If  the  temperature  is  higher  than  30°C  and  the  humidity  is  higher
than RH 80%, the thickness of the insulation materials should be at
least  20  mm  to  prevent  condensation  on  the  surface  of  the
insulation.

Connecting the electrical wiring

7.9.1

About connecting the electrical wiring

Before connecting the electrical wiring

Make sure:

▪ The refrigerant piping is connected and checked

▪ The water piping is connected

Typical workflow

Connecting  the  electrical  wiring  typically  consists  of  the  following
stages:

1

Making  sure  the  power  supply  system  complies  with  the
electrical specifications of the heat pump.

2

Connecting the electrical wiring to the outdoor unit.

3

Repositioning the air thermistor on the outdoor unit.

4

Connecting the electrical wiring to the indoor unit.

5

Connecting the main power supply.

6

Connecting the backup heater power supply.

7

Connecting the user interface.

8

Connecting the shut–off valves.

9

Connecting the electrical meters.

10

Connecting the domestic hot water pump.

11

Connecting the alarm output.

12

Connecting the space cooling/heating ON/OFF output.

13

Connecting the changeover to an external heat source.

14

Connecting the power consumption digital inputs.

15

Connecting the safety thermostat.

Precautions when connecting the
electrical wiring

INFORMATION

Also  read  the  precautions  and  requirements  in  the
following chapters:

▪ General safety precautions

▪ Preparation

DANGER: RISK OF ELECTROCUTION

WARNING

ALWAYS use multicore cable for power supply cables.
