External connections to the heat pump

These are the external connections that must be made for the heat pump:

Power supply 3-phase:

The power supply is connected to terminals L1, L2, L3, N and PE. In

the event of a possible phase sequence fault the heat pump will trip the alarm

3-phase incorrect

See more information in the section

What to do if a fault occurs

Power supply 1-phase:

The power supply is connected to terminals L, N, and PE.

Mixing valve on the heating circuit:

If a second heat curve with a mixing valve is to be used,

the mixing valve is connected to terminal block SV1.

External main pump in the heating system G1

(P1): The external main pump must be

connected to the terminal card in those cases a bypass is required. The pump is connected to
terminal P1.

Return sensor radiator T1 (GT1)

: Must always be connected. Connect to terminal GT1.

Outdoor sensor T2

(GT2): Must always be connected. Connect to terminal GT2.

Hot water sensor T3

(GT3): Is connected if the heat pump is to produce hot water. Connect

to terminal block GT3 X on the terminal card. On the LW model this sensor is already
connected on delivery.

Mixing valve sensor T4

(GT4): Is connected when a mixing valve for a second heat curve is

to be used. Connect to terminal GT4.

Room sensor T5

(GT5): Is connected if room sensor infl uence is required.
