SCADA Supervisory Control and Data Acquisition - SCADA Gear in a large data center provides supervisory control and data acquisition (SCADA) to maintain electrical and mechanical equipment. SCADA System is used in many different industries for controls and security including DDC HVAC Controls. SCADA systems are an integration of PLC controls and offer an interface for technicians to monitor and control the equipment. SCADA can also be integrated with a DDC system and can offer remote monitoring over a network or internet. (more…)
Direct Digital Controls DDC or DDC Systems offer a high level of control for building mechanical and electrical systems. Additionally, the modern state-of-the-art direct digital controls have the ability to offers trends of data points of HVAC/Electrical equipment. Trending can be used to increase efficiency and troubleshoot problems with mechanical equipment. DDC integration can occur with any type of mechanical or electrical system in the building.
Additionally, the system can communicate via the internet for remote monitoring and control. Alternative names are building automation systems, building management systems, and energy management systems. (more…)
Duct Temperature Sensor - The duct static temperature sensor measures air temperature in the ductwork. The solid-state temperature sensing devices are commonly used in HVAC applications that are controlled by direct digital control or a modern building automation system. At the base of the box is a probe that sticks into the air stream of the ductwork. As the air passes over it, the probe changes resistance. (more…)

Alerton Controllers DDC HVAC Control - HVAC DDC control has become an integral part of building automation systems. Modern DDC HVAC Control is a state-of-the-art computer-controlled system that adds efficiency to the system. These Alerton controllers are used to monitor and control an air handling unit for a large building. (more…)
HVAC Tip - Having the proper humidity levels in your home or business is important not only for your health but also the amount of energy your HVAC systems use to keep you comfortable. If the humidity level is high in the summer you will not feel comfortable. If the humidity level is low in the winter you will not feel warm when the thermostat is set for an average temperature. This will result in turning the thermostat up to compensate and you will use more energy to stay comfortable. A properly designed and installed HVAC system will keep the proper levels of humidity in your home or business and save you money in energy costs by reducing the amount you use the HVAC system. For more information on humidity and maintaining the proper levels of humidity in your home please visit our humidity technical pages.
