IN485DAI001R000 – Daikin to BACnet MS/TP Gateway for VRV and Sky Air

IN485DAI001R000 – Daikin to BACnet MS/TP Gateway for VRV & Sky Air. 

The IN485DAI001R000 gateway enables seamless, fully bi-directional communication between Daikin VRV and Sky Air Conditioner units and BACnet MS/TP networks. This compact and robust device allows direct wiring to the indoor unit, offering complete control over essential air conditioning parameters such as operating mode, fan speed, and temperature setpoint. In addition, it supports real-time monitoring of internal variables, system alarms, and fault indicators, ensuring consistent performance and rapid diagnostics within HVAC infrastructures.

Thanks to the intuitive DIP-switch configuration, installation is both quick and efficient – no configuration software or external power supply is required. The device is designed for immediate deployment, streamlining integration with existing systems in building automation, commercial environments, and industrial facilities.
