[QUOTE="brummydave, post: 287333, member: 18490"] yeah a plumber friend of mine only does honeywell and loves them to bits. It's a 230v contact, it's been installed for a few months, it's a thermostat so is only designed to control a single channel - the heating. The system is actually quite complex, it has a combi boiler providing instant hot water to the kitchen only and being used as a system boiler to three zones through a 3 channel horstmann progammer. zone one is house heating (ten rads up and down), zone two is under floor heating (kitchen) and zone three is an unvented megaflo cylinder for hot water to showers etc. zone 1 has the honeywell stat, zone two has a siemens programmable stat (not as clever as the honeywell) and zone three has a cylinder stat. I thought the honeywell was sparking like it did due to loose connections, but no. So any other thoughts? I'll try honeywell, denmans, cef, ebay etc for a repair or new transmitter but i'm more concerned what caused the boom! [/QUOTE]
