Most older fully pumped houses have the boiler, fused spur and prog at the boiler downstairs, the pump and motorized "heating valve" upstairs in the airing cupboard, sooooo, there is only a SWL to the pump N E and live the the valve running from downstairs, so that is 4 core, to change to an S plan with two valves means 5 cores to the airing cupboard, so the Honeywell Rf pack isn't any help, am I missing something here ? because if it already had 2 mot valves the wiring would already be there, so I don't see the benefit of the RF room and cyl stat !
