BACnet MS/TP Gateway


   The Intesis BACnet gateway connects a single Carrier Ductless
   Indoor Unit to a BACnet control system allowing bi-directional control
   and monitoring.
   The gateway is wired directly to the Ductless 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 some internal variables.
   The product can be installed and set up in a really short time. It’s only
   a matter of wiring the gateway to the AC unit, connect 12 VDC/AC
   power supply (field-supplied) and configure the DIP-SW accordingly.
   No configuration software is required.
