5.3 Electrical Connection

The hot-water heat pump is wired ready for use; power is sup-
plied via connection cables plugged into an earthed wall socket
(~230 V, 50 Hz). This socket has to remain accessible after in-
stallation.
To control external devices for the second heat generator (hot-
water heat pumps with internal heat exchanger only), a separate
cable has to be connected to the device via an available cable
union and be strain relieved. (For this electrical connection, the
hot-water heat pump plastic cover has to be removed.) The cable
must then be led through the available cable feedthrough pro-
vided, and guided through the partition. The electrical connection
terminal (X5 – 4/5/PE) with a floating contact to control (ON/OFF)
the external ancillary devices (pump, solenoid valve etc.) is lo-
cated on the rear of the partition in the device.
External heating element control
It is possible to optionally control the heating element via an ex-
ternal switch (e.g. timer), in parallel to the "Heating Element"
switch on the hot-water heat pump operator panel. For this con-
nection, a floating contact on the external switchgear is required.
Furthermore, an additional cable (min. 2 x 1.0 mm
outside diameter 10 mm) must be inserted into the device and at-
tached to connection 6 and 7 of terminal strip X5.

Heat pump operation is blocked if the factory-mounted copper
bridge between pole terminals 8 and 9 is removed (see Section
6.2).

Start-Up

6.1 Hot-Water System

ATTENTION!
Only operate hot-water heat pump when filled with water!
Hot-water system requirements
The following materials may be found in the consumer's hot-
water system:
Copper
Stainless steel
Brass
Plastic
Depending on the materials used in the hot-water system (cus-
tomer installation), material incompatibility may lead to corrosion
damage. This especially applies to zinc-plated and aluminous
materials. If there is a risk of water contamination during opera-
tion, the installation of a filter may be required.

Hot-water system start-up
All installations at the water circuit, air circuit, as well as all
electrical installations must have been performed correctly
and fully completed
Filling hot-water system via external connection.
De-aerate hot water system (open hot-water taps at the
highest extraction points until there are no more traces of
air).
Check entire hot-water system for leaks.
Supply voltage.
Switch on "Heat Pump" switch (see illustration).
The desired hot-water temperature is infinitely adjustable
(up to 60 °C) via the temperature control button (see illustra-
tion). A certain heat-up time should always be allowed for,
until the desired temperature level has been reached.
