The DFC series fan coil controller is a microcomputer controller with multi-function, high performance and independent operation.  It can connect up to 32 fan controllers and LCD group control panels or communication protocol converters into a local area network through a two-wire RS485 communication transmission method.  It uses remote or local browsers, or on-site one-to-many group control panels, which can centrally manage small air blowers scattered in various places.  It can issue group, group and stand-alone commands, and execute various monitoring records.  It has a standard built-in program, which can perform the following actions, such as timing on and off, changing the operating mode of the air conditioner, switching the operating wind speed, changing the set temperature, performing energy-saving actions, monitoring the operating status, performing hour statistics and even calculating energy consumption, etc.  It is suitable for office buildings, five-star hotels, science and technology buildings, academic research institutions or production plants, etc., where centralized management and decentralized control of small blower equipment are required.
 

【Features】
  • Built-in independent high-efficiency microprocessor (MCU) with independent operation capability.
  • The return air temperature control is adopted, and the temperature control function is not affected by the installation position of the operation panel.
  • Built-in FCnet communication interface, which can connect 32 controllers into a local network to realize centralized management and distributed control functions.
  • The built-in SCnet communication interface can be connected to a single or group control panel, which is convenient for users to increase the man-machine operation interface at any time due to the need of secondary decoration.
  • Use DFC kits provided by AIRTEK to update the firmware of the DFC. fan controller on the FCnet loop.
  • Two digital input points (BI), it can be connected to the presence sensor, water leakage sensor, house card chain signal or windmill running status feedback signal.
  • It has an analog input point (AI) with a 12-bit resolution for connecting a 10KΩ NTC thermistor return air temperature sensor.
  • With two digital output points (BO), two-pipe type (air-conditioning or heating control), four-pipe type (air-conditioning and heating control) or two-pipe type + electric chain output control points are available.
  • With automatic three-stage speed control and manual three-stage speed regulation.
  • It has air-conditioning operation modes such as air-conditioning, heating, and air supply, as well as energy-saving operation functions to save energy and increase comfort.
  • Time schedule table switch machine function.
  • With 0-12 hours fast timer shutdown function.
  • Automatic network time synchronization function.
  • Abnormal status code display and software program crash self-wake-up function (WATCH DOG).
  • With the function of power-off reset and automatically start the fan coil unit according to the address coding step.
  • With the function of power-off memory operating parameters, it will return to the original operating conditions before power-off after power is restored.
  • It has the capability of interconnection and mutual control with BACnet and MODBUS communication protocols, and can integrate all monitoring input and output points into the central monitoring system.
