Resideo TG512A1009 Thermostat Guard

Resideo TG512A1009 Thermostat Guard

As a direct replacement for the BB3001, the Resideo TG512A1009 Versaguard Universal Thermostat Guard is the industry standard for securing wall-mounted controls in high-traffic commercial or institutional environments. Designed to eliminate unauthorized setpoint adjustments, this large universal thermostat guard features a tamper-resistant lock with a unique double-wall construction. The heavy-duty clear acrylic cover allows for immediate inspection of your Honeywell Home thermostat or other large-scale controls without compromising security, while the opaque polystyrene wallplate ensures a stable, professional mount on any flat surface or exposed junction box.

For technicians concerned with sensor accuracy, the TG512A1009 is engineered with high-flow venting in the guard base. This ensures continuous airflow as if the thermostat were unshielded, maintaining precise temperature sensing for TH5000, TH6000, and TH8000 Series devices. Whether you are performing a vertical or horizontal mount, the included tumbler lock—complete with two keys—remains captive until fully engaged. This HVAC thermostat lock box is an essential upgrade for schools, rentals, and offices to prevent equipment misuse and reduce unnecessary service calls caused by tenant tampering.

  • Universal Compatibility: Sized to fit most major brands and specifically compatible with Honeywell TH8000, TH6000, and TH5000 series.
  • Tamper-Proof Design: Includes a high-security tumbler lock and key set where the key is only removable in the locked position.
  • Optimized Airflow: Precision-engineered vents allow for accurate temperature detection, preventing short-cycling or sensor lag.
  • Flexible Installation: Designed for easy integration with existing systems or new builds, supporting both vertical and horizontal orientations.
  • Dimensions: Internal clearance of 5-7/8" H x 8-3/8" W accommodates large-format digital thermostats.

Common Questions:

Will this thermostat guard fit a Honeywell T6 Pro?
Yes, the TG512A1009 is a large-format universal thermostat guard and provides ample clearance for the T6 Pro series as well as older, bulkier mechanical models.

Can it be installed over an existing thermostat?
The clear cover and ring base allow for streamlined installation over most thermostats without requiring you to disconnect wiring or remove the subbase from the wall.

How does this assist with energy management?
By installing a locking thermostat cover, facility managers can maintain strict setpoint control, preventing occupants from setting extreme temperatures that increase utility costs and wear on the HVAC system.
