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 that delivers reliable performance in residential and commercial applications. No wall chasing or additional wiring is required, making the EasyLink 868 system an ideal solution for renovation, retrofit, and modernization projects. The ATR 4800-EasyLink features an ultra-slim design and is battery-powered (2 × AAA batteries, up to 2 years battery life). It enables simple and intuitive zone management via the integrated display. Features include automatic heating/cooling changeover, programmable time schedules including Auto mode (weekly program), Holiday mode, Home mode (day program), and a timer function for temporary Eco or Party mode operation. The control method can be configured for PWM or 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, automatic weekly program, home day program, holiday 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.
