Description:K-type thermo thermostat function: The product has a total of four buttons, plus, minus, SET (set button), reset button. There are two sets of digital tubes to display the actual temperature and the set temperature, respectively. All parameters are automatically saved after 5s.Specifications:Name: High temperature K type thermo thermostatPower supply: 12V DC / 24V DC / 110V-220V ACTemperature control range: -60 ~ 500 Cable length: 42cmTemperature measurement accuracy: 1 Resolution: 0.1 C.Refresh frequency: 0.5 S.Input: type K thermocoupleOutput: A 10A relayOpening size: 74mm (length) * 39mm (width) Instructions:Red digital tube: actual temperature,Blue digital tube: set temperaturePress the button to increase: increase the set temperature.Press the key to decrease: decrease the set temperature.Restore factory settings: press and hold the plus and minus buttons for 5 seconds or more to restore the original setting data.Set button (SET):1. Press SET briefly to raise the temperature by 50 C each time. Users can first press SET to quickly set the temperature near the preset temperature, and then set the temperature to the preset temperature by adding or subtracting keys.2. Press and hold SET to enter the parameter setting option. There are several groups of parameters P00 ~ P05 for users to set. After entering the parameter interface, short press SET can switch P00 ~ P05. Set the appropriate data by pressing the plus or minus key under the appropriate parameters. After setting, the system will automatically remember the data and return to the display interface.P00: H heating mode / C cooling modeP01: temperature difference backlash (0 ~ 500 )P02: temperature correction (-10 ~ 10 )P03: Maximum temperature alarm value (500 )P04: minimum temperature alarm value (-60 )P05: data lock (ON / OFF)Application 1: This thermostat can be widely used in boiler water temperature control, water dispenser water temperature control and automatic cabinet water temperature control.Application 2: This thermostat can be used for printer equipment, hatch control, and intelligent control of refrigerator air conditioners.Application 3: This temperature can be widely used in the fields of intelligent agriculture control, greenhouse temperature control, and automatic irrigation.
