Tempro Line Voltage Thermostats are essential components used in Commercial HVAC (Heating, Ventilation, & Air Conditioning) applications to control & monitor temperature in various systems. These devices are designed to work with line voltage systems, which typically operate at higher voltages, such as 120V or 240V.

Additionally, Tempro Thermostat Guards are found in many commercial settings to prevent tampering hands from adjusting thermostats overall reducing energy in these settings.

Both Tempro Line Voltage Thermostats & Guards are crucial components for maintaining temperature control, comfort, & energy efficiency in HVAC systems. Proper installation & use of these devices contribute to the overall performance & reliability of heating & cooling equipment, promoting a comfortable indoor environment while safeguarding against unauthorized changes.
