Auto-Sequencing of AC Units with PLC

Auto-Sequencing of AC Units with PLC

Auto-sequencing of AC units is a process that automatically turns on and off multiple AC units in a sequence to maintain a desired temperature while saving energy. This process is typically controlled by a Programmable Logic Controller (PLC), which is a digital computer used for automation.

Benefits of Auto-Sequencing AC Units

  • Energy Efficiency
  • Improved Comfort
  • Reduced Maintenance
  • Increased Reliability
