Installation

7.1 General Information

The following connections need to be established on the heat
pump:
 Flow and return flow of the well system
 Flow and return flow of the heating system
 Power supply


Temperature sensor

7.2 Heating System Connection

ATTENTION!
Flush the heating system prior to connecting the heat pump.
Before connecting the heating water system to the heat pump,
the heating system must be flushed to remove any impurities,
residue from sealants, etc. Any accumulation of deposits in the
liquifier could cause the heat pump to completely break down.
Once the heating system has been installed, it must be filled, de-
aerated and pressure-tested.
Consideration must be given to the following when filling the sys-
tem:
 Untreated filling water and make-up water must be of drink-
ing water quality (colourless, clear, free from sediments)
 Filling water and make-up water must be pre-filtered (pore
size max. 5µm).
Scale formation in hot water heating systems cannot be com-
pletely avoided, but in systems with flow temperatures below
60°C the problem can be disregarded. With medium and high-
temperature heat pumps, temperatures above 60°C can be
reached. The following standard values should therefore be ad-
hered to concerning the filling water and make-up water (accord-
ing to VDI 2035 Sheet 1):

Minimum heating water flow rate
The minimum heating water flow of the heat pump (see "Device
information", Chap. 11, section 4.1) must be ensured in all oper-
ating states of the heating system. This can be accomplished, for
example, by installing either a manifold without dual differential
pressure or an overflow valve.
NOTE
The use of an overflow valve is only recommended for panel heating and
a max. heating water flow of 1.3 m³/h.
System faults may result if this is not observed.

Antifreeze protection for installation locations
prone to frost
The antifreeze function of the heat pump manager is active
whenever the heat pump manager and the heat circulating
pumps are ready for operation. If the heat pump is taken out of
service or in the event of a power failure, the system has to be
drained. The heating circuit should be operated with a suitable
antifreeze if heat pump systems are implemented in buildings
where a power failure can not be detected (holiday home).

7.3 Heat Source Connection

The following procedure must be observed when connecting the
heat source:
Connect the well pipes to the heat pump's flow and return.
ATTENTION!
The well water must comply with the required water quality standards.
The hydraulic plumbing diagram must be adhered to.
7.4 Temperature sensor
The following temperature sensors are already installed or must
be installed additionally:
 External temperature sensor (R1) supplied
 Return temperature secondary circuit (R2) installed
 Flow temperature secondary circuit (R9) installed
Flow temperature primary circuit (R6) installed
