• Port 1#: The live wiring from the input power will be output to loads from other ports (#2/3/4) if conditions are reached, in another word, this model exists 220V AC electricity inside, thus It’s dangerous if you connect the wrong wire.
• port 2#: The relay for connecting compressor;
• port 3#: The relay for wiring defrosting unit on the evaporator;
• port 4#: The relay for Fan output;
• port 5# & 6#: input power for STC-9100 working, no need to distinguish live or zero;
• port 7#: The NTC Sensor for measuring the room temperature;
• Port 8#: Co-point for dual temp NTC Sensor;
• port 9#: The NTC Sensor for measuring the instant temperature of the defrosting unit on the evaporator;
• Copy-key: Mini USB port suit to bulk configure controllers.

How to set the temperature?

The aimed room temperature in Haswill Electronics STC-9200 was defined from "F1" to "F1 + F2" (from "SET" to "SET + HY");

You can set them in both the user interface and 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 press [UP] the key.

Please reference section 4.1 in the PDF instruction for more details.

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.

Check the F15 (FOD) value before others, like the below mindmap shows.
