3.2 Switch Box

The switch box is located in the heat pump. It can be accessed
by removing the lower front cover.
The switch box contains the supply connection terminals, as
well the power contactors, the soft starter unit and the heat
pump manager.
The heat pump manager is a convenient electronic regulation
and control device. It controls and monitors the entire heating
system on the basis of the external temperature, including hot
water preparation and safety systems.
The customer must install the external temperature sensor,
which is included in the scope of supply of the heat pump man-
ager together with the necessary fixing accessories.
The enclosed operating instructions describe the function and
use of the heat pump manager.

Accessories

4.1 Remote control

A remote control adds convenience and is available as a special
accessory. Operation and menu navigation are identical to
those of the heat pump manager. Connection takes place via an
interface (special accessories) with RJ 12 Western plug.
NOTE
In the case of heating controllers with a removable operating
element, this can also be used directly as a remote control.
4.2 Building management
technology
The heat pump manager can be connected to a building man-
agement system network via supplementation of the relevant
interface plug-in card. The supplementary installation instruc-
tions of the interface card must be consulted regarding the
exact connection and parameterisation of the interface.
The following network connections can be made on the heat
pump manager:
 Modbus
EIB, KNX

Ethernet

EN-4

4.3 Thermal energy meter WMZ

4.3.1 General description
The thermal energy meter (WMZ 25/32) is used for measuring
the quantity of thermal energy supplied. It is available as an ac-
cessory. Due to the additional heat exchanger, two thermal en-
ergy meters are required for measuring the quantity of thermal
energy.
Sensors in the flow and return of the heat exchanger pipes and
an electronics module acquire the measured values and trans-
mit a signal to the heat pump manager, which, depending on
the current operating mode of the heat pump (heating/DHW/
swimming pool), totals the thermal energy in kWh and displays
them in the operating data and history menu.
NOTE
The thermal energy meter complies with the quality
requirements of the German market incentive programme
subsidising efficient heat pumps. The thermal energy meter is
not subject to obligatory calibration, and can thus not be used
for the heating cost billing procedure!
4.3.2 Hydraulic and electrical integration of
the thermal energy meter
The thermal energy meter requires two measuring devices for
data acquisition.
A measuring tube for the flow measurement

This must be installed in the heat pump flow (observe flow
direction).
 A temperature sensor (copper pipe with immersion sleeve)
This must be installed in the heat pump return.
The installation locations for both measuring tubes should be
as close to the heat pump as possible in the generator circuit.
The distance from pumps, valves and other installations must
be taken into account, as eddying effects could lead to incor-
rect thermal energy metering (a calming section of 50 cm is
recommended).
