DFR Series
Field Control Layer Device
RF Wireless Networking Fan Coil Unit Controller
Description
DFR series RF wireless is a Stand Alone, multi-functional Fan Coil controller, economical to install with minimal wiring. Communication is via wireless RF transmission and there can be up to 16 FCU controllers with each PF-MR11 device or NFR16P wireless remote. When linked to a wireless LAN network, a centralized management system can carry out control and monitoring functions remotely.
When connected to a MFC or NFC family of control panels or NFR16P wireless remote, the user can change group or individual control functions of the DFR controller, such as start/stop, air conditioning mode, fan speed switch, set temperature, time delay shutdown.
Features
- Operates with a 32 bit high effect microprocessors (MCU).
- Incorporates a RFnet two-way communication channel, send and receive, use a PF-MR11 or NFR16P wireless remote control, links into a wireless LAN.
- With a MSnet communication interface, the operator panel MFC, MFT, NFC can be connected to the DFR for local control.
- Communication distance up to 100 meters (Line of Site). The external antenna design allows for greater coverage.
- Easy installation, minimal wiring.
- A dry contact input or infrared sensors is typically used for energy-saving by automatically turning OFF the system.
- Separate temperature sensor from the control panel insures the location of the control panel is not critical..
- Shut down timer is used for delayed STOP of the system..
- Automatic Shut Down if temperature rises above more than 55 ℃.
- Memory retention on Power Failure.
- Stager start after power outage (Uses Node Number for stager start up).
- On-Board 5A fuse.
