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... -
Page 6: Mounting
• Ensure that the mounting surface can support the ZEC510 and any user-supplied enclosure. • Mount the ZEC510 on a hard, even surface. • Use shims or washers to mount the ZEC510 securely and evenly on the mounting surface if necessary. - Page 7 Place the ZEC510 on the actuator shaft so that the wiring connections are easily accessible. Ensure that the ZEC510 base is parallel to the VAV box, perpendicular to the damper shaft. If necessary, use a spacer to offset tipping of the ZEC510 caused by the shaft bushings.
- Page 8 For 45° and 60° boxes, you must provide hard stops at both full-closed and full-open damper positions. If you install the ZEC510 at the full-open position, it provides the open stop for 45° and 60° boxes. The closed damper seal provides the full-closed stop.

The sensor bus terminal block is a brown, removable, 4-terminal plug that fits only into the brown, board-mounted sensor bus jack. Wire the removable sensor bus terminal block plugs on the ZEC510 and other field devices in a daisy-chain configuration using 4-wire twisted, shielded cable as shown in Figure 3 and Figure 4. -
Page 11: Modular Ports
VZC100. Modular ports The modular sensor and zone bus ports on the front of the ZEC510 are RJ12, six-position, modular jacks. The modular sensor bus ports provide a connection for the VAV Balancing Tool. The zone bus port is not used in ZEC510 installations. The following figure shows the pin number assignments on the modular port. -

Page 24: Sequence Of Operation
Note: • One exception to the above staging procedure is if the ZEC510 controls hot water valves and the Control Application Type is set to Incremental. The system assumes that there is an incremental water valve and you can set Dual Max Enable to Enable. This option can provide tighter control of air exiting the box. -

Page 26: Setup And Adjustments
Setup and adjustments Setting the ZEC510 device address Before you apply power or operate the ZEC510, you must set a valid and unique device address for the controller on the bus. Ensure that your system meets the following prerequisite configuration and complete the addressing steps. -
Page 27: Accessories
The controllers do not need to be physically connected on the bus in their numerical device address order. Note: The ZEC510 uses a single 8-way DIP switch to set the address. The switch is binary weighted, so you can set addresses from 4 to 127. The DIP switch block has eight switches numbered 128, 64, 32, 16, 8, 4, 2, and 1. -
