Discuss Which Danfoss model is this heating control? in the DIY Plumbing Forum area at PlumbersForums.net
Thanks Gasmk 1. I'll come clean: I know next to nothing about plumbing/CH. I've moved into a property that's been vacant for a while, and I need to replace this unit like for like (I read it has to be the exact same model otherwie it won't sync with the boiler?). Is there anyway of finding out which model it is without turning it on? (the insides are rusty as hell with battery leak damage).
I would replace it with a honeywell T3 or 4
Would that mean replacing the wireless reciever on the boiler as well?
If you're referring just to the battery compartment corrosion we can see in the photo, it might clean up with a bit of scraping, brushing and wiping, and assuming the metal tabs are not corroded through it might still work! If it was me I'd give that a shot first. You need to scrape the battery tabs so that the parts that touch the ends of the cells are showing clean bare metal.
