About LM YN Digital Thermostat Module DC 12V -10℃ To

Instructions for use: Circuit connection: Connect the power supply with reference to the circuit diagram and load, then digital (on) Display :preset temperature 1, digital control (below) shows :preset temperature 2. Temperature sensor is missing or damaged digital tube will show :- - -, make sure that the line is correct. Digital: Display - - -:1, check the temperature sensor is missing or damaged; 2, the heating temperature protection mode;3, low-temperature cooling mode protection. In protected mode relay automatically disconnected. SET Press: According to the number of different short press SET, the corresponding temperature lower limit digital flashes, blinks during the upper and lower temperature can be set through the key addition and subtraction. After setting 5s automatically save data or short press three times data can be saved. SET Press: to enter the actual temperature and the operating mode query interface, digital (on) the actual measured temperature. Digital (lower) showing the operation mode. C represents a cooling mode, H represents the heating mode, OFF means stop mode. Hot start - cooling mode: Set the temperature T1 > set temperature T2 . When the detected temperature ≥ temperature T1, the relay is closed, refrigeration equipment work; when the detected temperature ≤ temperature T2, the relay is switched off, the cooling device stops working. Cold start - heating mode: Set the temperature T1 < set temperature T2. When the detected temperature ≤ temperature T1, the relay is closed, the heating device is working; when the detected temperature ≥ temperature T2, the relay is switched off, the heating device stops working. When the preset temperature T1 = preset temperature T2, the thermostat is in OFF mode, the relay is switched off.
