Itc-301TB by Inkbird.  Digital Dual Stage Pre-Wired Temperature Controller with 12 Timers.

My contact at Inkbird has said that timers start when a certain temperature is reached.

Dual stage means that the Itc-310TB can control both a heating and cooling device.  Alternatively, it can control a heating or a cooling device.  This controller displays in Fahrenheit and Centigrade.
