ZEC510 VAV Controllers
Installation Instructions
LC-ZEC510-x
Applications
The ZEC510 VAV controller is a component of the Verasys® SMART Equipment™ family. The ZEC510 variable air
volume (VAV) controller runs a pre-engineered HVAC zoning sequence and provides the inputs and outputs you
require for VAV applications.
The ZEC510 controller has an optional occupancy feature that makes it possible for the controller to switch from
occupied mode to standby mode based on zone activity. Standby mode maximizes energy savings by using
setpoints that are higher and lower than occupied mode setpoints.
The ZEC510 controller uses plug and play technology to detect which network sensor types are connected. See
the Operation section to determine the availability of additional sensor product information.
Use the Verasys Smart Building Hub (SBH) to configure the ZEC510 controller. Use the SBH or the VAV Balancing
Thermostat to commission the controller.
IMPORTANT: Use this ZEC510 VAV controller only as an operating control. Where failure or malfunction of the
ZEC510 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 ZEC510 VAV controller.
IMPORTANT: Utiliser ce ZEC510 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 ZEC510 VAV controller.
