DFD.. series fan coil unit controller is a multi-functional, high-performance, independent operation microcomputer controller. It can connect up to 32 fan controllers with LCD group control panel or connected to a local area network by RS-485.
When connect the FCU panels to a web based master controller PF-BMxx, user can control and monitor FCUs by using a browser.
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 fan coil 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 DFD kits provided by AIRTEK to update the firmware of the DFD. 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 (When work with PF-BMxx) and MODBUS communication protocols, and can integrate all monitoring input and output points into the central monitoring system.
