Make Your HVAC System Work Smarter, Not Harder

The number one function of an HVAC system is to provide thermal comfort for occupants in a given space. The system design also has to adhere to building codes. One of those codes is to deliver the proper amount of Outdoor Air. If you have an HVAC system without an accurate OA sensor, how do you know how much OA is coming into the space?

Think of it like driving a car without a speedometer. Sure, the car runs—but you have no idea how fast you’re going. The same applies to your

GreenTrol Helps You Take Control

The operation of the HVAC system is an integral part of any building design. The system needs to work properly and efficiently. All commercial buildings require a certain amount of Outdoor Air. Many products go into making the HVAC system operable and efficient. The best way to properly bring in the correct amount of air is to install an accurate OA sensor and integrated controls. When that is correctly done, the HVAC system works properly and more efficiently.
