Specifications: Material: electronic element Voltage:DC 12V/24V /110-220V(Optional) Power:120/240/1500W (Optional) Weight: Approx.48g/1.7oz Package list: 1 x Digital Thermostat Temperature Alarm Controller Sensor Circuit connection: refer to the circuit diagram to connect the power supply and load. At this time, the digital tube (top) displays the actual measured temperature value, and the digital tube (bottom) displays the preset temperature. If the temperature sensor is missing or damaged, the digital tube will display "-- --", and the buyer must check whether the temperature sensor is installed before using it. The temperature control output is a 10A relay, which can meet various high-power loads. Please make sure the circuit is correct. Indicator light, digital tube status: Indicator light: off means the relay is disconnected, and on means the relay is closed Digital tube: display "-- --", 1. Check whether the temperature sensor is missing or damaged 2. High temperature protection of heating mode 3. Low temperature protection in refrigeration mode The relay in protection mode is automatically disconnected. Use of keys: the thermostat panel has three keys, keys + keys - SET keys Key + : fast accumulation of values Key -: to achieve the rapid decline of the value Press Restart: Restart the button Setting key SET: realize the setting temperature setting interface and parameter setting interface of the two-layer interface SET short press digital tube (bottom) to SET the temperature quickly. Default - 20℃and 0℃, 20℃and 40℃, 60℃, 80℃, 100℃, and other data set convenient user quick call. For example: users need to SET 68.8℃, first short press SET to 60℃, and then through the buttons and fine-tune to the corresponding temperature. After setting, wait for 5s to automatically store data in memory. Compared with the first generation of thermostat, the second generation is more convenient and flexible to operate, and the dual LED display of the actual temperature and the set temperature is more convenient to observe. Long press SET to enter the parameter setting interface. P0-p5 is the corresponding parameter setting item. Under the parameter setting menu, short press SET can be used to switch p0-p5. To modify a parameter, simply switch to the corresponding item and set it by adding or subtracting keys. Long press SET to save data after setting, or wait 6s to save data automatically. Reminder: P3 setting 1 means that the thermostat will stop running for 1 minute, and long press SET to trigger again. P4 setting 1 means the thermostat will start working after 1 minute. After setting the digital tube will not light, until 1 minute after the normal work. Long press SET to trigger again. P5 is set as OFF by default. Once the user sets the temperature, the P5 can be set as ON to prevent others from changing it at will. Once set to ON, the data will be locked and the P5 will be set to OFF when it needs to be set again. Package List
