Ensure the safety and functionality of thermostats and energy sensors with this heavy-duty thermostat protector cover. Designed to prevent unauthorized access, vandalism, accidental damage, and tampering, it is an essential solution for maintaining control over temperature settings in public and high-traffic areas.

Constructed from clear, 1/8-inch thick poly-carbonate, this cover offers superior durability while ensuring visibility of the thermostat. It is specifically engineered for environments where abuse is a concern, such as waiting rooms, break rooms, restaurants, cafeterias, schools, and other public spaces.

Strategically placed ventilation holes allow optimal airflow for proper thermostat operation, while an inner wall prevents tampering with dials and levers using small objects. The built-in key lock ensures that only authorized personnel can adjust the settings, helping maintain energy efficiency and security.

Safety Technology International STI 9100 – Frequently Asked Questions

1) Will a thermostat protector cover fit over my thermostat, or do I need to check the size first?
Measure your thermostat before ordering. The STI Mini Thermostat Protector is the small size in the family, and the covers come in several sizes to suit different thermostat footprints, so the mini will not swallow a large programmable stat with a wide subbase. Check the height, width, and how far your stat stands off the wall, then match it to the mini. If your thermostat is a larger commercial unit, step up to a bigger cover in the range instead.
2) Does putting a clear cover over a thermostat make it read the room temperature wrong?
Ventilation holes are built into the cover so air keeps moving across the sensor and the thermostat reads normally. That is the whole reason these have a perforated body rather than a sealed box. The polycarbonate is clear as well, so the display and the setpoint stay readable without opening it.
3) How do I stop tenants and staff from changing the thermostat setting?
The mini thermostat protector locks over the stat with a key lock, so only whoever holds the key can open it and adjust the setting. There is also an inner wall inside the cover that blocks someone from reaching a dial or lever with a pen or a paperclip through the vent holes, which is the usual workaround on a plain cover. For a property manager fighting setpoint drift across a building, that combination is what actually holds the setting.
4) Is a key lock thermostat guard better than a plain snap-on cover for a school or restaurant?
For any space the public reaches, waiting rooms, break rooms, restaurants, cafeterias, classrooms, take the key lock version. A plain unlocked guard keeps hands off by accident only; anyone determined just lifts it. The keyed mini protector needs the key to open, so maintenance staff can adjust and nobody else can. Where the only concern is a mop handle or a cart bumping the stat, an unlocked guard is enough.
5) How tough is the polycarbonate on an STI thermostat guard? Will it crack if someone hits it?
The shell is 1/8 inch thick polycarbonate, an impact resistant plastic rather than brittle acrylic, and it is the same material class used for machine guarding and glazing shields. That thickness is what lets it take a shoulder, a ball, or a cart in a gym or corridor without shattering. It stays clear, so the stat remains visible after years of service.
6) Can I mount an STI thermostat protector outdoors or in a parking garage?
Indoor use. The mini thermostat protector is rated for indoor applications, so keep it to conditioned interior spaces: corridors, classrooms, dining rooms, break rooms. For an exposed exterior wall or an unconditioned open garage, this is not the right enclosure.
7) What does it take to install a thermostat guard on a drywall wall?
It mounts flush to the wall around the thermostat, so the install is drilling the backplate to the wall and setting the cover over the stat. On drywall you will want anchors sized for the fastener rather than driving into board alone, since the cover is what people push and pull on. The whole unit is light, half a pound, so the load is abuse rather than weight.
8) Do I get one thermostat cover or a case when I order the STI mini protector?
One cover per order, sold as a single count with its key lock. If you are standardizing a whole floor or a building, order a unit per thermostat.
9) Can I use this cover over something other than a thermostat, like a sensor or a small control?
It works over energy sensors and small wall mounted controls as well as thermostats, as long as the device fits the mini footprint and needs airflow. The perforated body and the clear polycarbonate mean a sensing device keeps working and a readout stays visible underneath. It is a cover only, not a control, so it adds no function to the device it protects.
