Details:

These cost $130 to $170. I had it installed for the in-floor electric heat in my bathroom. This is a model ADG4 manufactured by. I replaced this thermostat for one that is WI-Fie compatible.

This is a used line voltage thermostat. Because it is used a little over one year and marked my price $50. I thought may have ruined it but after fixing my short worked fine for the year and a half that was installed. I installed it in 2024 and has worked fine.

Also included is a new in floor sensor I used the one that was already installed.
