Benefits of Building Automation Systems - Modern buildings use DDC controls for building automation systems. Building automation systems offer energy savings because they are energy management systems. These systems allow management to automatically control many processes involved with HVAC systems, lighting, and emergency systems. The systems are generally hooked up to the internet so monitoring and control can be done worldwide. (more…)
Air Handler Equipment DDC Controllers – These controllers will control an air handler once the wiring is completed. The panel is freshly mounted and waiting for the technician to run the piping and pull the wire from the control points. Other points, such as outside air, temperature sensors in piping or ductwork, flow meters, actuators, or other control points can be terminated to these controllers and the data collected from those input points can be networked over the entire building automation system through the communication trunks.

Economizer Systems and HVAC Control - Direct Digital Controls Systems in HVAC control have taken leaps and bounds in the last few years. Especially so in being user-friendly, ease of designing systems, troubleshooting system problems, and increasing efficiency over the older energy management systems. When discussing the increasing efficiency of systems the idea of economizing always comes up. (more…)
DDC Automated Logic M-Stack - This Automated Logic M-Stack provides a control for multiple pieces of HVAC equipment and integrates network communication all in one single stack. This direct digital control system is integrated with pneumatic controls. DDC allows automated HVAC control processes to take place and adds higher efficiency to an HVAC system. (more…)
HVAC Tip - A thermocouple is commonly used in standing pilot gas furnaces and water heaters are technically referred to as a copple element and produces millivolts when heat is applied to the tip. This millivoltage is necessary to keep the pilot valve inside the gas valve open. If the pilot flame goes out, the thermocouple stops generating millivolts. Without the millivolts, the valve closes thus preventing gas from escaping when there is no flame. Thermocouples fail because of oxidation. It is recommended that you keep the pilot lit throughout the year to prevent excess oxidation. The thermocouple can be found in many different types of gas furnaces, gas logs, and gas water heaters.
