Hi All
Seem to have a small problem with my aged central heating system.
Although the central heating comes on when switched to constant, it doesn,t seem to come on when its on the timer, checked the programme, turned it off, even had the thing off the wall to see if it would reset, couldn,t see a reset button.
The only thing i can see is that it says (hi) on the display, is this the problem and is it terminal, alas i don,t have the instructions for the controller.
HELP regards
Al
