Fujitsu RAC and VRF systems to BACnet MS/TP Interface (to CN connector)
Description
FEATURES
- BTL mark ensures full interoperability with BACnet devices.
- Supports BACnet MS/TP.
- Configurable via onboard DIP-switches.
- Quick and easy installation (Set the DIP-Switches, plug and play).
- No external power supply required.
- Allows simultaneous control with remote controller and BACnet MS/TP.
- Reduced dimensions 93 x 53 x 58 mm.
- Mountable on DIN rail, wall, or even inside the indoor unit in some AC models.
- Abstraction of Air Conditioning unit properties and functionalities as fixed BACnet Objects.
- Occupancy function for energy savings. Costs generated by HVAC systems in buildings are significant, this type of function allows to reduce them.
- Wide control and monitoring of AC unit from BACnet, including as EcoMode, Filter Alarm, Running hours, Errors, and RoomFreezeProtection.
- Supports both BACnet MS/TP and Modbus RTU. The protocol selection is made through the DIP switches.
DIRECT CONNECTION TO INDOOR UNITS
The gateway is wired directly to a Fujitsu indoor unit. This allows not only the control of the main AC functions such as operating mode, fan speed, temperature setpoint…but the monitoring of errors, alarms, and internal variables.
FAST AND EASY SET UP
Quick and easy installation. It is only a matter of wiring the gateway to the AC unit and configure the DIP-SW accordingly. No configuration software and no power supply required.
