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 secondary circuit (R2) installed
(NTC-10)
Return temperature primary circuit (R24) installed (NTC-10)
Flow temperature secondary circuit (R9) installed (NTC-10)
Flow temperature primary circuit (R6) installed (NTC-10)
7.4.1 Sensor characteristic curves
The temperature sensors to be connected to the heat pump man-
ager must correspond to the sensor characteristic curve illus-
trated in Fig.7.1. The only exception is the outside temperature
sensor included in the scope of supply of the heat pump (see
Fig.7.2)
Fig. 7.1:Sensor characteristic curve NTC-10
Fig. 7.2:Sensor characteristic curve NTC-2 according to
DIN 44574 Outside temperature sensor
7.5 Electrical connection
A standard 5-core cable is used to connect the heat pump to the
power supply.
The cable must be provided on-site. The conductor cross section
is selected in accordance with the power consumption of the heat
pump (see attachment Device Information) and the applicable
VDE (EN) and VNB regulations.
An all-pole disconnecting device with a contact gap of at least
3 mm (e.g. utility company blocking contactor or power contac-
tor) as well as a 3-pole circuit breaker with common tripping for
all external conductors must be installed in the power supply for
the heat pump (tripping current in compliance with the device In-
formation). When installing a residual current device, a version
that is suitable for DC components that could occur due to elec-
tronic equipment, for example, must be used (RCD type B).
The relevant components in the heat pump contain an internal
overload protection.
When connecting, ensure that the incoming supply has a clock-
wise rotating field.
Phase sequence: L1, L2, L3.
ATTENTION!
Ensure that there is a clockwise rotating field: With incorrect wiring the
starting of the heat pump is prevented. A corresponding warning is
indicated on the display of the heat pump manager (adjust wiring).
The control voltage is supplied via the heat pump manager.
A 3-pole line must be laid for this in accordance with the
electrical documentation. Further information on the wiring
of the heat pump manager is available in the heat pump
manager operating instructions.
A shielded communication line(J-Y(ST)Y ..LG) (not included
in the scope of supply) connects the heat pump manager
with the µPC2 installed in the heat pump. More detailed in-
structions can be found in the heat pump manager operating
instructions and in the electrical documentation.
NOTE
The communication cable is necessary for the function of air-to-water
heat pumps in outdoor installation. It must be shielded and laid
separately from the mains cable.
7.5.1 Demand sensor connection
The demand sensor R2.2 (NTC 10) is included with the heat
pump manager. It must be installed depending on the hydraulics
used (see Appendix Chapter 3 on p. VII).
If a demand sensor is not connected, the second heat generator
can not be controlled with the heat pump manager in the event of
an interruption in communication either.
NOTE
The return sensor R2 installed in the heat pump is active when the
compressor is running and must not be disconnected.
