Refrigeration, defrost, delay
When the measured value of the room temperature probe is greater than or equal to the upper limit of the temperature, the refrigeration relay is closed and the compressor starts to work. When the measured value of the room temperature probe is less than or equal to the lower temperature limit, the refrigeration relay is disconnected and the compressor stops working. When the defrosting cycle time is up, the refrigeration relay is disconnected, the defrosting relay is pulled in, and defrosting is performed; when the defrosting time is up, the defrosting relay is disconnected and the defrosting is over.
● Quick start: Press the ← key for 3 seconds to start the work quickly after power on.
● Manual defrosting: press the ▲ key for 3 seconds during work to enter the defrosting work.
● Cancel the defrosting function: when the defrosting cycle or defrosting time setting parameter is "0", the defrosting function is canceled.
● Delay: when the compressor, fan, condenser, solenoid valve and defrost relay are on and off, it will lead, lag off and close according to its set parameters. If the set parameter is "0", the delay function will be canceled.
