This controller can control both a heating and cooling device.  Alternatively, it can control a heating or a cooling device.

In my opinion the original ITC-308 was and is a game changer as far as homebrew temp controllers.  In comparison to available controllers available at the time the ITC-308 was released, it offered loads more features, including dual stage control, for a fraction of the price.  Game changer!  The addition of Wi-Fi control and monitoring to this great controller has made a great temp controller even better.  Check out our Hands on Review of the ITC-308.  That includes a section on the WiFi version.

I’m aware of two different Amazon listings for the ITC-308. From time to time other listings pop up including combos. This listing appears to be the ITC-308 + WiFi
