Emerson's Liebert Mini-Mate line of cooling, air filtration and humidity control devices are usually installed above dropped ceilings in rooms where computer networks or other valuable equipment are stored. They come in a variety of configurations but are typically controlled by a standard Liebert thermostat, or microprocessor, which you can program and monitor. Familiarize yourself with the Liebert thermostat's basic controls, and let the system do the work for you.

Scroll up and down with the keypad buttons to set the temperature at your desired level. Press "Enter" again.
Use the up and down arrows on the keypad from the "Setpoint" menu to change the humidity, high and low temperature and humidity alarms, and other specialized settings.
