Covidhair Posted January 7, 2022 Share Posted January 7, 2022 these have been sold. I have two C4 thoermostats for sale. I have used these in my house, but have taken them off my system for some Nest thermostats. Both work well. There is some graying in the display on each which has been present since they were installed by my dealer. Seems like they all have this, but in the name of transparancy, they you are. It's is visible in the piccs. Some pics are attached, but let me know if you want to see more. Make me an offer for one or both. Link to comment Share on other sites More sharing options...
