Cheap Honeywell Aube Telephone Controller with 2 Outputs - CT240-01

This device connects to your Aube thermostat via a two wire interface. It worked exactly as described, but I couldn't figure out how to use this with other equipment other than my thermostat. I also had to disable my answering machine - but I'm not sure if I could get both to work at the same time. I probably should have read the owner's manual a little further. All things said, this worked exactly as described and was easy to use.Get more detail about Honeywell Aube Telephone Controller with 2 Outputs - CT240-01.
