Hi all,
My central heating runs off an old oil boiler which uses a Siemens RWB2E controller and doesn't have a room thermostat anywhere. By the looks of it the controller only controls the heating as the hot water is an immersion heater with a separate supply.
There are three cables to the controller. The first is the main supply which is fed directly from a junction box in the airing cupboard upstairs, the second goes to the CH pump and the third goes to the boiler itself.
I would like to replace the controller with a new smart one and was wondering whether there is a direct replacement available? I have seen the likes of Nest with a controller and a room thermostat but would a thermostat be of any use in my set up?
Is there any real benefit of adding the immersion heater to the controller? Looks like it might have been connected in the past but is now fed directly from the same JB as the controller (with no isolator etc).
What might be the best model for me to look at?
The kitchen is being rewired by the spark in a few weeks and I could get him to tidy this up too so it would be good to have it available for when he comes.
Regards
