Hi all,

I have an ideal C24 boiler which is connected to a nest thermostat. The hot water works however the central heating does not work. I discovered when I removed the inbuilt timer connection to electronic board and turned heating on using nest the central heating works. Is this a faulty inbuilt timer or could it be something else. I am afraid of keeping it disconnected incase it deactivates any fail safes.
