The W7620 Single Zone Control System is Honeywell’s new line of single zone control products. The W7620, can conveniently monitor and control individual HVAC zone equipment. System features include CNAP (Control Network Automation Protocol) communication, application flexibility, DDC (Direct Digital Control), network integration, easy installation and programming, and increased equipment reliability. The basic W7620 Single Zone Controller has built-in capability to process I/O (Input/Output) data, run DDC programs, and communicate along with other devices on the CNAP network. See W7620 family photo. The W7620 Single Zone Controller is a DDC device. DDC has a control loop which periodically updates the outputs as a function of a set of measured inputs and a given set of algorithms. The advantages of DDC are: Control The W7620 Single Zone Controller provides sophisticated control loops for accurate control of single zone equipment that prevents temperature droop and provides greater comfort in the zone. Maintainability Use of a single programmed computer reduces requirements for calibration checks because there are fewer interconnected analog components. Periodic recalibration is automatically performed. Reliability EEPROM (Electrically Erasable Programmable Read Only Memory) and EPROM (Erasable Programmable Read Only Memory) hold the control program and parameters eliminating the need for a battery. Communlcatlon Networking controllers together on a RS-485 network using CNAP software provides information for integration of control functions, monitoring, trending, alarming, and report generation. The W7620 Single Zone Controller can be applied in a stand-alone environment with distributed zone control and hard-wired time-of-day functionality It can also be applied as part of a networked system via connection to the RS-485 CNAP network. The CNAP network enables communication to multiple W7620 Zone Controllers as well as to other controllers, such as the W7600 Control Module, 47640 NIU or a Q7650 PC Interface Card in a PC with ZM7603 Remote Monitoring software. Refer to the ZM7601 Configuration Tool/ZM7603 Remote Monitoring software specification sheet, Form 63-4272, for a more detailed description. Through the CNAP network, the controller can be provided with information specific to its controlled zone only, or with information necessary for a group of zone controllers. ZM7601/ZM7603 software can, in turn, be provided with periodic information on any controller data for monitoring, data gathering, or report generating. See Figure 1. The W7620 Zone Control System was designed for application flexibility. Simply by changing the algorithm which is stored in EBPROM and by determining the input and output requirements, the same W7620 controller can be applied in a variety of applications. ‘Ike W7620 Baseboard provides input dedicated to the T7660 Space Temperature Sensor (space temperature, remote setpoint, bypass switch with LED feedback, and CNAP communication connection...
