CV-EX System Overview
The Auto-Zone CV-EX system is used in buildings that because of their size or design
requirements have more than thirty rooftop units. Standard CV-EX systems can facilitate
up to sixty constant volume units. With the addition of a CV-EX Loop Expansion Kit, an
additional thirty units may be added to the CV-EX system. Two loop expansion kits can
be added to the CV-EX system bringing the maximum total system capability up to 120
units. The versatile CV-EX system provides one central location to monitor and program
the controllers instead of having to program individual thermostats. The system has many
features typically not found with programmable thermostats such as: central operators
interface, heating/cooling failure alarm, change filter alarm, full energy saving
economizer control, and holiday scheduling.
Below are a few of the typical applications the CV-EX system is commonly used for.
