Hi. I have a switchmaster 900 timer running a Barlo 65F boiler but it is not flexible enough in that it doesn't allow heating and water to be switched at different and various times of the day. Can anyone recommend an electronic programmable timer compatible with the 900 and are there any 'crib sheets' for this kind of changeover? I have been told the Drayton LP722 is a compatible and more sophisticated replacement. How easy is this? My DIY skills are average to mediocre as the name suggests.

Thanks

Hi Andy

Welcome to the forums,hope you enjoy
The back plate on the 900 is quite standard now and many programmers will fit onto it,there is a quite extensive range of Drayton ones to choose from and are very user friendly,there should be a wiring diagram on the back of your 900 so always double check wiring

Hi and thank you very much. Is the backplate the connecting plate/circuit and do you know of any diagrams that make the transition from the switchmaster to the LP722 easy?

hi andy welcome to the forums

the back plates on programmers are all standard nowadays so should be a straightforward swap and as puddle says double check wiring is correct

Thanks Steve. When I get the new programmer I will be able to compare the two and go from there.
