Configurations

Each W7761A device can control or monitor a variety of different types of mechanical equipment. The W7761A was not intended to control staged or modulating heating/cooling coils, mixed air economizer dampers, or system fan/heat pump units. The W7761A contains inputs and outputs, but no control software. All control that would be associated with the inputs and outputs in the W7761A would be accomplished though the Excel Zone Manager and would not be suitable for VAV control, temperature control, or any control function that would require less than a 30 second update rate.

It would be suitable to control miscellaneous exhaust or ventilation fans, lighting zones that are spread out through a building which need to be linked to a start/stop time program through the Zone Manager or to enable freeze protection. The W7761A device can be connected to outdoor air temperature and humidity sensors that can be used by other Excel 10 controllers on the E-Bus or Excel 5000 controllers on the C-Bus through the Excel 10 Zone Manager. The W7761A can be used to monitor Occupancy, Window, Dirty filter, Indoor air quality, and Smoke control sensors. This allows the controllers to use their physical inputs for monitoring other elements such as return humidity, IAQ, etc. to achieve better control. The W7761A can be used to
