How to use

Connect the heater to mains power and follow the quick start guide to pair the unit with the Mill app via Bluetooth 5.2, then configure Wi‑Fi for remote control and scheduling. Use the LED display or the app to set desired temperature and schedules; built‑in PID and predictive functions will manage wattage and preheating automatically.

Usage recommendations

Install the heater at the recommended height and keep clearance around the unit for safe airflow. Do not cover the panel. Use the child lock and overheat protection features as needed. For efficient operation in poorly insulated rooms, combine scheduled heating with moderate setpoints rather than continuous high-temperature settings.
