Description
The Daikin-McQuay 349956814 Low-Limit Pressure Control is a specific controller that is used to measure low pressure in HVAC systems and is calibrated at 0.15 inches w.c. This control mechanism is used to achieve better operating conditions on diverse HVAC equipment, including air-handling units, and refrigeration equipment. It works by sensing pressures and then switching the compressor on and off to control the pressure in the system to ensure that the system is efficient without producing dangerous pressures. The primary advantages of using this low-limit pressure control are to save energy, as it eliminates compressor work during low-demand time, and to increase system durability, as it shields the system from low-pressure damage.
