KVT-400 Ventilation Control
The programmable controller offers convenient automatic control of curtains, fans, soakers, and lights.
Stop choosing between fresh air and wet bedding.
Manual curtain management is a losing battle. If you’re seeing foggy air, damp bedding, or condensation on your stalls, your barn is under-ventilated—leading directly to winter respiratory issues.
The KVT-400 was designed exclusively for livestock. Unlike generic controllers, it “thinks” like a farmer: it uses advanced sensors to identify wind direction, closing only the windward curtains to block drafts while keeping the rest of the barn open for vital air exchange.
Smart Automation Features
Weather Intelligence
- True Rain Sensing: One sensor manages the whole barn, closing only the curtains facing the storm.
- Wind-Responsive: Automatically adjusts based on wind speed and direction to prevent "tunneling" drafts.
- Simplified Wiring: Includes built-in weather station wiring aids to get you up and running faster.
Livestock Comfort
- The "Sweet Spot": Programmed to keep Holsteins in their ideal 20° to 76°F range.
- Calf & Dairy Specific: Pre-set parameters that actually make sense for animal health, not just building temperature.
- Safety First: Constant curtain load monitoring prevents mechanical mishaps before they happen.
Remote Management
- Live Monitoring: View online temperature and movement graphs from your phone or truck.
- Remote Operation: Open or close curtains manually via the web if you're away from the barn.
- Reliable Connectivity: Choose between built-in Wi-Fi or an annual AT&T cellular service plan.

Why AutoVent?
AutoVent was founded by Kevin Hoover out of a simple necessity: Most controllers didn’t know how to handle wind.
While other systems blindly close every curtain when the temperature drops, the KVT-400 is built to be selective. By closing only the windward side, your barn maintains maximum air exchange at lower temperatures, keeping your herd dry and respiratory-risk-free.
