10.6 W-Plan with DHW cylinder sensor
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 W-Plan system.
