Suggestions for replacement room stat

[RC1]

Currently have a 4 wire satchwell tl25 on a very old kingfisher potterton 2 boiler. gravity fed hw and pumped ch. have replaced the timer with a newer 7 day programmable drayton lp722

any ideas on suitable upgrade for the room stat? i know that most digi stats have 2 wire terminals so will likely have redundant earth and neutral?

from what i know a programmable stat may be not be required given limitations of my system but its increased size means less making good after i remove the old one

would a honeywell cm907 be suitable or anything else?

I have the honeywell and although i can't say if it suitable for your system, I highly rate it

Now i just need to know if it is compatible! Good to know its a good 'un though

What sort of system do you? Is it fully pumped or gravity hot water and pumped heating?
