How to use
Install the thermostat on a standard wall box and wire the supply, load and sensor according to the installation instructions for electric heating systems.

Connect the thermostat to your Wi‑Fi network and add it to the Tuya or Smart Life app to enable remote control, scheduling and device grouping.

Usage recommendations
For reliable floor temperature control, mount the floor sensor at the recommended depth and avoid placing the room sensor near heat sources or drafts. Use hysteresis and weekly programming to limit relay switching frequency and improve long-term durability. Verify compatibility of the connected heater type and ensure proper circuit protection when installing the thermostat.
