The ACI A/LOCKING COVER is a locking thermostat guard cover designed to mount to a base plate and restrict unauthorized access to thermostat controls. The cover measures 6.06 inches by 5.06 inches by 2.63 inches, providing a secure enclosure suited for commercial and light commercial environments where temperature control tampering is a concern. HVAC technicians and facilities maintenance personnel install this type of guard as part of building comfort control systems to prevent occupants from adjusting setpoints without authorization.
This thermostat guard cover is appropriate for use in offices, schools, hotels, retail spaces, and other commercial buildings where thermostat setpoint protection is required. It mounts to a compatible base plate, making installation straightforward for technicians already familiar with thermostat hardware. The locking design helps maintain consistent HVAC operation by keeping occupants from altering programmed settings.
Designed as an OEM-style replacement or supplemental accessory for thermostat guard systems that use a separate mount-to-plate installation method. No specific compatible model numbers were provided in the product data.
Installation is typically performed by a licensed HVAC technician or qualified facilities maintenance personnel. Before installing or removing the cover, ensure the thermostat and associated low-voltage wiring are not disturbed and that the base plate is securely fastened to the wall surface. Follow local building codes and the thermostat manufacturer guidelines when installing guard hardware over existing controls.
