Replace Landis & Gyr RWB2

[lbton]

Hello.
The timer on my old Landis Gyr programmer has not been working for sometime (HW / CH has to be manually turned on) and I need to replace it.
Can any advise which model would be the most forward to replace it with please?

Thank you all.

Or, for a slightly more informative answer, your RWB2 is a dual channel programmer (CH and HW), that fits on an 'industry standard' backplate.
This means replacement is very straightforward.
To replicate what you have already, they even have a modern equivalent...

However, if you want to upgrade to something modern and smart, choices like a dual channel Hive, or Drayton Wiser, may also fit directly onto the old backplate with no wiring changes (or simply matching the wires to the new backplate, if it doesn't quite fit).
There are also plenty of other alternatives, depending on the features you want, and the price you're willing to pay.

Something else to watch for, when you remove the old unit, there may be a small switch at the back set to either 'Gravity' or 'Pumped' - this is important to note to aid setting up the new programmer.

Good luck

Turn the power off before removing/refitting the programmer!
