Specification: 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 tat 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 tat panel has three keys, keys + keys - SET keys Key + : fa Package List
