NFC-TS4311 - Touchscreen Fan Coil Controller, 24VAC/DC

On request
£79.00 £94.80

The NFC-TS4311 is a wall-mounted Fan Coil Controller with a 4.3" Colour Touchscreen and a thickness of only 25mm.

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 Changeover Input), 5 Optically Isolated SSR (Solid State Relay) Outputs (1 x Raise Lower or 2 x PWM-ON/OFF and 3 Digital Fan Speed), 3 Analogue 0-10VDC Outputs (1 Heating, 1 Cooling and 1 Analogue Fan Speed) and a built-in real time clock.

The NFC-TS4311 supports both 2 Pipe and 4 Pipe Systems and the Raise Lower Outputs are TPC (Time Proportional Control with adjustable valve opening time).

The integrated backup Super capacitor provides up to 48 hours of power and eliminates the requirements of a battery.
