Key specs explained for this unit

HVAC Stages: 2H/1C, 1H/2C Conv; 2H/1C Heat Pump

This rating defines the number of heating and cooling stages the thermostat can control. Two heat and one cool stage suits most standard homes with conventional furnaces or basic heat pumps. If your system has more complex zoning or multiple stages, you may need a higher-tier model. Check your HVAC manual to ensure your equipment matches these limits before purchasing.

C-Wire Requirement: Power Extender Kit sold separately

Many older HVAC systems lack the common wire needed for continuous power. This device allows installation without one by using a separate Power Extender Kit. You must purchase this kit separately if your home does not have a C-wire. This option simplifies DIY installation for older systems, but you need to budget for the additional component.

Room Sensor Support: Supported (sold separately)
