Classic 80 Series thermostat for single-stage

The Emerson 1F80-361 is a low-voltage digital thermostat designed for residential heating and cooling equipment with one heat stage and one cool stage. It operates on 24VAC power and includes battery backup to retain settings during power interruptions. The 2.2 square inch display shows temperature and programming status clearly for everyday household use.

5-1-1 scheduling holds steady across the week

The thermostat follows a 5-1-1 program structure with four temperature settings per day, repeating the same schedule Monday through Friday and allowing separate Saturday and Sunday profiles. Temporary overrides and temperature holds let occupants adjust comfort without erasing the underlying program. System switching between heat, cool and off plus fan auto-on control keep the HVAC cycle consistent during extended operation.

24VAC wiring with basic terminal set

Terminal designations C, G, O/B, RC, RH, W and Y cover conventional single-stage gas, oil, electric and heat-pump configurations without auxiliary heat or humidification. The lack of Wi-Fi capability, remote sensing and programmable fan means the device cannot integrate with smart-home platforms or respond to external temperature sensors. Builders needing multi-stage control, humidity management or app-based access must select a different model.

Questions about this item

How much power does the 24 VAC thermostat draw when it runs continuously?

The unit operates on a standard 24 VAC circuit with single-stage heating and cooling, so its power draw is minimal and typical for low-voltage HVAC controls.

Which wiring terminals must my existing system provide for the 1F80-361 to function?

Your system needs C, G, O/B, RC, RH, W and Y connections to match the thermostat's terminal designations.

Will the 1F80-361 control a two-stage furnace or heat pump that I already own?

No, the thermostat supports only one stage of heat and one stage of cool, so multi-stage equipment will not be fully utilised.
