OK.  The next steps will almost certainly work if the thermostat isn’t faulty.

1. Remove the batteries from the thermostat.

2. Power off the heating so that the receiver/relay box has no power.

3. Wait 10 minutes.

4. Power up the receiver.

5. Insert brand new batteries into the thermostat.

6. Carry out the re-binding procedure - see the following video for guidance.
