Mars mars-70220 Universal Thermostat Guard

Product Description

The MARS mars-70220 is a universal thermostat guard designed to protect wall-mounted thermostats from tampering, accidental damage, and unauthorized adjustments. The assembly includes a clear plastic cover and ring paired with a white base, giving installers a clean, professional finish while keeping the thermostat visible and accessible for authorized service. This type of guard is a standard fixture in commercial and light-commercial HVAC installations where thermostat setpoint control and vandal resistance are required. Licensed HVAC technicians and building maintenance professionals install this component as part of routine thermostat service or system commissioning.

Thermostat guards are commonly specified in schools, offices, retail spaces, multi-family residential buildings, and light-industrial facilities where occupant access to thermostat controls must be restricted. The clear cover allows the thermostat display to remain readable without opening the guard, which supports quick visual checks during building rounds or inspections. The white base provides a neutral wall-mount appearance compatible with standard commercial interior finishes.

Key Features

• Clear plastic cover and ring allow thermostat readability without removing the guard
• White base provides a clean, neutral appearance on standard wall surfaces
• Universal design accommodates a wide range of wall-mounted thermostat form factors
• Plastic construction resists corrosion in typical indoor HVAC environments
• Discourages unauthorized thermostat adjustments in shared or occupied spaces

Compatibility

Designed as a universal-fit replacement or new-installation thermostat guard suitable for a broad range of wall-mounted residential and commercial thermostats.

Installation Notes

Installation is typically performed by a licensed HVAC technician or qualified building maintenance professional. Power to the HVAC system should be shut off at the disconnect or breaker before handling thermostat wiring or removing an existing thermostat cover. Secure the base to the wall using appropriate fasteners for the wall material, then snap the cover and ring into place over the installed thermostat. Verify the cover closes fully and the thermostat controls are not inadvertently depressed or obstructed after installation.
