You can place the system into balancing mode through the Commissioning section of the zone coordinator on the SBH. When the balancing mode starts, the zone dampers fully open and the bypass damper is closed. The supply fan continues to run regardless of occupancy and any heating or cooling is turned off.
When balancing mode is turned off, the system returns the bypass damper to static pressure control. The zone dampers are released to operate and RTU heating and cooling are released to operate as required.
Note: The system
automatically returns to normal operation if balancing mode is left to operate for 8
hours. This automatic expiration safeguards the system from constantly running with
dampers fully open in the event the user forgets to disable balancing mode.
