C. Suggest Load Power

4.5. Copykey (Optional)
A. Upload to Controller

1. Insert the Copykey, Press the key, the display shows “UPL”;
2. Now Press the key to upload data will show “END” once finished;
3. Shut down the controller and pull out the Copykey.

B. Download from Controller

• If a parameter in Copykey exists error or is in the wrong format, the display shows ERR.

Configurations

5.1. Code and Function Menu
Hold the + keys at the same time for 10s to enter the Admin Interface The codes SET and HY (F01 and F02) are the user menu. Others are admin menu, ref 4.1 A & C

The EN code menu and the F code menu are same, just for satisfy different clients.

5.2. When will the Defrosting Starts / Stops?
STC-9100 temperature controller user manual from Haswill Electronics teaches you
A. Defrost relay will close/on when reaching all the below conditions

• The time should later than: the compressor last stops moment + if the defrosting
  Mode was thermal air / Hot Gas ( ).

• The defrost sensor temperature < Defrost stop temperature (in )

• Time passed the defrosting cycle time ) or forced defrosting beginning
  B. Defrost relay will open/off when reaching any one of the below conditions

• The defrost sensor temperature ≥ Defrost stop temperature (in )

• Passed the defrosting Lasting Time (MDF/F07)

5.3. When will the Compressor Start / Stop?
The room temperature was supposed to keep at the range from “ ).”
The time should be later than the compressor last stops moment + AC/F05, and then
A. If TDF/F10 = EL/0 (like an electric heating wire wound around the evaporator)

or defrosting beginning ; or forced Refrigeration is over.
Not in defrosting| Room Temp

B. If (Hot Gas from the compressor Reverse Rotary), 1 more status than A
