Temperature control range: 50°C to +110°C (58°F to +230°F). The W1209 thermostat controller provides precise, reliable temperature management for a variety of applications. Intelligent control: Includes a precision remote temperature sensor and automatically powers connected equipment based on the detected temperature. Suitable for cooling, heating, or fan applications, with programmable on/off setpoints for effective regulation. Easy to configure: No programming knowledge required thanks to an embedded microcontroller and tactile switches. You can quickly set parameters, including trigger temperatures, to tailor the thermostat to your needs. Reliable performance and clear status: Durable clear acrylic housing with an onboard relay. Relay switching capacity: 14V DC 20A, 24V DC 16A, or 125V AC 7A. The current temperature is shown on a threedigit sevensegment display, and the relay status is indicated by an onboard LED. Practical use scenarios: Enclosures and equipment cabinets requiring stable environmental conditions by driving a heater, cooler, or fan as needed. Small refrigeration or heating setups, such as compact coolers or heater boxes, controlled by setpointbased switching. DIY climate control projects, including incubators, seedling boxes, or fermentation chambers, where a simple, reliable thermostat is needed without programming.
