## Long description

ProBase TOS-3-1U is a 19-inch 1U rack-mount thermostat with an integrated LCD display designed to monitor and control temperature inside equipment cabinets and server racks.

Advantages
The ProBase TOS-3-1U combines compact, rack-friendly dimensions with an easy-to-read LCD and straightforward front-panel controls, enabling precise temperature monitoring and simple operator adjustments without opening the cabinet.

How to use
Install the thermostat into an available 1U position in a standard 19-inch rack using the included mounting hardware. Connect the unit to the cabinet power and any controlled devices according to the installation requirements. Use the front-panel LCD to view the current temperature, and adjust the setpoint and operating mode via the front controls to define the desired temperature range.

Usage recommendations
Place the thermostat in a representative rack location—typically at mid-height or where temperature-sensitive equipment is concentrated—to obtain accurate readings. Avoid locating the sensor immediately adjacent to high-heat sources or direct airflow from fans. Periodically check the display and test thermostat outputs during maintenance to ensure reliable temperature control of rack-mounted equipment.
