Overview

The Room Control Display Rio Lite 4" is a compact room-control panel in the PIERRE product range, designed for spaces where a simple, dedicated control interface is required. Powered by the PIERRE Smart Chip, it features a 4-inch, 480 × 480 touch screen and supports a single dashboard for intuitive room control.

The built-in temperature and humidity sensors provide real-time room environment measurements, making Rio Lite ideal for monitoring and controlling room conditions. An integrated brightness sensor automatically adjusts the display brightness to suit the surrounding light conditions.

Rio Lite supports flexible power options, including Power over Ethernet (PoE), 12 V DC, and 24 V DC, simplifying installation across different project requirements.

It communicates via Ethernet or Wi-Fi, also serves as a gateway for PIERRE Wave products (Zigbee 3.0).

The display uses the same physical dimensions and installation requirements as the standard Rio 4", fitting an 86 × 86 × 50 mm back box with 60 mm fixing centres. It has an IP20 rating and operates at temperatures from 0 °C to +40 °C, with relative humidity of 5–90% (non-condensing).
