7.1 General
The following connections need to be established on the heat
pump. The hydraulic integration diagram must be adhered to:
Flow and return of the well system
Flow and return of the heating system
Temperature sensor
Voltage supply
7.2 Connection on the heating side
CAUTION!
!
!
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 heat pump has been connected to the heating sys-
tem, it must be filled, de-aerated and pressure-tested.
CAUTION!
!!
The maximum test pressure in the heating circuit and the
primary circuit is 6.0 bar.
This value must not be exceeded.
The following points must be observed when filling the system:
Untreated filling water and make-up water must be of
drinking water quality.
(colourless, clear, free of sediments)
Filling water and make-up water must be pre-filtered (max.
pore size 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 per-
formance range (heat pump + boiler combination), flow tem-
peratures 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 hardness 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.
CAUTION!
!
!
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.
Minimum heating water flow rate
The minimum heating water flow rate through the heat pump
must be assured in all operating states of the heating system.
This can be accomplished, for example, by installing a dual dif-
ferential pressureless manifold.
The frost protection function of the heat pump manager is ac-
tive whenever the heat pump manager and the heat circulating
pumps are ready for operation. The system must be drained if
the heat pump is taken out of service or in the event of a power
failure. If heat pump systems are implemented in buildings
where a power failure cannot be detected (holiday homes etc.),
the heating circuit should be operated with suitable frost pro-
tection.
