ComfortID control system provides affordable, real-time hvac control, says the company. It uses direct digital control (ddc) to let equipment and components communicate with one another. The hvac system responds with modifications to temperature and ventilation levels, providing constant indoor comfort, the company says. Microprocessors evaluate data collected from sensors placed throughout a building, interpret the information, and direct the appropriate hvac response, controlling functions like outdoor air intake, damper position, and fan speed.
