BX-DT001 Digital Display Temperature Controller Instruction Manual
 

Technical parameter:
1.Parameter setting method

Press the "SET" key 3 times to enter the parameter setting state. First, the lower temperature limit "L" is displayed. Press the up key or down to change the set value. When it is set to a negative number, the minus sign flashes.

2.Instructions
Controller parameter management menu:
After 16 seconds without pressing any key, it will automatically exit the setting state, the setting value will be saved, and the current measurement temperature will be displayed on the display.

3. Mode operation:

Refrigeration: The compressor should be turned on with a delay after the power is turned on. The turn-on time is determined by the "Y" value. If the delay is cancelled, you can press the "Down button" three times. When the measured temperature ≥ the upper temperature limit, the compressor works, and the last decimal point is always on ; When the measured temperature is less than the lower limit of temperature, the compressor stops working and the last decimal point goes out.

Application example: a cold storage requires -18 degree shutdown, -15 startup, compressor delay 3 minutes, refrigeration mode. Press the "SET" key 3 times to set the lower limit temperature L to -18 degrees and the upper limit temperature to -15 degrees. The compressor delay Y can be set to 3 minutes.

Heating: The compressor should be turned on after power-on. The turn-on time is determined by the "Y" value. If you cancel the delay, you can press the down button 3 times. When the measured temperature is less than or equal to the lower limit of the temperature, the compressor works, and the last decimal point is always on; When the temperature is greater than or equal to the upper temperature limit, the compressor stops working and the last decimal point goes out.

Application example: a heating equipment requires 25 degrees to shut down, 20 to turn on, compressor delay 3 minutes, heating mode. Press the "SET" key 3 times to set the lower limit temperature L to 20 degrees and the upper limit temperature to 25 degrees. The compressor delay Y can be set to 3 minutes.

5. Fault description:

    (1) When the sensor is open or the measured temperature is less than -50 degrees, the digital tube displays -PP.

    (2) When the sensor is short-circuited or the measured temperature is greater than 50 degrees, the digital tube displays -FF.

    (3) After a failure occurs, the relay is released and the entire digital tube flashes.

    (4) After the fault is eliminated, the digital tube stops flashing and displays the temperature measurement value.
