Help! No heating!
About a year ago we moved into a new property and inherited an Ideal Logic combi boiler connected to a Tado smart heating system.
As it's now getting colder, we're noticing a lack of central heating at present. The boiler has a message of "room stat or timer off" and there's no heat coming through to the radiators. The Tado box connected to the boiler is flashing lights to indicate that it's connected to the wireless thermostat unit and the app appears to suggest that the Tado system is requesting heat from the boiler but there's nothing being produced and the boiler isn't firing to provide heating. The hot water is fine so we know the boiler is working correctly.
I've tried to reset the boiler and even gone so far as to power it off at the mains and back on again but this hasn't had any effect. I've re-paired the wireless thermostat but the behaviour is the same as before, I can see that the wireless receiver unit has a 4 short flash followed by a gap sequence that I understand suggests that it's paired correctly. I've also removed all smart schedule configuration to leave a single time block heated to 18 degrees and have attempted to boost heating to 25 degrees to make the heating trigger, but again no effect noted.
If anyone has any ideas, or has experienced this problem before, I'd love to hear from you! Selection of screenshots and images attached to demonstrate position.
