A brochure on the CPC-3, a constant pressure controller, is available. The controller automatically monitors and adjusts fan speed to provide modulating, demand-based performance. According to the manufacturer, the brochure is a must read for HVAC specifiers searching for alternatives to fixed speed fans for exhaust and supply air applications. As the “brains” of the company’s vent system, the controller simultaneously checks pressure differentials and adjusts fan speeds to maintain a user adjustable set point. Up to 16 individual boilers, water heaters, or clothes dryers can be interlocked as well as a motorized damper/louver. In addition to highlighted features, the brochure also includes a sequence of operation and programming options.
