ZEC410 VAV Controllers
Installation Instructions
LC-ZEC410-xx
Applications
The ZEC410 VAV Controllers are components of the Verasys SMART equipment family. The VAV Zone controllers run
a pre-engineered HVAC zoning sequence and provide the inputs and outputs required for this application.
The ZEC Controller contains multiple features to ensure occupant comfort. Optional occupancy sensing capability
enables the ZEC controller to switch from occupied mode to standby mode based upon zone activity. Standby mode
maximizes energy savings by using setpoints that are higher and lower than occupied mode setpoints.
The ZEC410 controller also uses plug and play technology to detect which network sensor types are connected. See
the Accessories section to determine availability of additional sensing product information.
You use the Verasys Smart Building Hub to set up the ZEC410 controller. The VAV controller commissioning is
performed with either the Smart Building Hub or the VAV Balancing Thermostat.
IMPORTANT: Use this ZEC410 VAV controller only as an operating control. Where failure or malfunction of the
PEAK OEM controller could lead to personal injury or property damage to the controlled equipment or other
property, additional precautions must be designed into the control system. Incorporate and maintain other
devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against
failure or malfunction of the ZEC410 VAV controller.
IMPORTANT : Utiliser ce ZEC410 VAV Controller uniquement en tant que dispositif de contrôle de
fonctionnement. Lorsqu'une défaillance ou un dysfonctionnement du controller risque de provoquer des
blessures ou d'endommager l'équipement contrôlé ou un autre équipement, la conception du système de
contrôle doit intégrer des dispositifs de protection supplémentaires. Veiller dans ce cas à intégrer de façon
permanente d'autres dispositifs, tels que des systèmes de supervision ou d'alarme, ou des dispositifs de
sécurité ou de limitation, ayant une fonction d'avertissement ou de protection en cas de défaillance ou de
dysfonctionnement du ZEC410 VAV controller.
