Emerson Climate Technologies 1F80-361 Programmable Thermostat

Product Description

The Emerson Climate Technologies 1F80-361 is a single-stage digital programmable thermostat designed for residential and light commercial HVAC systems. It operates on 24-volt or millivolt system wiring, making it compatible with a broad range of heating and cooling equipment. The 5-1-1 day programming schedule allows separate temperature settings for weekdays, Saturdays, and Sundays. A clear digital display and straightforward interface allow technicians and end users to configure schedules and set points without additional tools or software. This thermostat suits standard low-voltage control applications and installs in place of most existing single-stage thermostats.

The 1F80-361 is intended for single-stage heating and cooling systems in residential and light commercial settings. Typical applications include forced-air gas furnaces, central air conditioning systems, and heat pumps with auxiliary heat. The 5-1-1 schedule structure gives building occupants independent weekend control, which is useful in applications where Saturday and Sunday occupancy patterns differ from the weekday routine. It is not rated for multi-stage or variable-capacity equipment.

Installation Notes

Installation is typically performed by a licensed HVAC technician. Power down the HVAC system at the breaker and, for gas systems, shut off gas supply before removing the existing thermostat. Follow NEC low-voltage wiring guidelines when connecting control wiring to the subbase terminals. Do not apply line voltage to the thermostat terminals, as the unit is rated for low-voltage control circuits only.
