Robertshaw 801-22 Thermostat

The Robertshaw 801-22 Thermostat is a rugged, line voltage heating thermostat engineered for high-performance temperature regulation in residential, commercial, and industrial environments. Featuring a Single Pole Single Throw (SPST) configuration, this unit is the designated updated version for Robertshaw 801, offering enhanced compatibility for retrofitting electric baseboard heaters, radiant heat systems, and electric furnaces. Utilizing a dependable bimetal temperature sensing element, it maintains tight thermal differentials within a standard range of 50°F to 90°F (10°C to 32°C).

Built for the professional contractor, the Robertshaw 801-22 is designed for J-Box housing compatibility, which streamlines field installation and ensures compliance with local electrical codes. The non-inductive electrical rating supports 120V, 240V, and 277V AC applications at 22 Amps, making it a versatile universal replacement thermostat for most single line break heating profiles. Its mercury-free design eliminates specialized disposal requirements, while the integrated positive-off switch ensures an absolute system shutdown in the lowest setting for increased safety during maintenance or seasonal transitions.

• Universal Retrofit: Functions as a direct drop-in for the legacy Robertshaw 801 and most major brand electric heat thermostats.
• High Amperage Capacity: Rated for up to 22 Amps of heating power, suitable for demanding line voltage circuits.
• Precise Sensing: High-quality bimetal strip improves overall thermal response and system efficiency.
• Visible Diagnostics: Includes a convenient temperature display for at-a-glance monitoring of ambient conditions.
• Installation Efficiency: Vertical mounting and standard lead wire connections reduce time on the job site.

• Is this compatible with 24V low-voltage control systems? No, this is a line voltage thermostat specifically intended for 120V/240V/277V direct power applications.
• Can this be used for cooling applications? This specific model is designed for heating applications only; cooling requirements typically require an 803 series equivalent.
• Does this require a neutral wire? For SPST line voltage installations, the thermostat breaks one side of the power line; refer to your local electrical code and the wiring diagram for specific circuit requirements.
