LM YN Digital Thermostat Module DC 5V (-10℃ to +210℃) 14°F to 410°F Electronic Temperature Control Module Switch Waterproof Sensor Probe Dual LED Display Red+Blue

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.
LEDs, LED status descriptions:
LED: Off indicates the relay off, ON means relay is closed.
Digital: Display :---: check the temperature sensor is missing or damaged;2, the heating temperature protection mode;low-temperature cooling mode protection. In protected mode relay automatically disconnected.
Use keys: temperature control panel has three buttons, pressing the + key - to set the key SET.
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.
Mode setting: Set the temperature T1, the set temperature T2.
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.
Parameter settings: the need for the user parameter settings must first hold the SET button and then give the thermostat power, to enter the parameter setting interface.
