Constant pressure controllers
As the “brains” of Tjernlund’s vent system, the CPC-3 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. The controller also has a built in alarm and alarm contacts.
The brochure offers an example of a 27% installed savings with a CPC-3 controlled system vs. a system without it. In addition to highlighted features, the brochure also includes a sequence of operation and programming options.
The CPC-3 brochure is available via the Tjernlund Products at website or by calling 800-255-4208.
