1. The appliance MUST have a permanent Live/Neutral/Earth connection. The pump must be connected to the appliance as shown.
2. Set parameter 5700 to '2' for one heating circuit ­ see section 11.3.k.
3. The rest port of the 3 port valve needs to be connected to the central heating circuit so that the valve is driven to the DHW position. It is most likely that the three port
valve on an existing primary circuit will have to be turned round.
NOTE: It is not possible to operate a second heating circuit with a W­Plan system.
