SMART Equipment Control Firmware – Johnson Controls
Johnson Controls has released version 3.4 of its SMART Equipment Control Firmware. The new SMART equipment firmware incorporates a new feature known as Continuous Reset Single Zone Control™ (CRSZ Control). Unlike the typical Single Zone Variable Air Volume (VAV) system operation, company reps said the CRSZ Control provides precise control of space comfort while maximizing energy savings.
Company officials also said the CRSZ is a control feature that allows field configuration of a single zone VAV operation and is a unique Johnson Controls feature for the HVAC market. It offers added comfort and energy savings by balancing compressor staging and fan speed to deliver stable zone temperature and humidity control.
