With precise temperature sensing and easy configuration, the W1219 is ideal for students, engineers, hobbyists, and professionals.Key Features of W1219 Temperature ControllerDual digital LED temperature displaySupports heating and cooling modesWide temperature control rangeHigh-current relay outputAccurate NTC temperature sensorAdjustable hysteresisStable long-term performanceEasy wiring terminalsCompact and durable PCBSimple button-based configurationTechnical SpecificationsModel: W1219Operating Voltage: DC 12VTemperature Range: -50°C to 110°CControl Accuracy: ±0.1°CDisplay Type: Dual Digital LEDSensor Type: NTC ThermistorRelay Capacity: Up to 20AControl Mode: Heating or CoolingOutput Type: Relay SwitchBoard Size: Medium moduleApplications of W1219 Temperature ControllerThe W1219 digital thermostat is suitable for a wide range of applications, including:Egg incubator temperature controlAquarium heater automationRefrigerator and freezer regulationWater heater temperature controlGreenhouse climate systemsDIY temperature-controlled boxesIndustrial equipment coolingBattery thermal managementSolar system temperature controlElectronics testing environmentsWorking Principle of W1219 ThermostatThe W1219 temperature controller continuously measures temperature using its NTC sensor. Users set a desired temperature and hysteresis value. When the detected temperature crosses the set threshold, the onboard relay automatically switches ON or OFF depending on the selected operating mode.In heating mode, the relay activates when temperature drops below the set value.In cooling mode, the relay activates when temperature rises above the set value.This ensures precise and stable temperature control without manual intervention.Heating and Cooling Mode OperationThe W1219 supports two primary operating modes:Heating Mode: Controls heaters, coils, or heating elementsCooling Mode: Controls fans, coolers, or refrigeration unitsSwitching between modes is quick and simple using the onboard buttons.Digital Display and User InterfaceThe dual LED display shows:Current temperatureSet temperatureThree onboard buttons allow users to:Adjust temperature setpointChange hysteresis valueSwitch between heating and coolingThis user-friendly interface makes the W1219 easy to operate even for beginners.Relay Output and Load ControlThe built-in high-current relay allows the W1219 to control both AC and DC loads, including:Heating rodsWater heatersCooling fansRefrigeration compressorsLighting systemsAlways ensure connected loads stay within relay ratings.Power Efficiency and ReliabilityThe W1219 is designed for continuous operation with low power consumption. Its stable design ensures accurate temperature control over long periods, making it ideal for unattended systems.Educational and DIY Project UseThe W1219 thermostat is commonly used in:Arduino learning projectsAutomation training kitsElectronics labsEngineering demonstrationsIt helps users understand:Temperature sensingControl logicRelay switchingAutomation basicsInstallation and Safety GuidelinesUse a regulated 12V power supplyWire relay terminals carefullyAvoid moisture exposureMount the sensor securelyDo not exceed relay current limitsAdvantages of W1219 Temperature ControllerHigh relay current supportDual LED displayAccurate temperature sensingEasy setupWide application rangeExcellent durabilityLimitationsThe W1219 does not support wireless communication or microcontroller programming.
