AutoVent FanChief Commercial wireless fan controller with a touch screen display for variable-frequency-drive control of AmeriWind HVLS fans

System overview

The FanChief Commercial is designed for easy installation and operation. The system is designed to control variable frequency drives on AmeriWind fans.

This is Section 1, the electrician’s guide for the FanChief system. The system is designed for the unique challenges of HVLS fans.

Main features

The FanChief system provides:

  • Automatic control of VFD by time
  • Touch screen display
  • Up to 9 fans, each with their own speed
  • 0–10v output for analog controlled fans
  • Modbus output for wireless fans

Installing the FanChief

Consider the following before installing the FanChief:

  • Protect the enclosure from moisture – mount it in a secure and dry place.
  • Important: only drill holes in the bottom of the enclosures.
  • Condensation runs downhill. Drilling holes into the top or upper sides of the enclosure voids the warranty.

Extending the temperature sensor

  1. Run 18–22 AWG wire (twisted or shielded wire if possible) from the sensor to the FanChief. Keep the sensor wire away from high voltage wire by at least 24 inches / .5 meters. Specifically, keep it away from the VFD output wires.
  2. Solder or use gel-filled crimps to connect your wires to the temperature sensor.

Wired Modbus FanChief power

The wired Modbus FanChief gets its power from the VFD. At least 1 of the VFDs will need to be powered up. No external power is needed. It should turn on as soon as a VFD has power.

How many fans should I have connected?

In the FanChief’s setup menu, P5 (number of fans) needs to be set to the fan quantity connected to the system. Then make sure each fan’s VFD Modbus address is unique. See below.

Fan’s Modbus addresses

  • Fan #1 with an Invertek brand VFD needs to have a Modbus address of 21.
  • Fan #2 with an Invertek brand VFD needs to have a Modbus address of 22.
  • Fan #3 with an Invertek brand VFD needs to have a Modbus address of 23.
  • Fan #4 with an Invertek brand VFD needs to have a Modbus address of 24, and so on.

Home screen & all-fans control

This is Section 2, programming. The home screen controls all fans. It has a main off/on for all fans, and a blank space that takes you to the menu.

If the All Fans Off button is selected, no fans will run and the timers are deactivated. If the All Fans On button is selected, only the enabled fans will run. The timers will be able to enable or disable individual fans.

Time clock for fans

The time parameters allow you to start and stop the fan via a weekly time clock. On the time clock screen you set the day of week the timer applies to, when fans turn on, when fans turn off, and which fans are affected. Press any blank space to exit.

The applicable days and fans applied are selectable. Any combination of fans can start or stop automatically.

If you simply want to make sure all the fans get turned off at the end of the shift, select all the fans and set an Off time for shortly after the shift ends.

Hours are on a 24 hr basis; 0:00 means disabled. There are up to 20 time periods. If there are 9 or more fans, 9 and above will mimic fan 8’s time parameters.

Individual fan page

Each fan has an individual screen with independent speed and direction. The individual fan page shows the selected fan, whether the fan is enabled, the fan’s direction, and the fan’s speed. Change the selected fan by pressing another fan in the bottom row. Press any blank space to exit.

From this area you can also reach the time clock, fan motor data, change date, and change time.

Parameter reference

There are several parameters that you can change. The parameters are labeled P1, P2, and so on. These parameters are the temperature setpoints and values you can adjust. From the menu you can scroll to other parameters and edit each parameter ID.

Fan Hz

The fan Hz scales each fan’s 0–100 percentage to the actual motor hertz or speed. Normally this is preset before the controller is delivered. Don’t think you can run them at unlimited speeds. The actual usable max speed is limited by the fan itself. You can also invert a fan’s rotation with P201 through P219.
