Frequently Asked Questions
What is AirEffect?
AirEffect is an optional program for the Controller 10/20/30 that utilizes temperature and humidity sensors to determine the optimal speed and direction to runs the fans and makes changes automatically, requiring no input after it is set up.
Is AirEffect available for the standard touchpad?
No.
Is AirEffect available for the controller 4?
No, although a temperature sensor option is available for the Controller 4. This option is far simpler than AirEffect and turns the fans on and off at a set point, rather than adjusting direction and speed.
Can I use AirEffect with my BMS?
No, AirEffect is only available for the Controller 10/20/30.
If I order a network without AirEffect, or if my fans are on standard remotes, can I add AirEffect later?
Most networks can be upgraded to AirEffect with programming, hardware, and wiring additions and changes. Installs using standard remotes will need to upgrade to a Controller 10/20/30. Give us a call at 866-668-3247 to discuss upgrading a network.
What is a zone?
A zone is a specified area to run AirEffect in. In practice, a zone is typically a single room. If there are fans in multiple rooms, multiple zones will need to be set up. Each zone will need its own pair of sensors. We recommend contacting MacroAir to determine the best zone layout for your application.
What is the maximum number of zones AirEffect supports?
AirEffect supports up to 4 zones per controller. If you require more zones, you will need to purchase multiple controllers with AirEffect.
Can I use remotes to control my fans individually along with the network controller?
No, the fans can only accept inputs from one source.
Do I need repeaters?
Repeaters are required for every 5 AVD fans. If you are using 4 fans or less, you do not need a repeater.
How many repeaters do I need?
Repeaters are needed for every 5 AVD fans. If you have 10 fans, you need two repeaters.
If I order a Controller 10, but add more fans later and wish to upgrade to a Controller 20, is that possible?
Yes, MacroAir offers upgrade options for existing controllers. Speak to your MacroAir sales representative to learn more.
Is there any way to control more than 30 fans from a single controller?
Unfortunately, 30 fans is the limit. If you need to control more than 30 fans, you will need to purchase more than one network controller.
Is there a maximum length of cable I can run between fans?
The maximum length of CAT5 cable from the screen to the last fan is 4000 feet, so as long as that requirement is met, the distance between fans does not matter.
Can an external start/stop switch be integrated into my controller?
Certain fans do allow for a separate on/off switch to be integrated. Please contact your sales representative for more details.
Can I use AirEffect with my Controller 4?
No, AirEffect is only available for the controller 10/20/30. However, the Controller 4 does have a temperature sensor option, where the fan will turn on and off around a set temperature point at the speed and direction programmed. It will not automatically adjust speed and direction like “true” AirEffect.
Do I need repeaters with the Controller 4?
No, repeaters are only required on networks of 5 or more fans.
Can I use remotes to control my fans individually along with my BMS?
No, the fans can only accept inputs from one source.
Do I need an AirLynk for a Modbus RS485 BMS?
No, the fans speak Modbus natively and no additional equipment is needed to tie them into your BMS. AirLynks are only necessary and available for Bacnet and Lonworks systems.
How many fans can be on a single AirLynk?
AirLynk can control up to 8 AVD fans. If you wish to add more fans to your BMS, multiple AirLynks will be necessary.
Do I need repeaters?
Repeaters are required for every 5 AVD fans. If you are using 4 fans or less, you do not need a repeater.
How many repeaters do I need?
Repeaters are needed for every 5 AVD fans. As AirLynks can control up to 8 AVD fans, you will need a maximum of one repeater per AirLynk.
Can an external start/stop switch be integrated into my BMS?
Certain fans do allow for a separate on/off switch to be integrated. Please contact your sales representative for more details.
What is a drop length?
The drop length is defined as the distance between the building mounting point and the blades.
What is an extension length?
The extension length is the length of the actual extension tube itself. This differs from the drop length in that the drop length includes the extension length, mount height, and motor height. For example, a standard 550 drop length of 3’ utilizes a 1’10” extension length.
How do I order the appropriate length?
Tell your sales representative the total drop length from the ceiling to the blades that you need; they will be able to provide you the appropriate extension.
Can extensions be modified in the field?
Modifying extensions in the field is possible but not recommended, as they will no longer be under warranty should they fail. MacroAir highly recommends verifying the length needed before ordering. You also cannot modify the extension so that the drop length is below our recommended minimums.
Can I mount my AVD fan without a drop length?
No, the motor cannot be mounted directly to the mount.
What are the standard drop lengths?
AVD 370: 2 feet
AVD3 430: 3 feet
AVD3 450: 3 feet
AVD 550: 3 feet
AVD 780: 3 feet 2 inches
What are the minimum drop lengths?
AVD 370: 1 feet
AVD3 430: 2 feet
AVD3 450: 2 feet
AVD 550: 2 feet
AVD 780: 3 feet 2 inches
What are the maximum drop lengths?
Typically, MacroAir does not make extensions for drops over 10 feet. However, there are options available for longer drops. If you require a drop over 10 feet, please contact your sales representative to discuss options.
Where can I find pricing?
Contact us to locate the closest distributor to you.
How long will it take to get my fans?
Lead time on standard AVD fan orders is 10 business days. Custom orders may require a longer lead time. Contact your sales representative to learn more.
I ordered my fans for low voltage, but required high voltage. Is there any programming I can modify?
No, voltage changes require hardware changes and in most cases an entire new motor unit. Contact your sales representative if you require assistance.
Is there any way to upgrade the size of my fans after they have been ordered?
Certain models of fans allow for longer blades to be installed with some programming changes. Contact your sales representative to learn more.
Can I switch the remote style after ordering my AVD (ex. Digital to analog)?
Most fans can easily switch between different types of control. Please contact us with your specific application to learn more.
Where can I find the powder coating color options?
