Our fan drives communicate using Modbus, which is difficult to set up and use for complex wireless networks. However, having each fan on its own breaker allows for easier troubleshooting if any issues arise. This is a decision that the installing electrician will need to make based on the amp draws we provide in our installation manual and specification sheets.Ĭan I install more than 1 fan on my breaker?Īssuming the breaker is sized correctly for more than one fan, and all national and local codes are adhered to, it is acceptable.

There are many factors that go into sizing a breaker that MacroAir cannot account for. What size breaker should I use for your fans? This prevents comparison of legitimate CFM numbers to numbers that are obtained from dishonest or outdated calculation methods. What are your fans’ CFMs? When will numbers be published?ĬFM Numbers will not be available until a regulatory body mandates that every HVLS fan manufacturer adheres to the same standards of calculating CFM. Two leads need to be swapped on the OUTPUT side of the drive in order to reverse rotation you cannot swap two leads of the incoming power. Why is my fan spinning backwards (clockwise) when the remote is set to forward? No you will need either a Controller 30 or Controller 4 to control more than one fan from the same interface. You will need a new control panel in the correct voltage.Ĭan the standard touchpad remote run more than one fan? Can I change the parameters?Ĭhanges between voltages are hardware changes and have nothing to do with parameters. I ordered my fan for 240V 3PH, but I need a different voltage now. If you read the control panel, you will notice that it is set up for single phase input, but outputs 3 phase power to the motor. I ordered 240/1PH but received a 3PH motor. If a different size is needed, a different gearbox is needed. No the AirVolution and AirLegacy line sizes are determined by the gearbox ratio rather than VFD programming. I ordered a 14' AirVolution, but actually needed a 16'. You cannot use 20’ or 24’ blades on a motor meant for 14’-18’, or vice versa. They may look similar, but the motor for the 20’ and 24’ has increased torque needed to drive the larger blade sizes.

The power units look the same does it matter which one gets which blades? I ordered a 14’ X Series and a 20’ X Series. Please contact Technical Support for assistance. If this change is being made after installation, the fan will need to be I ordered a 14’ X Series, but actually needed a 16’. What is the maximum length of remote cable/CAT5?Ĭontroller 4: 200 ft. The X Series uses a different motor and VFD configuration that allows for longer cable lengths. Why is the motor cable 25 ft on AirVolution/AirLegacy Series but 50 ft on an X Series? In order to maintain the warranty of the fan, the length increase must be approved by MacroAir in writing BEFORE placing a fan order. Longer lengths may be approved depending on the application. Can I install a motor cable longer than the standard provided length?
