W3230 Digital LED Temperature Controller Module Digital Thermostat Switch with Waterproof Probe Programmable Heating Cooling Electronic Thermostat Specifications: Power Supply: DC 12V/DC 24V/AC 110V~220V Temperature Control Range: -50℃~120℃ Resolution Ratio: 0.1°C(-9.9-99.9); 1°C(other range) Temperature Control Accuracy: 0.1℃ Measurement Accuracy: ±0.1°C Return precision: 0.1℃ Sensor: NTC10K waterproof sensor ; Wire: 1 meter Output: Relay Contact Capacity 10A 220V / 20A 12V / 20A 24V Environmental requirements: -10-60°C , humidity 20%-85%RH LED Displaying Color: Red/Blue Features: 1.With clear digital LED display for better readability. 2.Wide temperature measuring range. Heating or cooling control. High control precision 0.1℃. 3.All parameters setting can be saved after short circuit. 4.Relay output. 5.Can be used for domestic freezer, water tanks, refrigerator, industrial chiller, steamer, industrial equipment and other temperature-controlled system. Instructions: Indicator status: flashing indicates that the cooling or heating start-up delay, constant light indicates that the relay is closed, and no light indicates that the relay is disconnected. If the delay timer is turned on, the light blinks during the delay timer and the relay is in the disconnected state. Digital tube: ①PV digital tube is a red display digital tube, the displayed value is the actual test temperature value, when there is an abnormality, it will display the corresponding abnormality sign, display "LLL" for the sensor open display code, display "HHH" for the mandatory disconnect relay display code, that is, the measured temperature exceeds the current temperature, the relay is disconnected. The display of "LLL" is the sensor open circuit display code, the display of "HHH" is the forced disconnect relay display code, that is, the measured temperature exceeds the maximum measuring range of the product thermostat will be forced to disconnect the relay, the display of "----" for the setting of high-temperature alarm exceeds the maximum value of the high-temperature alarm display code. SV digital tube is a blue display digital tube, the value displayed is the temperature value of the relay on and off, after pressing the "SET" button, the digital tube flashes, then you can add or subtract the value through the up arrow "" and down arrow "". The value can be added or subtracted by upward arrow " " and downward arrow " ". Main menu setting: Long press "SET" button for 3s to enter the main menu setting, continue to press "SET" to switch the P0-P8 mode, press the up arrow " ", down arrow " " to set the corresponding mode. Press up arrow " ", down arrow " " to set the corresponding mode, long press "SET" button 3S, or 8s no key action will automatically confirm the return. Switch: Long press "Restart" for 1.5s to close the display and relay, press "Restart" again for 1.5s to open the display. Package Include: 2pcs W3230 Digital LED Temperature Controller Module
