Non-programmable 2H/1C thermostat

This Emerson 1F79-111 thermostat provides non-programmable control for heating and cooling systems. It supports two stages of heat and one stage of cool. The digital display shows current temperature and system status. It is designed for low-voltage 24VAC hardwired installations.

Hardwired 24VAC terminal connections

The unit requires a hardwired connection to a 24VAC power source using the C terminal. Terminal designations include R, C, W2, Y, G, O/B, E, and L for system and fan control. System switching offers Heat, Cool, Off, and Emergency modes. Fan switching provides Auto and On settings for air circulation.

Steady-state temperature regulation

Under sustained load the thermostat maintains the setpoint by cycling the configured heating or cooling stages. Without battery backup the display and logic rely on continuous 24VAC power. The absence of automatic changeover means the installer sets the system mode manually for the season. No remote sensing or humidification control is available for extended runtime adjustments.
