Safe. Stable. Smart.


The HELIO Smart Controller is a reliable midrange choice between commercial and hobby-grade heater controllers. It houses a circuit board processor that continually communicates with a titanium sensor to ensure consistent temperature accuracy. When a temperature difference is detected, it immediately cuts power to your heating device(s) and emits an audio alarm. The controller has two power lines to control two heating elements at once, up to a combined total of 1000 watts. If the heating element(s) of your choosing have their own controlling systems, you can create up to four independent temperature readings to provide safety in redundancy.
