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 housing, air conditioning system, temperature control protection and other fields PRACTICAL: The 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 fast Product Description Specification: Input voltage: DC12V Temperature measurement range: - 50 ~ 110 ℃ Resolution ratio: -9.9-99.9 ℃--0.1 ℃ other temperature intervals--1 ℃ Measurement accuracy: 0.1 ℃ Control accuracy: 0.1 ℃ Return difference accuracy: 0.1 Refresh rate: 0.5s High temperature protection: 0-110 Measuring input: NTC waterproof sensor (10K 0.5%) Output: 20A Relay Environmental requirements: Temperature requirement: -10 ~ 60 ℃ Humidity requirement: 20% to 85% Machine power consumption: Static current 35MA, starting current ≤ 65MA Weight: 33g / 1.2oz (approx.) Usage methods: After connecting to the power supply and load (referring to the wiring diagram), you can supply power to the controller, color red manifest to measure the temperature, the following color blue (or red) as needed to set 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 completing the 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 loads, please make sure the line is correct Package List: 1 * Temperature Controller Tips: Connect the power supply and the load to supply power to the controller. At this time, 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 3 seconds after the setting is completed and confirm the automatic return. At this time, the controller will automatically turn on and off the relay according to the setting. The thermostat output is 10 relays, which can meet the requirements of high power loads. The connection is correct. The status description of the light and digital tube: Indicator light: The indicator light off means the relay is disconnected, and the normal indicator light on indicates the relay has closed. Digital tube: LLL sign is the open circuit of the sensor, and HHH sign means beyond the measuring range, the controller will forcibly disconnect the relay, and --- sign means high temperature protection
