5.4 Electrical connection

5.4.1

Power supply

The power supply is connected to the X1 terminals in the device
via a cable provided by the customer. L/N/PE
5.4.2

Bus connection to the heat pump manager

Cooling operation mode is added to the existing heat pump
manager by an electronic connection between the heat pump
manager and the cooling station (software update may be
necessary).

NOTE
If used with reversible birne-to-water heat pumps, the "A-N17.1" bridge
on the passive cooling station must be removed.

5.5 Reversible brine-to-water heat pumps

In connection with reversible brine-to-water heat pumps an
additional sensor (R24) must be installed in the common return

6 Description of functions

The installation and operating instructions for the heat pump
manager and the project planning documentation must be
observed. In particular, the descriptions of the cooling functions
from the installation and operating instructions for the heat pump
controller apply in connection with the following supplements:
Cold is generated by switching the primary cooling pump (M12)
on or off. The heat pump compressor is not active and is
therefore available for DHW preparation.
The parallel operation of cooling and domestic hot water
preparation is activated in the heat pump manager settings.
Setting Parallel Cooling - DHW: Yes
also see the heat pump manager operating instructions
NOTE
Ensure that the special hydraulic installation requirements are fulfilled for
the parallel operation of cooling and DHW preparation (see project
planning documentation)
If parallel operation is not activated on the heat pump manager,
the requests will generally be processed according to the
following priority (in specific cases deviations are possible):

Connection is established on site with a screened 2x0.5mm²
cable at a maximum length of 50m. The connecting cable must
be connected according to the relevant connection matrix for the
heat pump manager:
The N17.1 and N17.3 extension modules have the addresses 1
and 3 respectively. The addresses are preset on the extension
module DIP switches.
of the brine circuit. The sensor must be connected to terminal X3-
R24.

In the following cases, the primary pump for cooling (M12) will be
shut down for safety reasons:
 The flow temperature falls below a value of 7°C
 Activation of the dew point monitor at vulnerable points in
the cooling system
The cooling circulating pump (M17) operates continuously in
cooling operating mode.
The various functions of the primary circulating pump (M12,
primary pump for cooling operation) and the heat circulating
pump (M13) can be set on the heat pump manager (see
installation and start-up instructions for technicians). Depending
on the hydraulic integration, the setting determines whether
during cooling operation two primary circulating pumps (M11 and
M12) run parallel or whether the heat circulating pump (M13)
also undertakes distribution during cooling operation.
