When the 2 port valve is connected to REL3:

• Connect the neutral wire (blue) of the valve to the “N” of the

REL3 connector.

• Connect the live wire (brown) of the valve to the “L” of the

REL3 connector.

• Connect the earth wire (yellow/green) of the valve to the

earth of the REL3 connector.

• Electrically insulate the red and grey wires of the valve as

they are not used.

When the 2 port valve is connected to REL4 or 5:

• Connect the neutral wire (blue) of the valve to the “N” and

the live wire (brown) of the valve to the “L” of the REL4 or 5

connector.

• Connect the earth wire (yellow/green) of the valve to the

earth of the REL3 connector.

• Electrically insulate the red and grey wires of the valve as

they are not used.
