REMKO WKF-120-180Duo Electrical wiring - Manual (Page 12)

2.4 General notes
n It is necessary to lay a power supply cable both
to the outdoor unit and, separately, to the
indoor unit.
n Power to the indoor unit may not be discon-
nected by the power company if there is a dis-
able period circuit (anti-freeze protection).
n The indoor unit requires a single-phase power
supply of 230 V / 50 Hz.
The outdoor units if the WKF 180 Duo require
a three-phase power supply of 400 V / 50 Hz.
The WKF 120 Duo outdoor units required a
230 V / 50 Hz power supply
n The electrical connection between outdoor and
indoor units is made using a shielded three-
core control line.
n Where applicable, a separate power supply
shall be provided to the indoor unit for an auxil-
iary heater.
n The heat pump manager needs to know
whether a power-company enable or disable
period is in effect. A potential-free switch must
be provided by the customer for this purpose.
(A closed switch signifies an enable, an open
switch a disable period.)
n A connection schematic along with corre-
sponding circuit diagrams can be found in the
"Connection diagram" chapter of this manual.
n Special rates for heat pumps may be offered
by the power company.
n Ask your local power company about the
details of any rates that might be available.
