TWO TYPES: This delicate digital display temperature controller can set Celsius mode or Fahrenheit mode CONVENIENT: display and control temperature can be set at 0.1. It is convenient to install and the wiring is simple HIGH TEMPERATURE PROTECTION: Wide temperature measurement range from -50 to 110 and supports high temperature protection EASY TO INSTALL: Can be installed directly or embedded in the industrial control equipment panel, convenient and quick Widely used: widely used in hatching area, equipment enclosure, air conditioning system, temperature control protection and other fields Specification: After connecting to the power supply and load (referring to the wiring diagram ), you can power the controller, the manifest red color to measure the temperature, the following blue (or red) color as needed to adjust the temperature In the case of manifesting the actual temperature and please press the set button, the following setting text will flash and the temperature, after finishing the setting, please wait 3 it will return automatically, at this time the controller will automatically disconnect the relay according to the preset temperature, this sensor can meet all kinds of large power loads, please make sure the line is correct Package list: 1 * temperature controller Tips: Connect the power and load to power the controller. At this point, the upper red display shows the measured temperature and the lower blue (or red) display shows the desired set temperature. Press STC (+) C / F (+) to set the desired setting temperature, wait for 3 seconds after the setting is completed, and automatically confirm the return. At this time, the controller will automatically turn the relay on and off according to the setting. The thermostat output is 10 relays, which can meet the requirements of high power loads. The connection is correct. The description of the status of the light and digital tube: Indicator: The indicator off means the relay is disconnected, and the normal indicator on indicates that the relay has closed. Digital tube: LLL sign is the sensor open circuit, and HHH sign means beyond the measuring range, the controller will forcibly disconnect the relay, the - -- means high temperature protection The description of settings function: Please press the SET button five seconds, then it can enter the setting main menu , pressing STC (+) and C/F (-) can switch to P0-P8.
