Meet the ECO2S Temperature Sensor
Let’s face it, most garages have cold spots and don’t ever seem to maintain an even temperature throughout. With the ECO2S+ Temperature Sensor, your ECO2S+ heater knows exactly where that cold spot is and works smarter to keep the entire room comfortable. Just place it on a wall or shelf and get the right temperature, right where you want it.
KB ECO2S+ Works with NEST
Since KB ECO2S+ comes standard with a provision for adding an optional 24V thermostat for remote temperature control, setting up a Nest WiFi thermostat or any 24V WiFi thermostat is simple and easy. Controlling your Garage Heat has never been easier. Comfort is a click away.
Safe Comfort For Large Spaces
Patented Smart Limit Protection (U.S. Patent #6,748,163 B2) automatically shuts power off to the heater in an abnormal event and must be manually reset for safety.
Spiral Steel Fin Heating Element For Maximum Heat Exchange
The metal sheath element is copper brazed with spiral fins then molded into a coil configuration. This combination produces the heat transfer while eliminating the potential for hot spots by positioning the element in the maximum airflow stream.
