SI 130TUR+
7.4.4 Hydraulic distribution system
The compact manifold and the dual differential pressureless
manifold function as an interface between the heat pump, the
heating distribution system, the buffer tank and, in some cases,
even the hot water cylinder. A compact system is used to sim-
plify the installation process, so that a lot of different compo-
nents do not have to be installed individually. Further informa-
tion can be found in the relevant installation instructions.
Compact manifold
The return sensor can remain in the heat pump, or should be in-
stalled in the immersion sleeve. The remaining empty space be-
tween the sensor and the immersion sleeve must be filled com-
pletely with heat transfer compound.
Dual differential pressureless manifold
In order for the heating circuit pumps of the generator and con-
sumer circuits to supply the flow to the return sensor, this must
be installed in the immersion sleeve of the dual differential
pressureless manifold.

7.5 Electrical connection

7.5.1 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 con-
nected 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-
suppressed. 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 to N1-J26; N17-J1 to N17-
J4; N17-J9; N17-J10 and terminal strips X3 and X5.1. If, due to
a wiring error, the line voltage is mistakenly connected to these
terminals, the heat pump manager will be destroyed

7.5.2 Electrical installation

1) The electric supply cable for the output section of the heat
pump (up to 4-core) is fed from the electricity meter of the
heat pump via the utility blocking contactor (if required)
into the heat pump Connection of the mains cable to the
control panel of the heat pump via terminal X1: L1/L2/L3/
PE.
An all-pole disconnecting device with a contact gap of at
least 3 mm (e.g. utility blocking contactor or power contac-
tor) and an all-pole circuit breaker with common tripping
for all external conductors must be installed in the power
supply for the heat pump (tripping current and characteris-
tic in compliance with the device information).

ATTENTION!
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).
2) The three-core electric supply cable for the heat pump
manager (heating controller N1) is fed into the heat pump .
Connection of the control line to the control panel of the
heat pump via terminal X2: L/N/PE.
Details on the power consumption of the heat pump are
listed on both the product information sheet and the type
plate.
The (L/N/PE~230 V, 50 Hz) supply cable for the heat pump
manager must have a constant voltage. For this reason, it
should be tapped upstream from the utility blocking con-
tactor or be connected to the household current, as impor-
tant protection functions could otherwise be lost during a
utility block.
3) The utility blocking contactor (K22) with 3 main contacts
(1/3/5 // 2/4/6) and an auxiliary contact (NO contact 13/
14) should be dimensioned according to the heat pump
output and must be supplied by the customer.
The NO contact of the utility blocking contactor (13/14) is
looped from terminal strip X3/G to connector terminal X3/
A1. CAUTION! Extra-low voltage!
4) The contactor (K20) for the immersion heater (E10) of
mono energy systems (HG2) should be dimensioned ac-
cording to the radiator output and must be supplied by the
customer. It is controlled (230 V AC) by the heat pump
manager via terminals X2/N and X2/K20.
5) The contactor (K21) for the flange heater (E9) in the hot
water cylinder should be dimensioned according to the ra-
diator output and must be supplied by the customer. It is
controlled (230 V AC) by the heat pump manager via termi-
nals X2/N and X2/K21.
6) The contactors mentioned above in points 3, 4 and 5 are
installed in the electrical distribution system. Mains cables
for the installed heaters must be laid and secured in ac-
cordance with the valid standards and regulations.
7) All installed electric cables must have permanent wiring.
8) The heat circulating pump (M13) is activated via the con-
tact N1-J13/NO5. The connection points for the pump are
X2/M13 and X2/N. When using pumps where the switch-
ing capacity exceeds the output, a coupling relay must be
interposed.
9) The auxiliary circulating pump (M16) is activated via the
contact N1-J16/NO9. The connection points for the pump
are X2/M16 and X2/N. When using pumps where the
switching capacity exceeds the output, a coupling relay
must be interposed.
10) The domestic hot water circulating pump (M18) is acti-
vated via the contact N1-J13/NO6. The connection points
for the pump are X2/M13 and X2/N. When using pumps
where the switching capacity exceeds the output, a cou-
pling relay must be interposed.
11) The brine or well pump (M11) is activated via the contact
N1-J12/NO3. The connection point for the pump is on
contactor K5:2/4/6. A coupling relay is already integrated
in this output.. If an additional well pump is used, the pro-
tective motor switch at the site must be checked and re-
placed if necessary.
Connection of the well pump mains cable on the heat
pump's control panel via terminal X1: L11/L21/L31/PE.
