Field Control Layer Device

Networking Fan Coil Unit controller

DFC.. Series networking fan coil unit controller is a multi-function, high performance, independent operating controller, Lan networkable up to 32 modules per Lan using Modbus RTU (RS485). A group control panel can be used as a remote master control for individual controllers or select a group to control. Using an Airtek PF-MB** Modbus–Bacnet protocol converter will allow the controller to be interfaced with a Building Management System or use a WCFB** for Intranet or Internet access.

Description

DFC.. Series networking fan coil unit controller is a multi-function, high performance, independent operating controller, Lan networkable up to 32 modules per Lan using Modbus RTU (RS485). A group control panel can be used as a remote master control for individual controllers or select a group to control. Using an Airtek PF-MB** Modbus–Bacnet protocol converter will allow the controller to be interfaced with a Building Management System or use a WCFB** for Intranet or Internet access.

Typical control function include temperature control, fan speed control, timer Off, schedule On/Off, etc Typical monitoring functions include: field temperature value, system operation status, fan speed status, Total run time accumulation, energy consumption, alarm faults, etc. DFC** series controllers are suitable for use where centralized or individual management is required, such as office building, five-star hotel or restaurants, shopping centers, science and technology building.

Features

  • High performance microprocessor and FLASH power failure memory function. Independent Operation.
  • Build in self wakeup function (Watch Dog).
  • Two sets of MODBUS RTU RS- 485 networks, one for the network FCnet (group control panel), a protocol converter or a BACnet web embedded F.C.U. controller to perform centralized management and control.
  • 2nd network SCnet for Connection to a MFC32V, MFT28U as an independent control, or cascading into a sub-network connecting to a NFC32V, NFTC28U centralized control.
  • 0~24 hours shut down timer and a daily On/Off timer, convenient for office usage.
  • 2 digital input, dry contact is acceptable, can be connected to a motion detector, key card etc. to monitor status.
  • Return Air senor included for air temperature control, control panel is not affected by the location of the control panel.
  • Air Conditioning Modes include:- Automatic or Manual Cool/Heat, Fan-Lo,Med,Hi-Auto. Energy saving modes.
  • Automatic synchronization with network time is possible from a central monitoring system or Building management system.
  • When Connected to a Group control Panel or building automation system typical monitoring and control of any point is possible.
  • Fire and abnormal temperature alarm when internal temperature rises too fast.
  • Stagger Start after power failure by node number.(Controllers will restart one by one according address number if it is in running mode
    before the power failure).
