I have an ACL Lifestyle LP241 programmer which operates both my hot water & central heating. The problem is the programmer will work with the hot water, it will call for heat to the cylinder when I turn it to on and when on a timer(twice).
However the programmer does not control the central heating even when I turn it to either on or timer (twice). To operate my central heating I need to turn the room stat (Drayton RTS1) to a temp above current room temp. The heating will only come on when controlled by the room stat, even when programmer is at 'off'.
I have only recently identified this problem as the CH was off for the whole summer. I also did recently replace the RTS1 room stat, as the previous RTS1 was faulty.
