Features: This delicate digital display temperature controller can set Celsius mode or Fahrenheit mode. The temperature controller has the characteristic of high accuracy, high sensitivity, high stability. Wide temperature measurement range from -50 to 110 and supports high temperature protection. Can be installed directly or embedded in industrial control equipment panel, convenient and quick. Widely used in the hatching area, equipment case, air conditioning system, temperature control protection and other fields. Specifications: Input Voltage: DC12V, DC24V(Optional) Temperature Measurement Range: - 50~110 Resolution Ratio: -9.9-99.9--0.1, other temperature intervals:1 Measurement Precision: 0.1 Control Precision: 0.1 Return Difference Precision: 0.1 Refresh Rate: 0.5S High-temperature Protection: 0~110 Measurement Input: NTC (10K 0. 5%) waterproof sensor Output: 20A Relay Environmental Requirements: Temperature Requirement: -10 ~60 Humidity Requirement: 20%~85% Size: 4.8 x 2.8cm / 1.89 x 1.10in Static current: 35MA Pickup current: 65MA Methods of Use: After Connecting to the power supply and load (referring to the wiring diagram), you can supply power for the controller, the color red manifest for measuring temperature, the following color blue (or red) as required to set the temperature In the case of manifesting real temperature and please press the button set, the following setting text digital will flash and temperature, after completing the setting, please wait for 3s it will return automatically, at this time controller will automatically disconnect Relay according to the preset temperature, the this senor can meet all kinds of large power load, please make sure the line is correct The Description of Light and Digital Tube Status: Light: The off means Relay is disconnected, and the normal light on shows that the Relay has closed. Digital tube: The sign LLL is the open circuit of sensor and the sign HHH means beyond the measuring range, the controller will forcibly disconnect Relay, the sign --- means high- temperature protection The Description of Parameters Function: Please press the button SET five seconds and then it can enter to the main menu of setting, pressing STC(+)and C/F (-) can switch to P0-P8. About the adjustment of parameters P0-P8, when you need to adjust P0, firstly please press STC (+) and C / F (-) at the same time, and the P0figurewill flash, secondly please press STC (+)and C / F (-) to adjust, if done, finally please press STC (+) and C / F (-) to confirm at the same time,P1-P8 which can be set the parameters of each code like P0according to the needs of their own. The key C/F is a key for switching Fahrenheit or Celsius Press the key C/F once, and it will manifest F(Fahrenheit mode),and then press the key C/F once, it will show C(Celsius mode), the default mode is C(Celsius mode),if there is a big temperature error when you use it, maybe it is F mode. An example for setting: If you need to Control the refrigeration equipment 1: Please set into C mode in the code P0: 2:In the case of manifesting the actual temperature you should press the key SET, and the following digital of setting text will flash, then press C/F (+) and SET (-) to set the stop cooling temperature, after setting please wait for 3 seconds, it will automatically confirm to return. 3:Return difference setting: Firstly please press the key SET for five seconds all the time, and it will enter the setting main menu, secondly press STC (+)and C / F (-) to switch into P1, when switching into P1,please press STC (+) and C / f (-)once at the time, the P0figure will flash, then please press STC(+)and C / f (-)to set to difference value(return difference means that you should add several degrees to start, for instance, if the it stops when the stop setting temperature is 25 degrees, you should need to set the cooling temperature to 28 degrees, the value in the code P1should be set 3 degrees, so the return difference value is 3 degrees),after finishing that, finally please press STC(+) C/F (-) at the same time to confirm. 4:The above steps are set up, the data is automatically saved, and the final result is, in the control of refrigeration equipment, higher than28 degrees to start the refrigeration, refrigeration to 25degrees to stop. If you need to control the heating equipment: 1: Please set into H mode in the code P0. 2:In the case of manifesting the actual temperature you should press the key SET, and the following digital of setting text will flash, then press C/F (+) and SET (-) to set the stop heating temperature, after setting please wait for 3 seconds, it will automatically confirm to return. 3:Return difference setting: Firstly please press the key SET for five seconds all the time, and it will enter the settin
