Description
The NFC-TS4315 is a 4.3 inch Colour TFT Touchscreen, Proportional + Integral Fan Coil Controller with BACnet MS/TP connectivity up to 64 devices and supports COV subscription. The Unit has 2 NTC Sensor Inputs, 1 Universal input for remote changeover or changeover NTC Sensor, 2 Digital Inputs (Key Card/Occupancy, Window Input and hangeover Input), 5 Optically Isolated SSR (Solid State Relay) Outputs (1 x Raise Lower or 2 x PWM-ON/OFF and 3 Digital Fan Speed) and 3 Analogue 0-10VDC Outputs (1 Heating, 1 Cooling and 1 Analogue Fan Speed). The NFC-TS4315 supports both, 2 Pipe and 4 Pipe System. The Raise Lower Outputs are TPC (Time Proportional Control with adjustable valve opening time). The FCU has built-in real time clock with backup Super capacitor eliminates the use of battery. The real time clock can be synced with Computer/Server Time Clock with BACnet Time Sync Feature. This controller has BACnet Schedule Object (Read/Writeable) thus providing Schedule Programming with up to 6 Temperature Settings Per Day. The NFC-TS4315 works on 24VAC/DC and is Wall Mount with only 25MM Thickness.
