English
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 active
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. The heating circuit should be operated with a suitable
frost protection if heat pump systems are implemented in build-
ings where a power failure can not be detected (holiday home).

7.3 Heat source connection

The following procedure must be observed when making the
connection:
Connect the brine pipe to the heat source flow and return of the
heat pump.
The hydraulic integration diagram must be adhered to.
ATTENTION!
The supplied dirt trap must be inserted in the heat source inlet of the heat
pump to protect the evaporator against the ingress of impurities.
ATTENTION!
It is recommended that the brine circuit side be equipped with the flow
rate switch available as an option.
The brine must be produced prior to charging the system. The
liquid must have an antifreeze concentration of at least 25 % to
ensure frost protection down to approx. -14 °C.
Only monoethylene glycol or propylene glycol-based antifreeze
may be used.
The heat source system must be de-aerated and checked for
leaks.
ATTENTION!
The brine solution must contain at least a 25 % concentration of a
monoethylene glycol or propylene glycol-based frost protection, which
must be mixed before 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:
 Outside temperature sensor (R1) supplied (NTC-2)
 Return temperature heating circuit (R2) installed (NTC-10)
 Return temperature primary circuit (R24) installed (NTC-10)
 Flow temperature heating circuit (R9) installed (NTC-10)
 Flow temperature primary circuit (R6) installed (NTC-10)

The temperature sensors to be connected to the heat pump man-
ager must correspond to the sensor characteristic curve illus-
trated in Abb. 7.2 auf S. 6. The only exception is the outside tem-
perature sensor included in the scope of supply of the heat pump
(see Abb. 7.3 auf S. 6)
