Q: The heating is not working even though the flame is showing.

The thermostat and receiver will need re-pairing:

• Ensure the receiver switches are set to Auto and On.
• Turn OFF the boiler at the mains switch on the wall for 30 seconds.
• Turn the boiler back on – the receiver lights should briefly flash, then settle on a solid red light.
• Quickly flick the receiver switch from its ON position to OFF and back to ON, to get the red flashing light.
• On the thermostat, hold the test / pairing button down to get SYNC10 on screen.
• Ensure you are at least a metre away from the receiver.
• After a few seconds the red flashing light should turn solid.
• Hold the test / pairing button down again to get back to the main screen.
