Specifications: Model: W1209 With Case Dimensions: 48.5 40mm Temperature Control mode: ON / OFF Temperature Range :-50 - 110 degree centigrade Resolution: When temperature is 0.1 degree, the resolution is -9.9~99.9, other temperature segment is 1 degree. Control Accuracy: 0.1 degree Hysteresis Accuracy: 0.1 degree Refresh Rate: 0.5s High Temperature Protection 0 - 110 degree centigrade Supply Voltage: DC 12V Static Current: Less than 35MA, attract current less than 65MA Output Voltage: DC 12V Output Power: 20A relay Measurement Input: NTC (10K 0.5%) Waterproof Sensor Environmental Requirements: -10 - 60 degree centigrade; Humidity 20% - 85% Instructions for use: Connect the power supply and equipment, the measuring temperature is displayed, press the "SET" button, press " + or - " to set the desired temperature (long press " + or - " to quickly increase or decrease), press "SET" to confirm the setting and return, controller automatically performs the relay ON/OFF. the thermostat output is 10A relay, meet a variety of high-power loads. LED Indicator: LED off indicates the relay off; Lighting, indicates the relay is closed. Digital LED Tubes: "LL" indicates sensor open, "HH" indicates overrange, the relay will be forcibly disconnected; "---" indicates high temperature alarm Long press the "SET" button to enter the main menu settings, press " + or - " to switching between P0-P6, then long press "SET" or 10 seconds without keystrokes to confirm the setting and return. Package Included: 2 W1209 12V DC Digital Temperature Controller Board With Case

Features:

• 100% complete machine patch, wave soldering, stable performance, good consistency.
• Embedded CPU chip (MCU), more intelligent, lower power consumption.
• Automatic power set memory (MCU built-in EEPROM memory unit).
• Control accuracy of 0.1 degrees Celsius. Have been tested for stability, consistency and reliability.
• Tips: - long press set to get menu, starts at P0 - press +/- to get next P-parameter - press set to choose that parameter - press +/- to select the value you want for that parameter - press set to accept it - long press +/- = reset to default - power-out does reset to default - default temp set is 34.5C
