Hello I have a Veissman boiler with a wireless thermostat.
The batteries were recently changed in the thermostat and since that time it has not communicated with the boiler. A red LED light flashes on the receiver.
I can work the boiler using it's controls and a grey button on the receiver but obviously the heating isn't controled thermostatically.
I can see similar threads have been posted before and I have tried switching the boiler off and on with no success.
Any ideas please??
John.
