White-Rodgers F29-0231 Plastic Guard

The White-Rodgers F29-0231 is a professional-grade clear plastic thermostat guard designed to eliminate unauthorized adjustments and protect sensitive climate controls in high-traffic environments like offices, churches, and rental properties. This model features a dual-mounting configuration, including both a ring base and a solid wall mounting plate, providing maximum versatility for field installations. Built with high-impact polycarbonate, this heavy-duty enclosure ensures long-term durability while maintaining full visibility of the thermostat display for quick status checks. The F29-0231 is cross-compatible as a direct replacement for the 190-056 and BTG-DK models, fitting most standard White-Rodgers controls except for the 90 Series Blue models.

For the service technician, the thermostat lockout cover includes a keyed lock with two keys, preventing temperature tampering that often leads to excessive energy consumption or equipment strain. The vented design allows for optimal airflow circulation, ensuring the internal sensors maintain accuracy without thermal lag. With inside dimensions of 7-1/16" L x 4-1/8" H x 2-1/4" D for the ring base, this HVAC security cover is a standard truck-stock item for maintaining facility control and reducing nuisance service calls related to unauthorized setpoint changes.

Common Questions

Will this guard fit my specific White-Rodgers thermostat?
The F29-0231 fits most standard White-Rodgers horizontal thermostats. However, it is not compatible with the larger 90 Series Blue touchscreen models.

Can I mount this vertically if my thermostat is oriented that way?
While designed primarily for horizontal footprints, the mounting holes allow for flexible orientation; however, internal dimensions should be verified to ensure the thermostat fits within the 4-1/8" height constraint.

What happens if I lose the keys?
This unit uses a standard White-Rodgers key set (part number F145-0999), making it easy for facility managers to maintain access across multiple units with a master key.
