Field Control Layer Device
Networking Fan Coil Unit controller
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).
