Tado wireless thermostat connected but no heating
I have a small problem. I received my Wireless Tado Room Thermostat today and a guy tried to fit it for this evening. On completion of the installation, I have found myself with no heating (but I do have hot water)
Here is all the information I have.
The boiler is a Intergas HRE
The Wireless receiver which is connected to the boiler appears to be working fine, all the lamps are lit (except the one with an error/storing). The Tado app can see all the Tado Radiator Valves, the bridge and the receiver near the boiler.
When I increase the room temperature on the app or via the thermostat nothing happens, the radiators remain cold.
The app is communicating with all sensors
