Q: I want to replace Wickes programmer RWB252 will RWB29. Fit the old backplate therefore no rewireing Many Thanks

A: Yes it will.
Q: I have an old Landys & Gyr RWB200 timer unit. The RWB 29 is a straight replacement. Will I need to do any different wiring or is it just plug in and go. Please advise. Best regards< jon

A: The RWB29 is a straight swap just plugs on the existing backplate.
Q: How is the old RWB9 removed from the backplate to allow the fitting of a new RWB29 unit?

A: The are two screws at the bottom that will need loosening. The unit will then hinge up off the backplate. Remember to switch the electric off first.
Q: Can this be used as a direct replacement for a RWB2 programmer without changing the backplate or wiring?

A: Yes it can.
Q: I have a Siemens RWB2E controlling a back boiler. I see from a previous answer that the RWB29 is a suitable digital replacement but does it make any difference that it is linked to a back boiler? As you will gather, I'm not an electrician or plumber!!

A: It doesn't make any difference. It's still a suitable replacement.
