12. PRACTICAL APPLICATIONTUC03: TERMINAL UNIT CONTROLLER • PI: Proportonal + Integral logic to provides a more precise and accurate regulation • Functions: The Terminal Unit controller offers three modes of operation - occupied (comfort), bypass (temporarily occupied) and unoccupied (night and weekends). • Soft start: in case the internal coil sensor is connected, the possibility to enable the soft-start strategy for enhanced occupant comfort. This strategy, based on the internal coil sensor, defines the intervention point of the fan depending on the internal coil temperature avoiding to blow non or partially conditioned air. • Windows Contact: “window open” sensor may be connected to the controller to switch it to the “Energy Hold-off” mode to avoid energy waste. • Unoccupancy Sensor: in unoccupied status controller will use a reduced setpoint • Unoccupancy Contact: in unoccupied status controller will use a reduced setpoint • Output: can manage VSD fan 0..10V (Power Energy Reduction) • Supervisory: The controller can be drive by the supervisory system, then working in according to the building conditions. The controller may also be set to “off” or “unocupied” by the supervisory network or room sensor modules when the space is not in use. The controller can start regulating some time (configurable) before the range of functionality
