Start of Sales for the ARU30W Wireless Room Unit

As of August 14, 2026, sales of our ATMOS ARU30W wireless room unit have officially started.

At first glance, the ARU30W room unit is identical to the standard wired ARU30 room unit.

However, the ATMOS ARU30W primarily enables a wireless connection via the ATMOS WG1000 wireless gateway to the ATMOS ACD 03/04 equithermal controller.
Due to its touchscreen display, the ARU30W unit requires a continuous power supply—either via an external power supply/adapter, or by utilizing power directly from the ACD 03/04 controller (for more details, see the manual HERE).
During wireless operation, the room unit also functions as a signal repeater for other ATMOS wireless devices.

The ARU30W also offers the option of a classic wired connection to the ACD 03/04 controller via the ATMOSNET wired communication line.

With the launch of this new wireless device comes a new software version (FW – firmware) designated FW 2.06. This upgrade not only addresses the connection and functionality of the ARU30W room unit, but also brings many adjustments and improvements for regular users of the ACD 03/04 equithermal regulation. We therefore recommend updating every ACD 03/04 controller to the latest firmware version, available for download HERE.
