I currently have a Honeywell Smartfit connected to on oil boiler/pump in an S Plan arrangement, works well but the programmer has started to play up and I would like some more smart control.
I am thinking about getting a Nest and I know it is not directly upgradeable from Smartfit.
The CH is fine as it is all together with the boiler and pump in my garage so I can replace valves with 5-wire valves but the HW is upstairs in my airing cupboard with the HW tank. Cureently there are 2 cables, a 2 core for the HW therostat and a 3 core (only 2 being used) for the 2-port valve. I'm looking for advice on what to get to upgrade the HW controls using the bits and pieces I currently have. For example I coud use both the 2 core and the 3 core cable for a 5 wire HW 2-port valve and then maybe a wireless thermostat?
Thanks
