TWO TYPES: This delicate digital display temperature controller can set Celsius mode or Fahrenheit mode WIDELY USED: Digital thermostat is widely used in hatching area, equipment enclosure , air conditioning system, temperature control protection and other fields CONVENIENT: display and control temperature can be set to 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: Digital thermostat can be installed directly or embedded in the panel of industrial control equipment, convenient and quick Product Description Specification: Input voltage: DC12V Temperature measurement range: -50~110 Resolution ratio: -9.9-99.9--0.1 other ranges temperature--1 Measurement accuracy: 0.1 Control accuracy: 0.1 Return difference accuracy: 0, 1 Refresh rate: 0.5s High temperature protection: 0-110 Measurement input: NTC waterproof sensor (10K 0.5% ) Output: 20A Relay Environmental requirements: Temperature requirement: -10~60 Humidity requirement: 20%-85% Machine power consumption: static current 35MA, starting current 65MA Weight: 33g / 1.2oz (approx.) Methods of use: After connecting to the power supply and load (referring to the wiring diagram), you can supply power to the controller, the color red manifests to measure the temperature, the following color blue (or red) as required to set the temperature In the case of manifesting the actual temperature and please press the set button, the text of next setting will flash and temperature, after finish setting, please wait 3 it will automatically return, at this time the controller will automatically disconnect the relay according to the preset temperature, this sensor can meet all kinds of large power load, please make sure that the line is correct Package list: 1 * temperature controller Tips: Connect the power supply 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 adjust the desired setting temperature, wait for 3 seconds after the setting is completed, and automatically confirm the return. At this point, 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 protectionProducts from GuanGuan's store
