Excel 10™ W7753A Unit Ventilator Controller
Excel 10™ W7753A unit ventilator controllers are designed for unit ventilators with staged, floating, or pulse width modulation output using pre programmed heating, cooling, economizer, and ASHRAE cycles I, II, or III algorithms.
Overview
Excel 10™ W7753A unit ventilator controllers are designed for unit ventilators with staged, floating, or pulse width modulation output using pre programmed heating, cooling, economizer, and ASHRAE cycles I, II, or III algorithms.
Features & Benefits:- Uses standard Echelon® LonMark® unit ventilator functional profile for openness and interoperability with LonMark 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
- Two unused digital outputs can be used as free points controlled by the network for lighting and exhaust fan
- Can be used for indoor air quality control using an external sensor/control and economizer minimum position reset
- Provides optional energy-saving setpoints for heating/cooling in unoccupied/occupied and standby modes
- Optional control sequence shutdown via window/door open digital input
- Onboard network jacks for quick commissioning and troubleshooting using the E-Vision configuration tool
- Onboard status LED
- Free topology transceiver (FTT) for flexible installation
- UL94-5V flame-retardant construction
- UL 916
