- The interface between the Genius system and the boiler is a relay, which is only switching the boiler ON / OFF for each of Heating / Hot Water. This would not directly cause the boiler to go into a fault mode. The steps above proved that the Dual Channel Receiver is not faulty and is doing what it is told to switch ON and OFF the boiler.
- Sometimes because the Dual Channel Receiver is not wired properly there is a loose wire. You will know this is the case if the light at the top left turns off. The normal status of the Dual Channel Receiver is the amber light which blinks every 2 minutes because is communicating with the system not because is disconnected! In a case of loose wire, we suggest to check the wiring or to seek advice from an Electrician.
Here is a video to help you to check the state of the Genius system.
