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 

Accessories

 for additional sensor 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.

Installation

Follow these guidelines when you install a ZEC510 controller:

• Transport the ZEC510 controller in the original container to minimize vibration and shock

damage.

• Do not drop the ZEC510 controller or subject it to physical shock.

Parts included

• One ZEC510 VAV Controller with removable system and zone buses, and power terminal blocks
• One self-drilling No. 10 mm x 25 mm (1 in.) screw

Materials and special tools needed

• 6 mm (1/4 in.) female spade terminals for input and output wiring and crimping tool or spade

mounted terminal blocks

• A small straight-blade screwdriver for securing wires in the terminal blocks
• An 8 mm (5/16 in.) wrench or a 10 mm (3/8 in.) 12-point socket to tighten the square coupler

bolt

• Shims or washers to mount the ZEC510 if necessary
• A power screwdriver
