4.2 Control temperature setting (factory value 5℃):
◆In the running state, press the "SET" key once, the "set" indicator light is on, and the set temperature value is displayed at this time. Press the "▲" key or "▼" key to change the temperature setting value. After setting, press Click the "Unlock" button to save and exit.
4.3 System menu settings:
◆In the running state, press the "▼" key and the "SET" key at the same time for more than 3 seconds. The window displays "F1", the "set" indicator light is on, and the system enters the parameter menu setting state, by pressing the "▲" or "▼" key The setting parameters of the displayed items can be changed. After setting, press the "Unlock" button to save and exit.
5. Function Description
5.1 Temperature control
◆After the compressor has passed the delay protection time, when the cabinet temperature is greater than or equal to the control temperature + temperature return difference, the compressor starts; when the cabinet temperature is less than or equal to the control temperature, the compressor stops.
5.2 Defrost control
◆After the thermostat runs the set defrosting cycle, the defrosting starts and the compressor stops; when the defrosting runs for the set defrosting time, the defrosting stops. If the defrost cycle or time is set to 0, the defrost function will be turned off.
◆Press and hold the "Unlock" button for more than 3 seconds to start manual defrosting, and press the "Unlock" button again for more than 3 seconds to stop defrosting.
◆When F8=0, the cabinet temperature is displayed normally; when F8=1, the cabinet temperature is locked during the defrosting process, and the cabinet temperature display is delayed for 20 minutes or after the cabinet temperature is lower than the control temperature. , Return to normal display; when F8=2, dEF will be displayed during defrosting. After defrosting, the cabinet temperature display will be delayed for 20 minutes or when the cabinet temperature is lower than
the control temperature, the normal display will be restored.
5.3 Lighting control (STC-202)
◆Press the "▲" key to start the lighting, and press the "▲" key again to turn off the lighting.
5.4 Fan control (STC-203)
◆After power on, the fan keeps running and stops when defrosting.
5.5 Alarm control
◆The high and low temperature alarm function is activated only after the compressor has been started once and stopped. When the cabinet temperature is higher than or equal to the set high temperature value F9 and the duration exceeds F12, the high temperature alarm is triggered and the temperature flashes; when the cabinet temperature is lower than the high temperature value F9-F11, the high temperature alarm is released.
◆When the cabinet temperature is lower than or equal to the set low temperature value F10 and the duration exceeds F12, the low temperature alarm is triggered and the temperature flashes; when the cabinet temperature is higher than the low temperature value F10+F11, the low temperature alarm is released.
◆When the cabinet temperature sensor fails, "EE" will be displayed. At this time, the compressor will stop for 30 minutes and run for 15 minutes in timing mode.
5.6 Power on and off control
◆Long press the "▼" key for more than 5 seconds, the display "---" means shutdown, and then press the "▼" key again to turn it on.
6. Selection instructions
MODEL | Defrost output | Lighting output | Fan output |
STC-201 | yes | -- | -- |
STC-202 | Stop defrosting | yes | -- |
STC-203 | Stop defrosting | -- | yes |
7. Wiring diagram:
8. Safety matters
◆The power supply voltage should be consistent with the voltage marked on the machine.
◆Strictly distinguish the three interfaces of power cord, output relay, and sensor, and don't
connect them wrongly! The load must not exceed the contact capacity.
◆Wiring work must be performed with the power supply completely disconnected, and a good
crimp connection between the wire and the terminal should be ensured.
◆It is forbidden to use in high temperature, high humidity, strong electromagnetic interference,
strong corrosive environment.
◆In order to avoid possible interference, it is recommended to keep a proper distance between the
sensor lead and the power cord.
