Hi Guys hope you can help, I have a wet underfloor heating system and have 6 zones, the problem I'm having is one of the zones is getting warm even though the master thermostat/controller is turned off, the pump is not being switched on so is not circulating through the system. I have an 'Ideal Esprit eco' combi boiler which works well only 2 years old. The room stat failed in the room which is getting warm and was replaced with a similar replacement. Hope someone can shed some light on the problem for me.
Thanks
Thanks
