Hi Folks,
I currently have a Potterton Puma 80 which has made it to the grand old age of 19 and is still going strong (touch wood) even if it is somewhat on the noisy and most likely highly inefficent side!
Anway - it currently has an external electronic timeswitch for the central heating fitted - Landis & Gyr RWB270. I should add at this point that there is no room stat fitted, its just a timeswitch.
I wanted to replace it with a more functional timeswitch to allow 7 day programming.
I was looking at the Hortsmann C27 as it seems to be cheap enough and gets decent reviews, can anyone confirm if swapping one with the other will be pretty straightforward as far as wiring goes? Or would anyone suggest a different timeswitch?
Cheers!
