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).
