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.

Enjoy the comfort of your home with our programmable thermostat that can enhance energy efficiency with humidity control during sticky summer months and 7-day temperature scheduling. If you have a heat pump and furnace as part of your home comfort system, the thermostat allows dual fuel management to switch from electric operation to gas heating when needed.

Programming your home comfort is a breeze with the Heil programmable thermostat that offers 7-day temperature control, and heating- and cooling-stage capable for customized comfort. It can also manage dual fuel heating and features auto changeover between heating and cooling for a thermostat that's easy and convenient.
