RA2000 Thermostatic Operator, Built-in Sensor and Dial

Best ones bought so far and we’ve bought many for a Apartment complex

this unit was mounted vertical and only worked about three months.sure wish there was a model designed for a vertical application.

They work as I thought

Used with the compatible valve body https://www.amazon.com/gp/product/B005E0MEDM/ref=ox_sc_saved_title_4?smid=ATVPDKIKX0DER&psc=1 and a straight vent, this is a great solution to the problem of controlling heat in a steam heated building. You can use one at any or all radiators. We use it in our bedroom. It would be great in a common room as well. They use them in NYC apartment buildings to prevent tenants from using the windows to control heat. I assume shoppers may not find themselves searching on Amazon for this, but the price isn't bad at all. Really good quality. Highly recommended.
