About this task
This method uses the SBH connected to a zone coordinator. To configure a VAV controller for a VAV system, complete the following steps:
Procedure
- Log on to the SBH200.
- From the Device list, select the VAV zone you want to configure.
- On the zone home page, you can see an overview of the unit status.
- Check that the Zone Temperature appears properly.
- Check that the Warmer Cooler Adjustment works correctly.
- Navigate to the Control Setup tab and ensure that Control Application Type has the correct setting. When you change this parameter, the controller restarts and you lose all other parameter settings.
- Navigate to the Equipment Setup tab.
- Turn the blade extension shafts a certain direction to open the dampers mechanically.
- Check which direction closes the dampers and use the Damper Polarity parameter to set that position.
- Set the Actuator Stroke Time to 60 seconds.
- If the VAV box has heating functionality, set the parameters for the heating.
- If the VAV box has a fan, set the parameters for the fan type.
- If you want to calibrate the temperature, adjust the ZNT sensor offset so the temperature matches the sensor that you calibrate to.
