Review on π‘οΈ Honeywell THX9421R5021WW: Revolutionizing Thermostat Technology with Definition by Bryan Turner
2-wire installation only
A separate interface module must be ordered for this job as it is a 2-wire connection only. Don't think you can just trade it in for yours. If you need this one they sell another item that comes with this thermostat, interface module and 3 sensors. It's a lot cheaper than buying them individually.
Pros
- Red LINK Wireless
Cons
- Small parts
