W3002 12V 24V 110V 220V Professional Digital LED Temperature Controller 10A Thermostat Regulator Control Switch W3002 Feature: Heating/refrigeration modes, users can set the start/stop temperature freely;With large and clear LED display for better readability Easy to use:Three buttons for easy operation, to set start temperature, stop temperature, corrected temperature, delay start time. Two Work Mode:Heating ( start temperature is less than stop temperature), Cooling ( start temperature is above than stop temperature) Applycation:Waterproof sensor, can be used to detect water or other liquid non-corrosive. objects temperature, for aquaculture,ornamental fish and other. Specifications: 1.Temperature measurement range: - 50 ~ 110C 2.Temperature control range: - 50 ~ 110C 3.Temperature measuring accuracy: plus or minus 0.2 C 4.Temperature control precision: plus or minus 0.1 C 5.Measuring input: NTC10K L = 1 meters waterproof probe 6.Input power: according to the classification of choice 7.Output power: according to the classification of choice 8.Appearance size: 60 * 45 * 31 mm 9.This Temperature Controller come with 1meter waterproof sensor 10.This item sensor use 2P plug, very easy to change, you also can choose more long sensor Operation Instructions: Set the start temperature; press the up button on one time to show the starting temperature, press the upper key for about 3 seconds, start temperature and digital flicker, and set the required temperature value through the upper and lower keys. Set the stop temperature: press the next button to show the stop temperature, press the key for about 3 seconds, stop the temperature, and digitally flicker, and check the required temperature value through the upper and lower keys. Restore factory setting: under the condition of electricity, at the same time hold down the upper and lower keys, the digital tube display 888 then automatically jump to the detection temperature, can restore the factory setting; Start temperature stop temperature = refrigeration mode Prompt: When setting up the heating mode, if the temperature value is set upside down, the output indicator will not be lighted and the load will not work. If the above situation occurs after the completion of the setup, we can check whether the temperature value of the set is reversed. Package Included: 1*W3002 Microcomputer Digital Thermostat Notes: There are four models to choose from: the product is divided into isolationversion and normal version. The isolation version has one more transformer and the product performance is more stable. The transformer is an isolated power supply. The normal version is a capacitive solution and the capacitive version is a non-isolated power supply
