Hi all First time post here, after searching the net for ever I have not been able to find any diagrams or instructions to help me replace my Honeywell gt699b thermostat with the Nest v3. Not sure what setup I have as there is a small boiler down stairs in the kitchen and a hot water tank...

Hi all, We have a Worcester Bosch Greenstar 30CDi Combi boiler, and are installing the Honeywell Evohome system with HR92 wirelessly controlled TRVs. My plan had been to have a TRValve fitted to the radiator in our hallway, where there currently isn't one as the thermostat is based there. In...

Hi, All working well with custom home screen and text but how do you add a control device? I imagined I could just add a button to activate an output to open a gate or something but can't for the life of me find how to program it in? Is there any information on editing the whole thing? I know...

hi My Honeywell st9400 appears to be fried since a power cut yesterday. It's showing an internal fault and from a bit of googling that seems terminal. As it is I've been thinking of getting hive for a while but wanted to know if, as well as replacing the thermostat, does it also replace the...

Hey all, I've read numerous threads on here about installing Nest 3rd generation into the home (such as this good one - kudos to @stem). I'm really tempted to do this myself but my wife will kill me if I screw up the heating at this time of year! If anyone can give me some pointers, it would...

Hi, I have an old Honeywell analog thermostat in the hall way and the dial keeps falling off it. I am not sure if I have aligned it correctly when putting the dial back on. Is there a specific way of doing it? Also, what temperature should the dial read when the thermostat clicks on? Thanks...
