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 ca-

bles 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 in-

stalled in the power supply (tripping current and character-

istic in compliance 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).

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 switch box of the heat

pump via terminals 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 rea-

son, it should be tapped upstream from the utility blocking

contactor or be connected to the household current, as im-

portant protection functions could otherwise be lost dur-

ing 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 terminal X3/A1.

CAUTION! Extra-low voltage! The contactor is installed in

the electrical distribution system. Mains cables for the

installed heaters must be laid and secured in accordance

with the valid standards and regulations.

4) All installed electric cables must have permanent wiring.

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

(ground) and X3/R1.

7.6.3 Connecting an electronically

regulated circulating pump

Electronically regulated circulating pumps have high starting

currents, which may shorten the service life of the heat pump

manager. A coupling relay is therefore installed or must be in-

stalled between the output of the heat pump manager and the

electronically regulated circulating pump. This is not necessary

if the maximum permissible operating current of the heat pump

manager of 2 A and the maximum permissible starting current

of the heat pump manager of 12 A are not exceeded by the

electronically regulated circulating pump or a relevant approval

has been issued by the pump manufacturer.

ATTENTION!

It is not permitted to connect more than one electronically

regulated circulating pump via a relay output.
