Herpstat thermostats are great but I would get a better model then the intro bc it doesn't have the safety features. If your room gets below 80 at anytime you will need another heat source for the cold side which means you will need a herpstat 2. I just use a uth for both the hot and cold side and set my herpstat at 92 for hot side and my cold side is set to 85 that way I never have to worry about if my room gets to cold. You could use the heat emitter as your cold side heat source as well but you will still need a herpstat 2.
