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 and terminal strip

X3; 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 supply electric 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).

CAUTION!

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).

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. The mains

cable for the installed pipe heater must be laid and secured

in accordance with the valid standards and regulations.

7) All installed electric cables must have permanent wiring.

8) The heat circulating pump (M13) is connected to terminals

X2/N and X2/M13.

9) The DHW loading pump (M18) is connected to terminals

X2/N and X2/M18.

10) The brine or well pump (M11) is connected to terminalsX2/

N and X2/M11 and PE.

11) The return flow sensor is integrated into the heat pumps

and is connected to the heat pump manager via the control

line. The return flow sensor must be installed in the immer-

sion sleeve in the manifold only when a dual differential

pressureless manifold is used. The single-core wires are

then connected to terminals X3/GND and X3/ R2.1. Bridge

A-R2 (situated between X3/B2 and X3/1 when delivered)

must then be moved to terminals X3/1 and X3/2.

12) The external sensor (R1) is connected to terminals X3/GND

and X3/R1.

13) The domestic hot water sensor (R3) is included with the

domestic hot water cylinder and is connected to terminals

X3/GND and X3/R3.
