W1209 Temperature Control Switch with Acrylic Housing 3 Digit Display Onboard Led And High Precision Temperature Sensor

<ul><li>Temperature Control Range】The for W1209 thermostat controller allows temperature control in a range from -50°C to +110°C (-58°F to +230°F), providing precise and accurate temperature management for various applications.</li><li>Intelligent Control】Equipped with a high-precision remote temperature sensor, the for W1209 module intelligently controls power to electrical equipment based on the detected temperature. This enables the connection of coolers, heaters, or fans, and the programming of on/off set points for effective temperature regulation.</li><li>User-Friendly Configuration】The for W1209 requires no programming knowledge, thanks to its embedded microcontroller and tactile switches. Users can easily configure parameters, including trigger temperatures, to customize the thermostat controller according to their specific needs.</li><li>Reliable Performance】Featuring a for durable construction with a clear acrylic plastic housing, the for W1209 has 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 the three-digit seven-segment display, and the relay status is indicated by the onboard LED.</li><li>Power Efficient】The for W1209 operates on a low input power of 6V to 12V, consuming a maximum of 65mA. It provides power to the module itself and offers an energy-saving solution for temperature control applications.</li><li>Energy Efficient W1209 12V Digital Thermostat Temperature Control Switch</li></ul>

for W1209 12V -50-110°C Digital Thermostat Temperature Control Switch Sensor + Case Features:*Brand new and high quality*Made of high quality material, strong and *The for W1209 is a low-cost yet powerful thermostat controller with a clear acrylic plastic housing. The module intelligently controls power to most types of electrical equipment based on the temperature detected by the included high-precision remote temperature sensor.*A cooler, heater or fan is connected to the power supply via relay contacts K0 and for K1 and the temperature on/off set point is programmed into the for W1209 using the onboard settings, increase and decrease buttons and display. Then, based on the temperature measured by the temperature sensor (included with the module) and the setpoint programmed into the for W1209 controller, the relay contacts open and close, acting as a power switch for the cooler/heater.*Although the module has an embedded microcontroller, no programming knowledge is required. 3 tactile switches allow configuration of various parameters including on and off trigger temperature.*The onboard relay can switch a maximum current of 14V DC 20A, 24V DC 16A or 125V AC 7A. The current temperature is shown in degrees Celsius via a 3-digit seven-segment display and the current relay status is shown via an on-board LED.Specification:*Temperature control range: -50°C to +110°C (-58°F to +230°F)*-9.9 to 99.9 resolution: 0.

In applications such as automobiles or RVs where the battery voltage may exceed 12V, a voltage regulator circuit such as a 1N5349A Zener diode and a 20 Ohm series resistor in the 1W range should be used to limit the voltage to 12V. Alternatively, a 12V to 9V&nbsp;converter with its input connected to the battery and its output connected to the for W1209 will provide a stable 9V DC power supply to the for W1209.Setup diagram:*description/scope/default*P0: Set heating or cooling mode / C/H / C*P1: Hysteresis setting/0. - 15C/2C*P2: upper temperature limit/110C/110C*P3: Lower temperature limit / -50C / -50C*P4: Temperature calibration / -7.0C ~ 7.0C / 0C*P5: Delayed start time/0-10 minutes/0 minutes*P6/P7: High temperature alarm/0C - 110C/off*P8: Factory reset (not included in all firmware versions.
