Honeywell Chronotherm iv Plus power cuts on and off


There's a trouble shooting guide here, you need to check for the presence of 24V when it goes blank, and trace back to where it's disappearing (I assume it is losing the 24v, if not you'll need to go through the installer setup or read on...
My first thought would be to check the wiring which has been touched last if it started doing that after you had coil replaced.
As an aside I'm not sure which model you have but if it has batteries you should replace them (I don't think it does have batteries but not seen a model iv so I'm unsure)
