DC 12V Digital Thermostat Temperature Controller Regulator Thermoregulator Incubator NTC Sensor W1209WK W1209 Switch Module(W1209 Red)

Temperature ControllersW1209WKInput Voltage: DC 12VRed + Blue Dual DisplayCelsius / Fahrenheit Dual ModeTemperature Measurement Range: -50 Celsius~-110 CelsiusCable length:30CMIndicator light, digital tube status description:Indicator light: Off means the relay is off, steady light means the relay is closedDigital tube: The above shows that LL is the sensor open circuit; the display HH is out of the measurement range. The temperature controller will forcibly open the relay; display - for high temperature protection.InstructionsKey Description: The SET button is also the setting button; the C/F button is the Fahrenheit and Celsius conversion buttons.Press the SET button while the actual temperature is displayed, the lower setting number flashes (the lower setting temperature flashes), then SET(+) C/F(-) to set the desired setting temperature. 3 seconds automatically confirms the . At this time, the controller automatically performs relay on/off according to the set temperature. The rated output of the thermostat is 12V20A relay, which satisfies all kinds of high power. Please make sure the line is correct.Under normal working conditions, short press the C/F (-) button to switch between Fahrenheit and Celsius.In normal working environment, press and hold the SET button 5S to enter the main menu settings, press SET (+), C / F (-), to select P1-P8 mode, after confirming the mode, press and hold SET (+) , C / F (-) enter the mode setting parameters. At this time, the number below is flashing, and then the SET (+), C / F (-) button to adjust the size of the parameter, automatically save and exit after 3S. The setup is complete.Package Included:1 x W1209WK Digital Thermostat1 x NTC Sensor ProbeW12091. product featurescomplete machine patch, wave soldering, stable performance, good consistencywith a shell, more beautiful and practicalembedded central processor chip (MCU), smarter, lower power consumptionpower-off setting automatic memory (MCU built-in EEPROM storage unit)control accuracy of 0.1 degrees Celsiusthe setback of 0.1, can control the decimal (0.1-15.0)2. technical parametersTemperature control range: -50~110°CResolution: -9.9~99.9 when 0.1 °C Other temperature range 1 °CTemperature measurement accuracy: 0.1 °CControl accuracy: 0.1 °CHysteresis accuracy: 0.1 °CRefresh rate: 0.5 SDisplay type: 0.28 inch three digital tubeInput power: DC 12VMeasurement input: NTC (10K 0.5%) Waterproof sensor Line length 300mmOutput: 1 relay output, 5A 250VAC, 20A 16VACEnvironmental requirements: -10~60°C Humidity 20%-85%Size: 47.5*18.5*31.5mmPower consumption of the whole machine: quiescent current: 10MA Pull-in current: 65MA3. the method of useConnect the power supply and equipment to supply power to the thermostat. At this time, the temperature is displayed. Press the SET button, the display temperature will flash, press +- to set the desired temperature (press +- to quickly raise and lower) After finishing, press SET to confirm the . At this time, the thermostat automatically performs relay on/off according to the setting!4. the indicator light and digital tube status descriptionIndicator light: The yellow indicator light is always on, indicating that the relay is closed.Digital tube: Display LLL is the sensor open circuit, please follow the instructions to connect the sensor; display HHH is out of the measurement range, the thermostat will force the relay to open5. parameter function descriptionPress and hold SET for 5 seconds to enter the main menu settings, press +- to switch P0...P6, long press SET or 5 seconds without key action, the thermostat automatically confirms the .P0 cooling and heating mode ( is cooling mode)P1 hysteresis setting ( value 2 ° C)P2 upper temperature setting upper limit ( value 110 °C)P3 lowest temperature setting lower limit ( value -50 °C)P4 temperature correction ( value 0 ° C)P5 delay time ( value 0 minutes)Restore settings: In the off state, press and hold the + and - buttons simultaneously, then turn on the power, the digital tube displays 888 and all parameters are restored to the defaults.Package Included:1 x W1209 Digital Thermostat1 x NTC Sensor Probe==========Battery Included : NoHigh-concerned chemical : NoneIs Smart Device : NoCable Length : 1mUse : IndoorCertification : NoneDisplay Size : 1.9 Inches & UnderFunction : LED Display Temperature Control Switch ModuleType : NTC Temperature Sensor Meter
