The following section provides a high level overview of the steps involved to
start a Verasys VAV system. Refer to your device installation instructions
for specific wiring and installation details. If you use a wireless system
with TMR100, refer to the Verasys TMR Series Wireless Router
Installation Guide (LIT-12014167). The steps below also apply
for a TMR wireless system. If you plan a TMR wireless system each device
requires a TMR to be connected with 22-3 awg shielded cable to the system
bus or zone bus, instead of daisy chain wiring to each device. The TMR100's
form a wireless communication network that replaces a hardwired network. To
keep the space temperature under control during installation, complete the
following steps:
Note: Wireless NS8000 sensors can only
be used with WRZ7860 connected to the sensor bus of a controller.
Refer to WRZ Series One-to-One Wireless Room Sensing System
Technical Bulletin (LIT-12011641).
- Install the SBH200 in a location that is easy to access and install power wiring but do not apply power.
- Install the zone coordinator in a location that is easy to access and install power wiring but do not apply power.
- Devices on the system bus must start at 5 and progress sequentially, one by one,
up 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 VZC's or 100 devices are allowed on the system bus. There is a maximum of 20,000 points in any case.
- Use 22-3 awg 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.
- 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. For the system bus, use the switch labeled BAS EOL located beside the terminal J12 bus port.
- Each zone coordinator zone bus must serve both the RTU and VAV being served by the RTU. The steps below outline the procedure for a VZC100 that controls the RTU that serves a group of VAVs, where the VZC100 uses address 5, RTU controller uses address 5 and ZEC use addresses 6-8.
- 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.
- Install 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 ZEC510 at this time.
- Remove power and press the manual override button on the ZEC510. Manually rotate the dampers to the fully open position.
- Devices on the zone bus must start at 5 and progress sequentially, 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, followed by 7 and so on up to a maximum of 32 on the zone bus. Devices must be added one by one, in sequence, to the zone bus. Do not skip or duplicate addresses on an individual zone bus.
- Use 22-3 awg 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 addressed 5, run another cable to the zone bus plug on the next device addressed 7 and so on to form a daisy chain.
- 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 switched 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.
- Connect power to the SBH200.
- Log on to the SBH200.
- Connect power to the RTU controller.
- 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.
- 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.
- 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.
- Click on the Devices tab on the left menu to display the devices page. The RTU controller address 5 should populate in the list. Device address 4 grays out and appears offline.
- Wait for the circular spin icon on the right hand side of the RTU controller address 5 to change to a black arrow and click on the Remove Offline Devices at the bottom of the page. The grayed out offline RTU controller address 4 dissappears from the devices list after a few minutes
- Turn on the RTU. Ensure it connects to the zone coordinator. See the following
sections and complete the relevant steps before proceeding.To set up
the RTU follow either of the links below for your RTU controller
type:
- If the RTU is a Smart Equipment unit, see Configuring a Smart Equipment unit for VAV system using the SBH .
- If it is a Verasys Equipment Controller, see Configuring a VEC using the SBH .
- You can now use the RTU to supply the air to the space. To do this, do not apply power to the VAV box controller and use the red manual override button to open up the damper and adjust the supply air setpoint on the RTU.
- When you are ready to set up the ZEC510 VAV controller served by the RTU mentioned in the last step, where possible, apply power to the controllers one at a time. They populate in the devices list under the zone coordinator.
- Use the following sections to check your configuration:
- Configure the schedule. See Verasys schedules.
