3 Operation and maintenance

NOTE

The unit is operated via the control panel

of the heating and heat pump controller

( operating manual of the heating and heat

pump controller).

3.1 Energy and environmentally-

conscious operation

The generally accepted requirements for an energy-

conscious and environmentally-conscious operation of

a heating system also apply to use of a heat pump.

The most important measures include:

● Nounnecessarilyhighowtemperature

● No unnecessarily high domestic hot water

temperature (note and follow local regulations)

● Do not open windows with just a gap or tilt open

(continuous ventilation); instead, open wide for a

short time (shock ventilation).

● Always ensure that the controller settings are

correct

3.2 Maintenance

Wipe down the outside of the unit only using a damp

cloth or cloth with mild cleaning agent (washing-up

liquid, neutral cleaning agent). Do not use any harsh,

abrasive, acid or chlorine-based cleaning products.

6.2 Electrical connection

The electrical connection is established via the switch

box (apart from the load of the electric heating ele-

ment).

The wall-mounted controller is connected on site

according to the following scheme:

5

1 Heat pump

2 Control voltage

3 Bus cable (shielded)

4 Compressor load

5 Wall-mounted controller

6 Control voltage

7 Compressor load

8 Electric heating element load

9 Sub-distribution

1. Stripthesheathingoallcablestotheexternalloads

before laying in the cable gland of the switch box.

2. Pull in the cables and conductors and carry out

electrical connections in accordance with the

terminal diagram.

 Terminal diagram for the respective model.

„Terminal diagram“, from page 13

 Illustration of the compnents of the wall-mounted

controller, page 6.

3. Fasten return ow sensor (1) to the heat-

conducting pipe of the return (2) to the heat pump

using cable ties and thermal compound.

1 Returnowsensor

2 Return (leading to the heat pump)

6.3 Establish the electrical

connections between the heat

pump and the wall-mounted

controller

1. Route supply cables from outdoor unit into house.

2. Install Bus cable plug (3) and compressor load

cable plug (4).

3. Apply control voltage (2) in wall-mounted

controller and heat pump

4. Install electric heating element load cable (8) in

sub-distribution (9).

NOTE

The control panel of the heating and heat

pump controller can be connected to a com-

puter or network using a suitable network ca-

ble, enabling the heating and heat pump con-

troller to be controlled remotely from there.

If such a connection is required, install a

shielded network cable (category 6, with

RJ45 connector) during the electrical con-

nection work and connect it parallel to the ex-

isting control cable of the heating and heat

pump controller.
