- 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 Dual Channel Receiver will not have control over the heating.
- Inside the door on the Dual Channel Receiver are 2 labels to display which button controls which part of the heating. When wiring the Dual Channel Receiver, check that the wiring matches these labels.
