How to set the temperature?

The room temperature was defined from "F1" to "F1 + F2" (from "SET" to "SET + HY");

You can set them in the user interface or the Admin Interface, below is the method for the administrator.

  1. Enter the Admin Interface: hold the [SET] key and the [Down] key at the same time for 10s; you will see the code "F1" ("SET").
  2. Press the [SET] key to check the current value, and press the [Down] key or the [Up] key to change the F1 value;
  3. Press the [SET] key to save the new data, and back to the menu list, you will see the code "F1" ("SET") again.
  4. Switch to the "F2" ("HY") code by pressing [UP] the key.

Please reference section 4.1 in the PDF instruction for the "setting method in user interface".


How to Configure the Defrosting

This unit controls the defrosting by Time and Temperature.

  1. Temperature Condition: the evaporation sensor temperature is lower than the preset "defrosting Stop temperature" F8 (DTE), which is a significant value to prevent over defrost.
  2. Time Condition 1: the real-time passes the preset interval time F6 (IDF), a regular parameter for almost all defrosting thermostats.
  3. Time Condition 2: If the "defrosting method" you take is the hot gas from the compressor reverse rotary when F10 = 1 (TDF= HTG), it will count the compressor's last stops moment plus F5 (AC), which is a protective value to avoid the compressor frequently startup and stops.

STC-9200 Error Code

    • E01 and E02 mean temperature sensor can not get valid data, maybe the thermistor cable is open or short, E01 for the room sensor, E02 from defrosting sensor;
    • HHH/LLL code means the sensor measured temperature value beyond the measurable range; please find the detailed formula from the STC-9200 instruction.
    • Number readout flash means room sensor exists a problem; the detected instant temperature exceeds the allowed range; please check your compressor and change the working status if necessary after fixing the temp sensor.
Most errors could be solved by replacing a new sensor, please find more solutions from the below user manual.
