REMKO WKF Series User Manual

2.7 Electrical connection
general notes
n It is necessary to lay a mains cable both to the
outdoor unit and, separately
, to the indoor unit.
n Power to the indoor units may not be discon-
nected by the power company when fitted with
an off-period circuit (anti-freeze protection).
n All 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.
n The electrical connection between outdoor and
indoor units is made using a sheathed two-wire
control line.
n Where applicable, another three-phase
400V/3~/50 Hz power supply shall be provided
to the indoor module for auxiliary heater.
n The 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).
n A connection schematic along with corre-
sponding circuit diagrams can be found in the
“Electrical layout” and “Circuit plans” chapters
of this manual.
n Special rates for the operation of heat pumps
may be offered by the power utility.
n Ask your local power utility about the details of
any rates that might be available.
