Mounting and wiring - Verasys - LIT-12012371 - LC-SBH200-0 - Building automation software - Verasys System - 4.2

1. Install the SBH200 in a location that is easy to access. Install power wiring but do not apply power.
2. Install the zone coordinator in a location that is easy to access. Install power wiring but do not apply power.
3. Devices on the system bus must start at 5 and work up sequentially in unbroken order to a maximum of 105. For example, set the address on the first zone coordinator to 5, the next to 6 and so on. Do not skip or duplicate addresses on the system bus.
   Note: A maximum of 10 VZC100's or 100 devices are allowed on the system bus. There is a maximum of 20,000 points in any case.
4. Use 22-3 shielded cable to connect the blue four screw terminal system bus plug on the SBH200 to the blue four screw terminal J12 system bus port located on the VZC100 addressed 6. From the system bus plug on VZC100 address 6, run another cable to the system bus plug on the next device addressed 7 and repeat for following sequential addresses, this forms a daisy chain wiring configuration.
5. The end of line (EOL) termination switch must be switched to the on position on the devices located at the start and end of the system bus. All other devices must be switched off.
   Note: The VZC100 has three EOL switches located on it. Use the switch labeled BAS EOL located beside the terminal J12 bus port for the system bus.
6. Each zone coordinator zone bus must serve the RTU, BYP200 and zone dampers or VAVs served by the RTU. The steps below outline the procedure for a VZC100 that controls the RTU that in turn serves a group of zone dampers or VAVs, where the VZC100 uses address 5, RTU controller uses address 5, BYP200 uses address 6 and ZECs use addresses 7-8.
7. Install the SSE RTU with Comm1001 communications card or the VEC100 generic RTU controller. Install power wiring but do not apply power at this time.
8. Install the BYP200 on the bypass damper and secure the locking collar to the damper shaft. Take note of the damper direction to close. Do not apply power to the BYP200 at this time.
9. Remove power and press the manual override button on the BYP200. Manually rotate the dampers to the fully closed position.
10. Install the ZEC310 on the zone damper or the ZEC510 on the VAV box and secure the locking collar to the damper shaft. Take note of the damper direction to close. Do not apply power to the ZEC310/510 at this time.
11. Remove power and press the Manual Override button on the ZEC310/510. Manually rotate the dampers to fully open position.
12. Devices on the zone bus must start at 5 and progress in sequence, one-by-one, up to a maximum of 32. Set the address on the RTU controller to 5. The address for the next ZEC is 6, and so on, up to a maximum of 32 on the zone bus. Devices must be added in sequence, one-by-one, to the zone bus. Do not skip or duplicate addresses on an individual zone bus.
13. Use 22-3 shielded cable to connect the gray or brown zone bus plug J11 on the zone coordinator to the FC bus on the Comm1001 or the zone bus of the VEC100. From the FC bus or zone bus of the RTU controller that has address 5, run another cable to the zone bus plug on the BYP200 that has address 6. Repeat the procedure from the zone bus of BYP200 that has 7 to the zone bus on ZEC that has 8, and so on in a daisy chain configuration.
14. The EOL switch must be switched to the on position for devices located at the beginning and end of the zone bus. All other devices must be turned off.
    Note: The VZC has 3 EOL switches located on it. For the zone bus, use the switch labeled CS EOL located beside the terminal J11 zone bus plug.
15. Connect power to the SBH200.
16. Log on to the SBH200.
17. Connect power to the RTU controller.
18. Navigate to the Devices page in the Verasys user interface. The VZC100 address 5 appears after a few minutes in the Devices menu and the circular spin icon changes to a black arrow.
19. Connect power to the RTU controller that is connected to the zone bus of the VZC100. For a RTU controller unit that is new out of the box, the unit populates under the VZC100 as address 4. Wait for the circular spin icon to change to a black arrow.
20. Click on the RTU in the Devices list. Navigate to Controller > Network > Device Address. Click on the Device Address value box and set the address to 5. Click Save.
21. Click on the Devices tab on the left menu to display the devices page.
22. The RTU controller address 5 should populate in the list. Device address 4 grays out and appears offline.
23. Wait for the circular spin icon on the right hand side of the RTU controller address 5 to change to a black arrow. Click on the Remove Offline Devices at the bottom of the page. The grayed out offline RTU controller address 4 dissapears from the devices list after a few minutes.
24. To set up the RTU follow either of the links below for your RTU controller type:
    • If the RTU is a SMART Equipment device, see Configuring a Smart Equipment unit for COBP control using the SBH.
    • If a VEC controls the RTU, see Configuring a VEC for COBP using the SBH.
25. Apply power to the BYP200. The unit populates under the RTU as address 6.
26. Adjust the duct static pressure set point on the BYP200 or the RTU controller.
27. Use the unit to supply the air to the space, navigate to the Zone Coordinator and set the Construction Mode to deliver Heat or Cool.
28. Use the following sections to check your configuration:
    • For ZEC310 configuration: Configuring a COBP zone damper (ZEC310) for temperature and flow control
    • For ZEC510 configuration: Checking the VAV box
29. When all of the ZEC's and BYP200 are connected to the zone bus, are online in Verasys, and are configured correctly according to Checking the zone damper set the construction mode to not in use.
30. Set up a schedule to control the RTU.
