4 Accessories
4.1 Brine Circuit Manifold
The brine circuit manifold merges the individual collector loops
of the heat source system into a single main pipe which is con-
nected to the heat pump. Integrated ball valves allow the indi-
vidual brine circuits to be shut off for de-aeration purposes.
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
interface (special accessories) with RJ 12 Western plug.
NOTE
º
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
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
ATTENTION!

!
If the heat pump or circulating pump is controlled externally,
an flow rate switch is required to prevent the compressor
from being switched on when there is no volume flow.
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 tem-
perature is calculated from the room temperature and humidity
measured in the reference room. The control response of the
cooling system is influenced by the currently measured room
temperature 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 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
º
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.
To avoid eddying effects which could lead to incorrect meas-
urements, there should be a gap of 50 cm between the meas-
uring devices and other installed components such as pumps
or valves.
