- If there is no existing boiler programmer then the Dual Channel Receiver must be wired into the boiler as if it were an external programmer. See wiring diagrams provided by the boiler manufacturer to confirm the wiring guides provided with this installation manual.
- If you remove the existing wired house thermostat out of the control circuit (recommended), it must also be removed from the control in the wiring centre, otherwise the Single Dual Channel receiver Receiver will have no control over the boilerheating.

Hot Water Time & Temperature addon (Electric Switch)
...
| Info |
|---|
- The temperature in a hot water tank will stratify, and so the Electric Switch will measure a different temperature dependent on where on the tank it is located. It is recommended to use the location of the existing Cylinder Stat or a pocket built into the Hot Water tank.
- The existing cylinder stat should be set to a temperature above the temperature required on the app. and above 60º to protect against legionella.
- For appliances rated up to 2kW use minimum 1.0mm2 flexible conductors. For appliances rated up to 3kW use minimum 1.5mm2 flexible conductors. Heat resistant flexible cable must be used if connecting the Electric Switch to an immersion heater.
- The Electric Switch is rated to 13A and must not be wired to an immersion heater with a higher rating. This will result in damaging the Electric Switch and voiding the warranty!
