Monitor The Health Of Your HVAC Units With Air Flow Sensors

How do you know if your HVAC System is operating at its best? Unless you are properly monitoring your system, you won't know there's a problem until you have a failure.

Follow these 3 easy steps to optimize your monitoring efforts and get the most out of your HVAC System.

The temp sensors monitor the temperature of the air going in and out, while the air flow sensor monitors the rate at which the air is coming out.

Step 1: Monitor Temperature with a smart Temperature Sensor

Your HVAC unit is essential to keeping your server room cool for your equipment. Without it, temperatures in your remote sites, server rooms, or equipment closets will rise quickly. Some high-capacity rooms can even hit 170 F or hotter. This can obviously fry your expensive gear.

The D-Wire Temperature sensor from DPS Telecom is an easy-to-use, smart sensor that interfaces with your RTU. The D-Wire temperature sensor will alert your RTU when the temperature is outside of your preset range. This saves you time, money, and headaches.

Step 2: Don't forget to monitor Air Flow.

While temperature sensors are necessary, they don't tell you the whole story. HVAC filters clog over time. Your temperatures will be maintained, but your HVAC will have to push itself harder and harder - increasing run time and reducing the unit's overall lifespan. Eventually, it won't be able to keep up at all. Temperatures will rise. You could even suffer thermal shutdowns and equipment damage that take service offline.

You could change all your filters on a schedule to mitigate this problem. But that's not very precise - you'll be too early with some changes and too late with others.

By using an air flow monitor, you can be the first to know the instant your equipment is at risk of an outage. All it takes is a well placed air flow sensor in your server room or data center to be sure that air is being properly circulated. If you're not using an air flow monitor, how do you know when your filter is clogged? You don't want an angry phone call from a customer (or your boss) to be the way you find out that there's a problem.

What you need is the D-Wire Airflow sensor from DPS Telecom. When placed in front of a vent, this sensor measures the rate at which air is being pushed out of your HVAC unit. A decrease in this rate indicates that your filters need to be replaced. It can also alert you to any other flow problem with your HVAC unit before your network goes down.

With a Plug 'n' Play design, D-Wire sensors are easy to plug into your DPS RTU. They can also be daisy-chained to other D-Wire sensors - occupying only 1 port for every 16 sensors. Once connected to your RTU, it's easy to configure your sesnors using the built-in web interface. The RTU will read the sensors automatically. All that's left to do is give them a name and set your thresholds.

Step 3: Complete your HVAC automation with an HVAC Controller:

The HVAC Controller G3 is specifically designed to monitor and control your HVAC unit(s). The RTU can manage lead/lag operations (up to 6 HVAC units) and has a testing feature that allows you to test the efficiency and health of each of your HVAC units. It is simple to install, easy to use, and can support D-Wire sensors.
