Replacing an EPH R27 controller with a Drayton Wiser Multi-room Kit 2

[tk_2kand1]

Hi,

I am looking for advise. I am looking to replace an EPH R27 controller with a Drayton Wiser Multi-room Kit 2. Has anyone done this? Is it just a matter of taking off the existing EPH controller from the wall plate and replacing it with the Wiser Controller?
Do i need to change wiring in the wall plate in any way?
Thanks

Yes you should be able to swap the Wiser for the EPH. Multi room kit, are you planning on smart TRVs?

Hi, yes planning on the smart TRVs as well. Any wiring changes required in the back plate? Thanks

Sorry, but may I clarify which model EPH R27 you have?

The stock R27 supports two heating zones, whereas the R27-HW has a single heating zone and hot water control.

The Drayton Wiser multi-room kit 2 is for a single heating zone + HW - the multiroom relates to the smart radiator stats.
If you have two heating zones, you may need the kit 3, or rewire the zone valves to create a single zone and utilise more smart TRV's.

Hi, i have a EPH R27 E2132C. I have the ability to run the central heating on its own. Or have the boiler heating the hot water on its own. I have manual TRVs at the moment. Hope this helps. And its one heating zone i.e. upstairs and downstairs rads heat at the same time. Photos attached

OK, all good!

IT IS the dual heating zone controller, but has been set up to be used for a single zone and hot water.
The Wiser should be a straight swap.
