Quest's Patented Smart Adaptive Control HVAC Economizer Algorithm

Adaptive Free Cooling for your Critical Facility

Through the Quest Controls’ patented free cooling learning algorithm customers have achieved energy savings of up to 25%.

  • Available on RSC 1000, ESB2 , Model 600 and Model 400 platforms.
  • The algorithm optimally adjusts the outside air temperature free cooling setpoint automatically at any site, based on the success of maintaining shelter temps. Automatically adjusting for:
    • Changes in site heat load (ie. add/remove network equipment).
    • Changes in HVAC performance (ie. dirty filters/airflow changes).
  • Free cooling setpoints are available to management systems for performance reporting.
  • Critical Infrastructure teams have visibility to ensure maintenance accountability, settings are correct, and economizers are working optimally.
The Algorithm controls economizers for HVAC systems allowing them to maximize the amount of time outside air is used to maintain the temperature in each zone, thereby saving significant energy costs through free cooling.
  • Reduce required worktime at the site to adjust dampers and economizer controls
  • Save energy by reducing HVAC compressor run times.
  • Ensure optimum operating conditions for critical equipment.
  • Reduce carbon footprint.
  • No additional training requirements.
