Ion™ System Control

The Ion™ System Control is the premium control center for premium Tempstar® communicating HVAC equipment. When you add an Ion­™ System Control to a compatible variable speed furnace, fan coil, split system, or Ion System compatible geothermal product (when available), you will enjoy longer heating and cooling cycles at lower fan speeds for a more consistent temperature throughout your home. By adding a multi-stage, or 2-stage outdoor unit, you will enjoy extra benefits which include better humidity and temperature control as well as a more energy efficient comfort system. When paired with Ion™ Zoning controls, the Ion™ System Control allows you to create up to 8 zones of customized comfort. The Ion™ Zoning system does not require a bypass damper, leaving air temperature (LAT) sensor, or field-installed power transformer. Always install the latest version of software to enable all features of the system. Over-the-Air software updates for Wi-Fi® models connected to the Ion server are automatically downloaded. Software updates via Micro SD are available at
