Product: SMART Equipment Control Firmware

Description: In the latest version of this product — version 3.4 — a new feature known as Continuous Reset Single Zone Control™ (CRSZ Control) has been added. This patented control feature provides precise control of space comfort while maximizing energy savings. It allows field configuration of a single-zone VAV operation. The feature also balances compressor staging and fan speed to deliver stable zone temperature and humidity control. The CRSZ Control operates with the minimum fan speed needed to maximize energy savings and comfort, based on the percentage of demand for cooling. It uses an algorithm that focuses to maintain space/zone temperature with changing load characteristics. This system is a specifiable feature that is ideal for a wide-range of applications.
