The Excel 12 FCU + Light + Sunblind application is used for integrated room control. The application controls one FCU, 2 lights and 1 sunblind. One FCU: - 2 sequences configurable for HEAT, COOL and CHANGEOVER - Support of thermal actuators, floating actuators, PWM and Staged Output via triac or relay outputs - 3-stage fan via triac or relay outputs - Digital input for condensation, occupancy sensor, window contact etc. Two lights: ON / OFF switching dependent on: - Effective occupancy mode (occupied / standby / unoccupied). Effective occupancy is determined by occupancy sensor, schedule and override input. - Detected light level (LON sensor or hard wired sensor) - Manual switching (hard wired push buttons or LON wall module) - Dimming via analog outputs (this requires an HFD (High Frequency Unit) unit for dimming with 1...10Vdc input). One Sunblind: Positioning dependent on: - Effective occupancy mode (occupied / standby / unoccupied) determined by occupancy sensor, schedule and override. - Light level (LON sensor for sun light) - Manual command - Building supervisor command - Safety position dependent on: - Frost / rain from weather station or XL500 etc. - Wind speed (via LON only) - Open windows inhibits moving of sunblind (digital input or LON input). Excel 12 is available in different hardware variants (different I/O mix and power supply).
The number of applications for LonMark certification is growing rapidly. To make sure your products are on-track for certification, design conformance into them by following the LonMark Interoperability Guidelines v3.4.
The Proficiency Testing Program for Qualified Open Systems Installers, Professionals and Integrators provides a worldwide standard of proficiency for individuals that install, integrate and maintain systems utilizing LonMark certified products.
