Note 1:
These objects are only valid when operating in Fume Hood Mode (MSI2=4).
Note 2:
This object is only valid when operating in Setpoint Mode (MSI2=1)
Note 3
: This object is NOT valid when operating in either Fume Hood Mode (MSI2=4) or Hibernate Mode (MSI2=5)
Note 4:
This object is only valid when operating in BACnet Mode (MSI2=3)
Note 5
: Save active configuration to Nonvolatile Flash memory. Please review section 7.1.1 for further information.
Writing a value of one (1) to the BACnet Object BV2 will cause the controller to copy the active
configuration stored in volatile (RAM) memory and write it to nonvolatile Flash memory. Nonvolatile Flash
memory has a limited number of Lifetime Write Cycles. Use this feature only when necessary.
Note 6
: This object is only valid when operating in Setpoint Mode where physical input AI1 is controlling Setpoint
The AVC control module includes a USB port which provides local connectivity for
programing the AVC using the PC based software tool “Insight” described in Section 6.
For BACnet operation, the PC must be disconnected from the local USB port to avoid
conflicts.
