Description
NFC-TS4316 (BACnet) with Non-volatile Programmable Filter Service Timer
NFC-TS4316 is a 4.3 inch Colour TFT Touchscreen, Proportional + Integral Fan Coil Controller with BACnet MS/TPTh connectivity up to 64 devices and supports COV subscription. The Fan Coil Controller has 2 NTC Sensor Inputs, 1 Universal input for remote changeover or changeover NTC Sensor, 2 Digital Inputs (Key Card/Occupancy and Window 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 0-10 Volts DC Outputs (1 Heating, 1 Cooling and 1 Analogue Fan Speed). The Controller supports two Pipe and four Pipe System.
The Raise Lower Outputs are TPC (Time Proportional Control with adjustable valve opening time). Builtin real time clock with backup Super-capacitor therefore eliminates the use of battery. As the controller has Sync Feature, the real time clock can be synced with Computer/Server Time Clock with BACnet Time. The NFC-TS4316 has BACnet Schedule Object. 24VAC/DC and is Wall Mount with only 25MM Thickness.
