Accessories

4.1 Connecting Flanges

The use of flat-sealing connecting flanges allows the unit, as an
option, to be connected by means of flanges.

4.2 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 inter-
face (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.
4.3 Building management
technology
The heat pump manager can be connected to a building man-
agement system network via supplementation of the relevant in-
terface plug-in card. The supplementary installation instructions
of the interface card must be consulted regarding the exact con-
nection and parameterisation of the interface.
The following network connections can be made on the heat
pump manager:
 Modbus
 EIB, KNX
 Ethernet

4.4 Room climate control station

With cooling using panel heating/cooling systems, regulation is
carried out according to the room temperature and humidity
measured by the room climate control station.
This is done by setting the desired room temperature on the heat
pump manager. The minimum possible cooling water tempera-
ture is calculated from the room temperature and humidity meas-
ured in the reference room. The control response of the cooling
system is influenced by the currently measured room tempera-
ture and the set room set temperature.

4.5 Thermal energy meter WMZ

4.5.1 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 transmit
a signal to the heat pump manager, which, depending on the cur-
rent 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!
4.5.2 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 incorrect
thermal energy metering (a calming section of 50 cm is recom-
mended).
