Toshiba VRF and digital air conditioning systems communication module for Modbus interface.
IntesisBox INMBSTOS001R000 enables full bi-directional monitoring and control of operating parameters of Toshiba VRF and digital air conditioners from Modbus RTU (RS-485) networks.
INMBSTOS001R000 is designed to integrate Toshiba air conditioning into building automation, BMS, and PLC environments that use Modbus RTU (RS-485 / EIA485). Instead of keeping HVAC isolated in a proprietary control layer, the gateway exposes key control points and feedback via Modbus registers, providing a consistent interface for engineering, commissioning, and long-term operation—especially in multi-zone installations where repeatability matters.

Technically identical product – only the name / SKU has changed.
The gateway is wired directly to the indoor unit, which enables both control and real-time supervision. It supports control of main AC functions such as operating mode, fan speed, and temperature setpoint, while also providing access to errors, alarms, and selected internal variables. Bi-directional communication helps build reliable BMS logic: the supervisory system can send commands, read back statuses, and react to service events based on diagnostics.
INMBSTOS001R000 is built for fast deployment. Installation and commissioning are limited to wiring the gateway to the AC unit and setting the required DIP-SW options. No configuration software and no external power supply are required, reducing system complexity and speeding up field work. A consistent Modbus register mapping approach (used across AC brands) helps standardize integration and improves scalability across projects and sites.
On the Modbus side, the device operates as a Modbus Slave, making it straightforward to add into existing RS-485 lines together with other Modbus devices. The gateway also allows simultaneous use of the control panel and MODBUS RTU, supporting a practical balance between centralized supervision and local user operation.
