Greenheck HVLS User Manual

HVLS Touchscreen Control 9
®
The following communication point lists apply to touchscreen control installations that were provided with optional
BACnet MSTP communication for building management system (BMS) integration. BACnet points must be
programmed into the building’s BMS (by others) for proper communication between BMS and the touchscreen
control.
NOTE: X denotes Modbus address values between 2-31 that are set via dipswitches on the fan’s variable frequency
drive circuit board.
