The Copeland 985-CP1A-3A 100 PSI Low-Pressure Controller: The controller is usually used in HVAC systems for the regulation and monitoring of low-pressure conditions. Besides, this controller is made from aluminum material; it is strong and highly reliable in performance for inclusive -40°F up to 250°F, hence suitable for application in a variety of HVAC systems. This low-pressure controller activates controls, which serve to bring the pressure back to the set point once it is held consistently above a set point for a certain period. It protects the system from damage, besides offering optimum performance due to the realization of low-pressure conditions and initiating compensating controls like compressor start-up or opening up the pressure release valves. Copeland 985-CP1A-3A controller application covers most HVAC equipment, air conditioners, and refrigeration equipment. They impart such advantages as better energy usage, improved system security, and lower maintenance costs.
