Minimum heating water flow
The minimum heating water flow through the heat pump (see
"Device information", Chap. 11, section 4.1) must be ensured in
all operating states of the heating system. This can be accom-
plished, for example, by installing a manifold without differential
pressure.
Antifreeze
A method of manual drainage (see illustration) should be pro-
vided for heat pumps which are exposed to frost. The antifreeze
function of the heat pump manager is active whenever the man-
ager and the heat circulating pump are ready for operation. The
system has to be drained if the heat pump is taken out of service
or in the event of a power failure. The heating circuit should be
operated with a suitable antifreeze if heat pump systems are im-
plemented in buildings where a power failure cannot be detected
(holiday home).

6.3 Electrical connection

A standard four-core cable is used for connecting the heat pump
to the power supply.
The cable must be provided by the customer. The conductor
cross section is selected in accordance with the power consump-
tion of the heat pump (see appendix Device information) and the
applicable VDE (EN) and VNB regulations.
An all-pole disconnecting device with a contact gap of at least
3 mm (e.g. utility blocking contactor or power contactor) as well
as a 3-pole circuit breaker with common tripping for all external
conductors must be installed in the power supply (tripping current
in compliance with the device information). When connecting,
ensure that the incoming supply has a clockwise rotating field.
Phase sequence: L1, L2, L3.
ATTENTION!
Ensure that there is a clockwise rotating field: With incorrect wiring the
starting of the heat pump is prevented. A corresponding warning is
indicated on the display of the heat pump manager (adjust wiring).
The control voltage is supplied via the heat pump manager.
The heat pump manager has a 230 V AC-50 Hz power supply
and is connected in compliance with its own operating instruc-
tions.
Three separate lines are used as control lines. (These are not in-
cluded in the scope of supply of the heat pump). Two of these ca-
bles are equipped with rectangular plug connectors which must
be connected to the heat pump manager and to the underside of
the switch box. One of these two cables is for the 230 V voltage
level, the other for the extra-low voltage level. The third cable
serves as a communication connection between the heat pump
manager and the electronic expansion valve (N23), and must be
connected to the "field card" on the heat pump manager and to
the expansion valve driver (N23/Network) in the switch box of the
heat pump.
The control lines (not included in the scope of supply) have rec-
tangular plug connectors on both ends. One end is connected to
the heat pump manager, and the other end is connected to the
switch box in the heat pump. The plug connections to the heat
pump are located on the bottom of the switch box.
Two separate lines are used as control lines. One of the lines is
designed for the 230 V control voltage level, the other for the sig-
nal and/or extra-low voltage level.
More detailed information can be found in the operating instruc-
tions of the heat pump manager.
For detailed information, see circuit diagrams in the appendix.
