The CV series equipment controllers, which include the CVM and CVE models, are designed for variable air volume (VAV) box applications. These controllers are fully programmable, but also feature a set of preloaded applications allowing these controllers to be made fully operational by selecting the appropriate VAV box application using the Mobile Access Portal (MAP) Gateway.
CV series controllers feature an integral damper actuator, and a digital Differential Pressure Transducer (DPT) sensor. Certain models also feature an integral potentiometer to sense actual VAV box damper position. CV series controllers include an integral real-time clock, which enables the controllers to monitor and control schedules, calendars, and trends, and operate for extended periods of time as stand-alone controllers when offline from the Facility Explorer system network. These controllers also connect easily to the wired and wireless network sensors for zone and discharge air temperature sensing.
CVE controllers communicate using the BACnet® Secure Connect (BACnet/SC) or BACnet/IP communication protocols. CVM controllers are switchable to use either the BACnet MS/TP or N2 communications protocol. Equipment controllers in BACnet/SC, BACnet/IP, or BACnet MS/TP communication mode are BACnet network-compliant devices. You can use controllers running in N2 mode to maintain or modernize sites with installed legacy Johnson Controls® controllers.
