Robertshaw 802-22 Thermostat

The Robertshaw 802-22 is a professional-grade line voltage thermostat engineered to provide precise manual temperature control for electric baseboard heaters and radiant systems. As the direct 802 replacement, this rugged 120V unit features a double-pole single-throw (DPST) switch configuration, ensuring a positive "OFF" position for mechanical system shutdown and enhanced safety during maintenance. Designed with bimetal temperature sensing technology, it delivers a +/- 2°F control accuracy across a 50°F to 90°F range, making it a reliable solution for residential and commercial heating retrofits. The mercury-free construction requires no leveling, while its vertical, J-Box compatible mounting ensures a streamlined installation for HVAC contractors. Whether you are servicing existing industrial heating controls or upgrading outdated 120V stats, the 802-22 offers the durability and bimetal thermal performance required for high-demand environments.

• Universal Compatibility: Specifically designed as a versatile retrofit for most electric heat models, including the legacy Robertshaw 802 series.
• DPST Positive Off: The double-line break switch ensures a full system cut-off, meeting strict safety codes for electric heating applications.
• Enhanced Accuracy: High-performance bimetal sensing provides tighter thermal differentials than standard mechanical controls.
• Contractor-Friendly Install: Fully compatible with standard 2" x 4" electrical boxes, featuring simplified wiring for 120V AC non-inductive loads.
• Environmental Safety: Modern mercury-free design eliminates special disposal requirements and simplifies the job site cleanup.

Is the Robertshaw 802-22 a direct replacement for the original 802?
Yes, the 802-22 is the updated technical successor to the original 802 model, maintaining the same 120V line voltage specifications and mounting footprint.

Can this thermostat handle 240V or 277V applications?
While the 802 series is often rated for multiple voltages (120/240/277V AC), always verify the specific electrical rating on the unit's nameplate to ensure compatibility with your field voltage and inductive load requirements.

Does this unit require a neutral wire for installation?
As a DPST heating thermostat, it breaks both sides of the line for safety. Ensure all wiring conforms to local electrical codes regarding "positive off" mechanical breaks.
