Q: I have a 30 year old Landis & Gyr RWB2. Will the Siemens RWB2E be a suitable straight replacement or is there another option ?

A: Yes, it will plug onto the existing backplate for a simple swap.
Q: Is this interchangeable with a busted Horstmann 425 Tiara?

A: You will need to change the backplate.
Q: I currently have a Siemens RWB29. Can I replace it with a RWB2E to the existing backplate?

A: Yes you can.
Q: My rwb2e Siemens controller is stuck in the on position and clock not moving round. I have ordered a new programmer from you - will it be easy to swap them over? Some of your answers to other questions say you can use the existing backplate - is this the same in this instance?

A: Yes you simply: 1) Switch off the electric 2) Remove the old timer from the backplate 3) Fit the new timer onto the backplate 4) Switch on the electric. A very simple 5-minute job.
Q: I have a Landis and Gyr Type RWB 4 controller fitted to a Glow-worm 85-100 boiler - will this unit replace the RWB 4 or do you have an equivalent replacement available please?

A: You will need to install the RWB2E on the wall next to the boiler and link it into the back of the RWB4. There is nothing that will go onto the existing backplate.
