Customer has Honeywell T4039V1001 line voltage stat which Honeywell lists as obsolete with no replacement available. Now what? Anyone know a way around this?
It would help to know what kind of unit your working with, but a possibility could be to install a transformer relay at the unit, junction/wire nut the line voltage at the old stat, and run a new standard t-stat and wire. It would be helpful to know more about the system.
Thanks for the input. It is a fan/coil system. I finally got through to a person at Honeywell and they suggested TB6575, which looks like it will be a go.
