Ion™ System control

Don’t call it a thermostat -- mere thermostats simply don’t offer all of the features and functionality of the Ion™ System Control. Offering full command over a communicating comfort system, including temperature, humidity, ventilation, comfort scheduling, energy management and more, this is our most fully-featured control. Anywhere in the connected world, you are just a touch or a tap away from full system control with an internet-enabled device.
