Hi, I've recently installed a Tado system to my Worcester Greenstar 37CDi boiler. It all appears to be set up correctly according to tech support, but when the boiler should be off, it is still heading radiators which don't have TRVs installed. Something is keeping it on and Tado tech support don't know why. I've removed the previous thermostat MT100RF. They've advised me to get someone in to check it out but I've already spent a fortune and don't want to throw good money after bad. I'm on the verge of taking it all back but thought I'd try this first. All help gratefully received!!
