Wall-mounted indoor thermostat — compact, space-saving design for simple installation on interior walls. Ideal where a durable, visible control is needed without taking up floor or shelf space. Precise temperature control (+5 to +40 °C) — set and maintain comfortable indoor temperatures within the specified range to suit different seasons and personal preferences. Designed for space heating auto-control systems — integrates with heating control circuits to automatically regulate room temperature, improving comfort and reducing unnecessary runtime. Built-in indicator light — clearly shows when the heating function is active so you can monitor operation at a glance. External sensor included (300 cm cable) — the supplied probe lets you measure temperature away from the thermostat body (for example near the floor, in a different zone, or inside an enclosure) for more accurate control of the conditioned space. Safety and energy efficiency — system meets safety and energy-saving requirements to help maintain safe temperatures while minimizing energy use. Key benefits — why this thermostat solves problems: Consistent comfort: keeps room temperature steady within the +5/+40 °C range, avoiding cold or overheating. Energy control: automatic regulation reduces heating runtime and helps lower energy consumption. Reliable status feedback: the indicator light makes it easy to confirm when heating is engaged. Accurate sensing: the 3 m external probe enables correct temperature measurement where it matters most. Practical applications / use scenarios: Residential living areas: wall-mount in living rooms or bedrooms to maintain a stable, comfortable temperature and reduce heating waste. Zoned heating control: use the external sensor to monitor and control specific zones (basements, sunrooms, or enclosed spaces) where room temperature differs from the thermostat location. Small commercial or office spaces: integrate into space-heating systems to provide reliable automatic control and visible status indication for staff. Features summary: Mounting: indoor wall-mounted design for easy placement Temperature range: +5 to +40 °C Function: automatic control for space heating Indicator: built-in light indicates when heating is on Sensor: external probe with 300 cm cable included Focus: safety, energy efficiency, and comfortable temperature control Installation note: designed for indoor use and built to be a compact, unobtrusive control point for existing space-heating systems.
