About this task

Note: This procedure is for the ZEC310 zone dampers and it is the minimal configuration needed for temperature and flow control. See the ZEC310 table in Appendix B: Objects and parameters

Complete the following steps to check the zone damper:

Procedure

  1. Log on to the SBH200.
  2. From the device list, select the COBP zone you want to configure.
  3. Navigate to the zone home page to see an overview of the status of the unit.
  4. Check that the Zone Temperature reads properly.
  5. Check that the Warmer Cooler Adjustment works properly.
  6. Navigate to the Equipment Setup tab.
  7. Check which direction closes the dampers and use the Damper Polarity parameter to set that position.
  8. Set the Actuator Stroke Time to 60 seconds.
  9. Select the Commissioning tab to set the flow, DCV, and Title 24 Load Shed.
    Note: If you cannot see the DCV tab, set the DCV Enable parameter to CO2 for it to appear.
  10. Look under the Flow section to set damper positions.
    1. Set the minimum positions settings for heating or cooling to 0% and 100% to drive the damper open and closed. Select heating or cooling based on the current state of the box.
      Note: If the damper does not open or close, remove power from the ZEC310, press and hold the red manual release button on the actuator, and check that it can move freely. This button unlocks the actuator so you can manually move it. Reconnect the actuator so it moves freely. Ensure the direction to close is the same as what you set earlier in this procedure.
    2. When the actuator works properly, set the minimum and maximum damper positions for each zone. This helps to balance the system flows.
  11. Select the Control Setup tab and check that each parameter is set to customize the zone to the user's needs. For example, check if a warmer or cooler adjustment is needed, if you need temporary occupancy, or set the zone weight and the zone’s voting options. Use the Trends tab to diagnose issues and see the history of the zone temperature.
