Salty Dog two
It fits straight in place of the old one.
So far so good, the old one was playing up. Auto set time etc - excellent. Easy to program - well for the wife anyway.

I would not recommend
I had to buy this unit to replace a unit of the same model and make which broke down. It appears from a quick search on google and YouTube that this model is faulty and breaks down after a while. Honeywell never r plied to my request for support. I Would NOT recommend Honeywell because they don’t have customer service
