I don't know the model number of the AUBE thermostat that I have. I was told that it was designed for hydronic floor heating, it has been in my shop now going on 14 years and works great. When the room temp calls for heat, it turns the pump on and the pump runs for a short time and it will shut off and allow the water temp to recover and then turn back on automatically, it will continue to do this until it reaches the set point. there are 4-5 dip switches that you can setup to use it for different applications. If I recall correctly I got mine from Menards. Hope this helps.
