## Long description

Wired two-state room thermostat TECH ST-292V3 L-5 in black is a wall-mounted temperature controller with a 3 mm glass front panel designed for binary (on/off) control of heating or cooling circuits. The unit is intended for wired installation and provides straightforward temperature regulation for residential and light commercial environments.

How to use
Install the thermostat on a stable wall surface away from direct sunlight, drafts and heat sources to ensure accurate ambient temperature measurement. Connect the device according to the system wiring diagram, ensuring mains power is isolated during installation. Set the required temperature setpoint through the front control and verify correct relay activation for the connected heating or cooling equipment. After wiring and configuration, restore power and observe at least one on/off cycle to confirm proper operation.

Position the thermostat in a representative location of the occupied zone at typical breathing height and avoid mounting it above radiators, close to windows or near ventilation outlets. Periodically clean the glass front with a soft, damp cloth and non-abrasive cleaner. For safe operation, use the thermostat with compatible relays and actuators and follow local electrical installation regulations; consult a qualified technician for complex systems or mains-level wiring.
