Insert two AA batteries (included) and connect the control panel to a USB power source. Use the rotary dial with display for local adjustments or pair the head with the Shelly app via Bluetooth and the control panel for Wi‑Fi remote control. Configure schedules, enable Boost mode locally via the dial or remotely in the app, and add optional external sensors to improve temperature regulation.

Recommendations

For reliable performance place the thermostat on an unobstructed section of the radiator and avoid positioning external sensors in direct sunlight or near doors that may cause drafts. Replace batteries when the app indicates low battery and ensure the control panel remains connected to a stable USB power source for continual Wi‑Fi access.
