System Bypass: The system bypass mode allows some limited control of fans in the event of an HMI
failure or disconnect. Turning system bypass to ON will force all fans to their predefined BMS speed until
system bypass is turned back off. The system bypass will override the BMS, Auto, or Manual mode
operation.
Set Modbus Address: The Set Modbus Address value allows the user to set a specific network address
for the controller. This makes it possible for multiple controllers to be recognized on a single network.
Product Mode: Allows the user to set the software between HVLS or General Ventilation Fan
configurations.
DDC Mode: The DDC Mode menu allows the controller to receive commands from a Direct Digital Network
such as BACNET, Lonworks, or CASlink. These specific commands are outlined in the DDC section of this
manual. Examples of remote commands are controlling the on/off state of the fan and monitoring fan
operating conditions. When DDC is enabled, control of the fans from the HMI is disabled.
Scheduling: Scheduling allows for fan groups to follow a 7-Day occupied and unoccupied schedule. Each
day can have up to 2 occupied times. If scheduling is enabled, the scheduling menus become available on
the HMI. Scheduling works in AUTO mode only, and fans will operate based on temperature only during
scheduled times.
Rev. Activation (HVLS only): Allows the fan to automatically run in reverse when the temperature is
below the set reverse activation temperature range. The fan will not shut off until the temperature rises
above the set range (reverse temperature + reverse hysteresis).
Set System Time: Allows the user to set the current system date and time. Year, Month, Day, Hour,
Minute, and Seconds can be configured.
