Help needed bypassing HW, broken Potterton Ep2000 programer

[stephenmx50]

Hi people,

I have a broken (burnet out-long story) Potterton EP2000 CH/HW programer. I have taken off the control pannel to reveal the base plate, does anyone know how i can bypass the control to get the HW to fire up by connecting two of the terminals together..? if so whitch ones..?

On the base plate i have wires going to C D N L 1 3 4 5

I only need to get the Hot water going as i dont have an emursion heater. And dont want to blow the house up connecting the wrong ones!

Hopeing some of you clever guys can help, thanks in advance.

Any Potterton EP programmer should just clip onto the backplate without the need for re-wiring - you can get them from any decent plumbers merchant for about £50.

If you're competant at electrics,
L - live
1 - HW off
2 - CH off
3 - HW on
4 - CH on

put a link between L and 3 to get hot water
put a link between L and 4 to get heating
use the stats to control temperature

thanks guys for you fast replys-much appreciated Yes i intend to purchase a new programer and clip on the base plate but am not going to get one until next week, so want to by pass.

So if i connect the L and the 3 i should get the HW to fire UP? Thanks!

Yes, If you do that then the HW will be permenantly on (under thermostatic control of course).
