7.1 General Information
The following connections need to be estab-lished on the heat
pump:
Flow and return of the brine (heat source system)
supply/return flow of the heating system
Temperature sensor
Voltage supply
7.2 Connection on Heating Side
ATTENTION!
The heating system must be flushed prior to connecting the heat pump.
Before completing the heat pump connections on the heating
water side, the heating installation must be flushed in order to re-
move any impurities that may be present, as well as residues of
sealing material, and the like. Any accumulation of deposits in
the condenser may result in a total failure of the heat pump.
Once the installation on the heating side has been completed,
the heating system 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. 5 µm).
Scale formation in domestic hot water heating systems cannot be
avoided, but in systems with flow temperatures below 60 °C, the
problem can be disregarded. With high-temperature heat pumps
and in particular with bivalent systems in the higher performance
range (heat pump + boiler combination), flow temperatures of
60 °C and more can be achieved. The following standard values
should therefore be adhered to with regard to the filling and
make-up water according to VDI 2035, sheet 1: The total hard-
ness values can be found in the table.
Fig. 7.1:Guideline values for filling and make-up water in accordance with
VDI 2035
For systems with an above-average specific system volume of
50 l/kW, VDI 2035 recommends using fully demineralized water
and a pH stabiliser to minimize the risk of corrosion in the heat
pump and the heating system.
ATTENTION!
With fully demineralized water, it is important to ensure that the minimum
permissible pH value of 7.5 (minimum permissible value for copper) is
complied with. Failure to comply with this value can result in the heat
pump being destroyed.
Heating water minimum flow rate
The minimum heating water flow rate through the heat pump
must be assured in all operating states of the heating sys-
tem. This can be accomplished, for example, by installing a dual
differential pressureless manifold.
Provided the heat pump manager and heating circulating pumps
are ready for operation, the frost protection feature of the heat
pump manager is active. If the heat pump is taken out of service
or in the event of a power failure, the system has to be drained.
In heat pump installations where a power failure cannot be read-
ily detected (holiday house), the heating circuit must contain a
suitable antifreeze product.
7.3 Connection on Heat Source
Side
The following procedure must be observed when making the
connection:
Connect the brine line to the flow and return pipe heat source of
the heat pump.
The hydraulic integration diagram must be adhered to.
ATTENTION!
The supplied strainer must be fitted in the heat source inlet of the heat
pump in order to protect the evaporator against the ingress of impurities.
In addition, a microbubble deaerator must be installed in the heat
source system.
The brine liquid must be produced prior to charging the system.
The brine concentration must be at least 25 %. Freeze protection
down to -14 °C can thus be ensured.
Only antifreeze products on the basis of mono-ethylene glycol or
propylene glycol may be used.
The heat source system must be vented (de-aerated) and
checked for leaks.
ATTENTION!
The brine solution must contain at least 25 % of an antifreeze agent on a
mono-ethylene glycol or propylene glycol basis and must be mixed prior
to filling.
NOTE
A suitable de-aerator (micro bubble air separator) must be installed in the
heat source circuit by the customer.
7.4 Temperature sensor
The following temperature sensors are already installed or must
be installed additionally:
External temperature sensor (R1) supplied (NTC-2)
Return temperature secondary circuit (R2) installed (NTC-
10)
Flow temperature secondary circuit (R9) installed (NTC-10)
Flow temperature primary circuit (R6) installed (NTC-10)
