The Honeywell W7753A2002 is a direct digital controller for unit ventilators with staged, floating, or pulse width modulation output using pre-programmed cooling, economizer, heating, and ASHRAE cycles I, II, or III algorithms.
Features
The Honeywell W7753A2002 uses the standard Echelon® LonMark Unit Ventilator functional profile for openness and interoperability with Lon Mark devices. Applications include unit ventilators with up to two stages heat/cool; floating heat/cool/economizer, pulse width modulating (PWM) heat/cool/economizer; ASHRAE Cycles I, II, III. The W7753A2002 can also be used for indoor air quality control using an external sensor/control and economizer minimum position reset. Two included digital outputs can be used as free points controlled by the network for lighting, exhaust fan. Controller provides optional energy-saving setpoints for heating/cooling in unoccupied/occupied and standby modes. Features include optional control sequence shutdown via window/door open digital input, on-board status LED, UL94-5V flame-retardant construction, on-board network jacks for quick commissioning and troubleshooting using the E-Vision configuration tool, and free topology transceiver (FTT) for flexible installation
