Support & Manuals

FAQs

How does the EC motor improve energy efficiency?+

The VIVOSUN AeroZesh S4 uses an Electronically Commutated (EC) motor with PWM control, which is far more efficient than traditional AC motors. This technology can reduce power consumption by up to 50%, saving you money on electricity while providing precise speed control from 0-100%. EC motors also run cooler and have a longer lifespan.

What size growing space is this system designed for?+

This 4-inch, 208 CFM system is ideal for small to medium growing spaces, such as a 2'x2' grow tent up to a 4'x4' grow tent. Its mixed-flow design ensures effective air exchange even with ducting runs up to 8 feet, making it a versatile choice for various setups.

How do I set up automated responses with the GrowHub controller?+

Programming is done through the VIVOSUN mobile app, which connects to the GrowHub E42A via WiFi. You can create custom automation rules, such as increasing fan speed when temperatures exceed a set threshold or activating the fan when humidity rises. For more detailed guidance, consult our grow room climate control guide.

Can I connect multiple VIVOSUN devices to one controller?+

Yes, the GrowHub E42A platform is designed to unify multiple compatible VIVOSUN smart devices, including products like the AeroLight A100 LED grow light. This creates a fully integrated automation ecosystem where all your equipment works together seamlessly.

What maintenance does this filtration system require?+

Maintenance is minimal. We recommend cleaning the fan blades monthly and replacing the carbon filter every 12-18 months, depending on usage. The controller's sensors should be gently wiped with a dry cloth quarterly to ensure accurate readings. The EC motor itself is virtually maintenance-free.

What happens if my WiFi connection is lost?+

The system will continue to operate based on the last settings you programmed. The GrowHub controller stores all automation rules locally, ensuring your environment remains stable even without an active internet connection. Once WiFi is restored, the system reconnects automatically.
