harrycatcat1 Posted May 18, 2015 Report Share Posted May 18, 2015 This programmer has seen better days and it looks like the clock has been pulled off or something has. My question is would you change it like for like (if they still make this sort) or would you change it for a different sort digital? if so which one and where would you get it from?

Yellow Bear Posted May 18, 2015 Report Share Posted May 18, 2015 Change for a digital - far better - even B&Q cheapy is better than the one shown Quote Link to comment Share on other sites More sharing options...
aga man Posted May 18, 2015 Report Share Posted May 18, 2015 Most plumbers merchants or MKM building supplies or even b and q etc will stock good twin channel timeclocks, most of witch will have fitting /cross reference guides with them. To make it easy this model is a direct replacement for yours http://www.heatingcontrolsonline.co.uk/siemens-landis-staefa-rwb29-programmer-p-43.html Quote Link to comment Share on other sites More sharing options...

djgeoff Posted May 18, 2015 Report Share Posted May 18, 2015 as aga said most of them have cross ref info with them. when i did ch wiring years ago i used Honeywell gear and the timer was st699b and according to my book it is a replacement for yours (landis gyr RWB2) . but there will be other makes that will do the same job. the image is for the Honeywell st699b and a Y plan installation if it helps Quote Link to comment Share on other sites More sharing options...
harrycatcat1 Posted May 19, 2015 Author Report Share Posted May 19, 2015 Thanks very much for the info please accept my apologies for not respondig sooner but its rather hectic at the moment. I am trying to get all my jobs out of the way in the next 3 or 4 weeks and then hopefully get out shooting. I am 3/4 way though renovating this old house.
