The temperature sensors to be connected to the heat pump man-
ager must correspond to the sensor characteristic curve illus-
trated in Fig.7.2 on pag. 10. The only exception is the external
temperature sensor included in the scope of supply of the heat
pump (see Fig.7.3 on pag. 10)

7.5.2 Mounting the external
temperature sensor
The temperature sensor must be mounted in such a way that all
weather conditions are taken into consideration and the meas-
ured value is not falsified.
 Mount on the external wall on the north or north-west side
where possible
 Do not install in a "sheltered position" (e.g. in a wall niche or
under a balcony)
Not in the vicinity of windows, doors, exhaust air vents,

external lighting or heat pumps
 Not to be exposed to direct sunlight at any time of year
Sensor lead: Max. length 40 m; min. core cross-section
0.75 mm²; external diameter of the cable 4-8 mm.

7.6 Electrical connection

7.6.1 General
All electrical connection work must be carried out by a trained
electrician or a specialist for the specified tasks in accordance
with the
 installation and operating instructions,
 country-specific installation regulations (e.g. VDE 0100),
 technical connection conditions of the energy suppliers and
supply grid operators (e.g. TAB) and
 local conditions.
To ensure that the frost protection function of the heat pump
works properly, the heat pump manager must remain connected
to the power supply and the flow must be maintained through the
heat pump at all times.
The switching contacts of the output relay are interference-sup-
pressed. Therefore, depending on the internal resistance of the
measuring instrument, a voltage can also be measured when the
contacts are open. However, this will be much lower than the line
voltage.
Extra-low voltage is connected to controller terminals N1-J1 to
N1-J11; N1-J19; N1-J20; N1-J23; N1-J24 and the terminal strips
X3. If, due to a wiring error, the line voltage is mistakenly con-
nected to these terminals, the heat pump manager will be de-
stroyed.

7.6.2 Electrical Installation

1) The five-core electrical supply cable for the output section of
the heat pump is fed from the heat pump meter via the utility
company blocking contactor (if required) into the heat pump.
The mains cable is connected at the heat pump switch box
using terminals X1: L1/L2/L3/N/PE.
The enclosed mini-grip bag contains four links that have to
be connected to terminal X1 (L1-L10, L2-L20, L30-L3, N-N0)
as shown in the circuit diagram (see appendix). There is no
need for these links if two separate five-core supply cables
are used (see appendix).
An all-pole disconnecting device with a contact gap of at
least 3 mm (e.g. utility company blocking contactor or power
contactor) as well as an all-pole circuit breaker with common
tripping for all external conductors must be installed in the
power supply (tripping current and characteristic in compli-
ance with the device information).
ATTENTION!
Only applies to the SIW 6TES:
Ensure the rotary field is clockwise when connecting the mains cables (if
the rotary field is not clockwise, the heat pump will not work properly, is
very loud and may cause damage to the compressor).
Only applies to the SIW 8TES and SIW 11TES:
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).
