10.10 S-Plan with 2nd Heating Circuit
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 ‘3’ for two heating circuits - see section
11.3.k.
3. To control the second heating circuit a second THINK
Controller is required – this is available as an optional extra. For
guidance on installing the second THINK Controller see section
11.3 paragraph k.
Use either a cylinder sensor or thermostat as in section 10.8&9.
