by
the power supply utility; tariffs that are
subject to possible shutdown must not
be used here.
The power supply to the heat pump
control unit (3 x 1.5 mm
2
) and the cable
for the power-OFF signal can be com-
bined in a 5-core cable.
■ Protect the power supply to the heat
pump control unit with 16 A max.
■ For accessories and external compo-
nents that are not to be connected to
the heat pump control unit, make the
power connection with the same
phase as the heat pump control unit;
we recommend using the same fuse/
MCB.
Connection to the same fuse/MCB
provides additional safety when the
power is switched off. Observe the
power consumption of the consumers
connected.
Information regarding the compres-
sor power supply
■
!
Please note
An incorrect phase sequence
can cause damage to the appli-
ance.
Make the compressor power
supply
only
in the phase
sequence specified (see termi-
nal) with a
clockwise
rotating
field.
■ Characteristics of the compressor
power fuses: see "Specification".
