In the end I went for a Tado system, switched out the the two Honeywell wired thermostats with the Tado replacements. leaving the boiler time controller in place with heating now on constant and existing HW control, I did want to replace this unit but not sure of any real benefit other than to...

Thanks for this stem, that's excellent. Yes my installer definitely didn't follow this terminal numbering convention, probably a good idea to have it made so, then i can have a wiring diagram that makes sense for future fault finding. Now just need to decide on a system, was looking at the Hive...

Just dawned on me... what a cracking idea to stick the single zone unit in the airing cupboard, never gave that a thought, why wire it down to where the time controller is when it doesn't need to be there, solves all my problems, thanks stem

Thank you all so much for your help, as they say it's good to talk, it's really not such a daunting or complicated a task as I was thinking it was going to be and can give me the option to basically have any smart thermostat system installed. Any thoughts on the best system out there, Hive...

The wire I'm short of is a separate switch wire for the 2nd heating zone rather than the common wire i have now from the time controller. My current thermostats act as a switch so i just need to connect the two wires together, the switching would now controlled by the smart thermostats, which...

Wish my connection strip was a bit tidier, but looking at this wiring diagram I'm short of one wire from my boiler to airing cupboard that would let me do what I'd like to do, giving a separate feed to that circuit. I now understand what's needed, hopefully a spare core there that can be used...

OK thanks for the feed back, at least I know what system i have now, an S Plan Plus all makes sense now :unsure: I'm thinking turning it into a two zone system is not an easy option unless something can be done with any spare cores not being used. Are there any options to replace a S Plan plus...

Although thinking about it more, I'd assumed the hive wired thermostats still talk to receivers and just switch the existing wires, don't think this is the case, so would need to go wireless and connect existing thermostat wires together, which again takes it away from a 2 zone system.

I have a Potterton boiler controlled by a ST6400C that i was considering upgrading to a smart heating system. I'm struggling to understand due to the way my system is wired what i could replace it with? I have 2 CM707 thermostats, one for ground floor and the other for 1st and 2nd floors. The...
