Question 1

What is the Sentry Pac Pro™?

Accepted Answer

It’s a programmed aeration controller that automatically runs your grain bin fans at the best times based on outside temperature and humidity — proactively keeping grain in condition without constant monitoring.

Question 2

How does Sentry Pac Pro™ work?

Accepted Answer

The system senses outdoor conditions and turns fans on and off at precise times to reach your target grain temperature and moisture. It takes the guesswork out of managing aeration.

Question 3

What makes Sentry Pac Pro™ different from other aeration systems?

Accepted Answer

Most competitors react after grain is already out of condition. Sentry Pac Pro™ is proactive—it prevents spoilage before it starts by maintaining optimal conditions automatically.

Question 4

Do I still need to check my grain manually?

Accepted Answer

While it’s always good to physically check your grain, Sentry Pac Pro™ dramatically reduces the need to climb bins or rely on cables. You’ll know your grain is being protected 24/7.

Question 5

Can Sentry Pac Pro™ be added to my existing grain bins?

Accepted Answer

Yes. It’s designed to retrofit onto most existing fans and control boxes. Installation is straightforward, and we can guide you through setup.

Question 6

Do I need an electrician to install it?

Accepted Answer

We recommend using a qualified electrician to connect the controller safely and ensure your fans are wired correctly.

Question 7

Does it require Wi-Fi or internet?

Accepted Answer

The controller itself runs independently, but the app and connected features use cellular connection for remote access and alerts.

Question 8

How many bins can one controller manage?

Accepted Answer

You can control 1-100+ bins. Each unit manages one or multiple bins depending on your setup. Call us so we can get you set up for your specific needs. (308) 352-8624.

Question 9

Can it help reduce over-drying or moisture loss?

Accepted Answer

Yes. By running fans only when outside conditions are right, Sentry Pac Pro™ prevents over-aeration and helps preserve test weight and profit.

Question 10

How does Sentry Pac Pro™ handle re-wetting?

Accepted Answer

You can set a moisture target, and the system uses natural air at ideal conditions to gently re-wet your commodity—maximizing yield and quality.

Question 11

Can I control my fans from my phone?

Accepted Answer

Yes! The upcoming Sentry Pac Pro™ App lets you view bin conditions, turn fans on/off, and manage your bin remotely.

Question 12

Is there a subscription fee for the app?

Accepted Answer

The core app functions are included with your system. Optional add-on features like multi-site management and advanced data logs may have future upgrade options.

Question 13

What happens if the power goes out?

Accepted Answer

The system saves your settings and resumes your programmed schedule automatically when power returns. (As with any power failure, it's good practice to physically check any electrical equipment).

Question 14

Is there a warranty?

Accepted Answer

Yes. Sentry Pac Pro™ includes a standard manufacturer’s warranty against defects for a period of 5 years from date of purchase.

Question 15
