Initial Setup

Before applying power to control, confirm Modbus
addresses of the fans. (If used in a networked
application.)
1. Apply power to the HVLS control. The control
will display "Initializing Control" and "Setting up
Firmware".
2. Once the control initializes, it will begin searching
for fans. The control will display its searching
progress at the bottom of the screen.
3. Once fan searching is complete, the control will
indicate the number of fans discovered on the
network. If the correct number of fans is found, tap
the "Next" button. Otherwise, verify all electrical
and shielded CAT-5e connections to HVLS fans
and tap the "Retry" button to search for fans again.
4. After the number of fans is confirmed, the control
will ask the user if a passcode is desired. To set up
a passcode, tap the yes button, type a four digit
passcode on the pop-up keyboard, and tap save.
To skip this step, tap the no button.
5. The subsequent screen will show each of the fans
discovered. Each fan will have a Modbus address,
followed by a default name.
