I custom build digital thermal shutdowns. Mine will now restore power after 15 minutes or if the temperature drops. You have to push a manual reset button and you get a digital temp controller (Ranco). The probe can be placed up to a few hundred feet way, unlike the capillary type temperature controllers with the 6 to 10 feet probe.
