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.
4. The DHW set point on the THINK Controller must be the
same as the thermostat set point on the cylinder. If this is not
done the DHW temperature may not be achieved or the
E
recovery time will be increased.
