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.
