3. Each MWC manages communication with up to 16 different EnOcean devices or channels.

4. Each controller can be configured to support one of two modes of operation:a. SolarTrac (ST) Mode: Relays EnOcean sensor and control information to the

SolarTrac whole-building window management automation system.b. Solar Activated Control (SAC) Mode: Utilizes the EnOcean sensor and control

information in order to feed internal automation algorithms for MechoNet window management control.

5. Powered by a dedicated low voltage 24VDC power supply or through MechoNet devices such as the IQ2 Motor or the IQ/MLC2 without adding extra power supplies.

6. Interacts with EnOcean standard Equipment Profiles as follows:a. Curtainwall Brightness Sensors (EEP A5-06-04).b. Occupancy/Vacancy Sensors (EEP A5-07-01).c. Wireless Switches (EEP F6-02-02, A5-07-01, A5-07-02, A5-07-03).

and occupancy sensors are located in places where they can reliably communicate with the MWC and provide good data.

11. SAC Mode automation algorithms for curtainwall brightness sensors support:a. Daylight automation positions window coverings for optimal visual comfort

based on daylight levels using up to 5 positions: full-up, full-down, and up to 3 configurable presets. (The default setting enables full-up, full-down and preset 2).

b. Customizable thresholds for each position are customizable including a common hysteresis setting (default: 20 percent) applied to all positions in order to prevent frequent cycling of shades as daylight conditions fluctuate.

c. Customizable delay timers also help prevent frequent shade cycling. Window coverings will only change positions if the light level is above or below a threshold for a configurable minimum timeframe. Default settings are established to be more responsive to protect against increasing light levels. Up Timer, 300 seconds; Down Timer 60 seconds.

d. Night mode provides a configurable position for the window coverings at night to support LEED light pollution requirements, privacy requirements and/or energy conservation requirements. Configurable threshold determines when night mode begins and ends based on daylight level (defaults to 200 lux) and duration (defaults to 60 minutes to enter night mode, and 30 minutes to exit).

e. Occupancy/Vacancy: (optional). While occupied: window coverings are positioned based on daylight automation settings to optimize for comfort. While unoccupied/vacant: window coverings default to a configurable position (default: Full-down) to optimize for energy conservation.

f. Automation Override: Local switch overrides suspend daylight automation for the positioned window covering for a configurable timeframe (default: 60 minutes). When the timer expires, the window covering returns automatically to the last commanded daylight automation position.

g. Retract Mode manages changes to light level based on shade position for comfort and increasing exposure of the occupant to daylight. Window coverings move up in stepped one-position increments while daylight levels drop. Each step lasts for 1 minute while the controller retests the daylight condition before authorizing the next step until the target is reached.

12. Multiple sensors (channels) can be configured to automate the same window covering control zone in order to ensure operation based on worst case comfort conditions across the zone. The window covering will be positioned based on the daylight level from the highest sensor reading.

13. The data from each sensor can also be configured to automate multiple control zones.
