Wireless thermostat as part of the EasyLink 868 system. Communication between the room thermostat and actuator is wireless via the 868 MHz frequency band, a proven industry standard known for reliable performance in residential and commercial applications. No wall chasing or additional wiring is required, making the EasyLink 868 system ideal for renovation, retrofit, and modernization projects. The ATR 4500-EasyLink features an ultra-slim design and is battery-powered (2 × AAA batteries, up to 2 years battery life). It enables simple and fast zone management via the integrated display. Automatic heating/cooling changeover is supported. Control modes include PWM and On/Off (2-point) control. Installation options include wall mounting with or without a wall bracket, or placement on a desktop stand.

Timer for Eco and Party mode, wireless RF output, wireless range up to 150 m line-of-sight (typically through 1 ceiling or 3 walls), wireless communication via 868 MHz / LoRa, selectable PWM cycle time 5...20 min, selectable hysteresis 0.1 K or 0.5 K, frost protection at 5 °C, adjustable valve protection function (duration and activation time), EN 50559 temperature limitation 5 min / 60 min when used with EV 1K-EasyLink actuator, open-window detection with adjustable temperature drop threshold and detection time, parameterization and RF commissioning via installation menu, user menu and RF commissioning directly via thermostat display.
