ok i've just fitted a honeywell s plan system.
The problem is when you select the heating to come on only, i.e the hot water selector is in the 'off' position, both the l.e.d's come on for hot water and heating?? and the same happens when you select hot water only. whatever you select, or set the timer too, both hw and ch come on??
i've triple checked the wiring, and tried the programmer with just the live and neutral wired in (just to power programmer), so is it a faulty programmer?
cheers for anyones thoughts!!
