Temperature control range: The W1209 thermostat controller supports a temperature range from 50C to +110C (58F to +230F), providing precise and accurate temperature management for a variety of applications. Intelligent control: Equipped with a precision remote temperature sensor, the W1209 automatically controls power to connected equipment based on the detected temperature. It can drive coolers, heaters, or fans, and supports programming on/off set points for effective regulation. Userfriendly configuration: No programming knowledge is required. With an embedded microcontroller and tactile switches, you can easily configure parameters including trigger temperatures to tailor the thermostat to your needs. Reliable performance: The unit features a clear acrylic plastic housing and an onboard relay with a maximum switching capacity of 14V DC 20A, 24V DC 16A, or 125V AC 7A. The current temperature is displayed on a threedigit sevensegment display, and the relay status is indicated by an onboard LED. Practical attributes: Compact and durable design with a clear acrylic housing, suitable for mounting in a variety of setups. compatibility with cooling, heating, and ventilation devices, delivering dependable operation in everyday applications. Use scenarios: Seed germination or small incubator: Use the W1209 with a heater or cooler to maintain appropriate conditions for seeds or plant cuttings in a compact chamber. Electronics enclosure or test cabinet: Regulate temperature inside a small electronics enclosure by switching a fan or heater to maintain stable conditions during testing. Home fermentation or storage cabinet: Create a controlled environment for fermentation or temperaturesensitive storage by coordinating a heater or cooler with the remote sensor for consistent results.
