White-Rodgers 179-1 Thermostat

The White-Rodgers 179-1 is a professional-grade line voltage thermostat engineered specifically for high-demand HVACR applications. Built with a heavy-gauge steel dustproof case, this SPDT (Single Pole Double Throw) control handles heating only or cooling only duties with industrial reliability. It is an ideal solution for managing fans or water solenoids on heating and cooling convectors. The hydraulic action element ensures the unit remains unaffected by motion, allowing for flexible mounting on a 2" x 4" vertical box or flush-to-wall without the need for precise leveling. Operating within a 55°F to 95°F temperature range, it features a fixed 3°F differential to prevent frequent equipment cycling, extending the lifespan of your 120V to 277V systems. For contractors managing industrial climate control where mechanical durability is non-negotiable, the Emerson White-Rodgers 179-1 provides the rugged manual thermostat performance required in heavy-duty environments.

• Heavy-Duty Construction: Encased in a rugged, dustproof steel housing designed to withstand harsh mechanical rooms and industrial sites.
• No Leveling Required: The internal hydraulic element functions correctly regardless of orientation, simplifying line volt thermostat installation.
• Versatile Electrical Compatibility: Rated for 120VAC, 240VAC, and 277VAC, eliminating the need for relays or motor starters in many cooling setups.
• Precise Temperature Control: A fixed 3 degree differential ensures stable thermal regulation between 55 and 95 degrees Fahrenheit.
• SPDT Switch Logic: Provides flexible wiring options for either "break on rise" (heating) or "make on rise" (cooling) configurations.

Is the White-Rodgers 179-1 suitable for baseboard heaters?
Yes, as a line voltage mechanical thermostat, it can control electric baseboard heaters, provided the amperage draw does not exceed its 22A non-inductive rating at 240V.

Can I use this thermostat for both heating and cooling simultaneously?
No, while the SPDT switch allows it to be wired for either heating or cooling, it is a single-stage control designed for heating only or cooling only operation per application.

What are the mounting requirements for this unit?
The 179-1 is designed to mount directly onto a standard vertical 2" x 4" electrical box or can be surface-mounted flush to the wall.
