In order to simplify integration of terminal

|| The Price multipoint flow sensor is
compatible with most DDC controls on the
market and is recommended for applications
requiring factory mounting of DDC controls.
Price will also provide operational checks
and calibration of control components
before factory shipment, on request.
These additional services performed in the factory ensure an operational unit and reduce field labor. Price can also supply its own brand of DDC controls called the Price Intelligent Controller (PIC). This controller can operate stand alone or be networked to a Building Automation System (BAS) using the ASHRAE standard BACnet. The PIC controller is shown below on the A terminal unit.
