Product overview and functions
STC-8080A+ is a general-purpose single-sensor temperature controller, with functions such as refrigeration, defrosting, and temperature over-limit alarm. The compressor protection delays curing for 3 minutes. After the sensor fails, it starts and stops according to the curing ratio. It is suitable for cold storage. Refrigeration industries such as refrigerated trucks.

Key operation instructions
View parameter settings
◊Press and immediately release the ▲ key to display the set temperature upper limit; press and immediately release the ▼ key to display the set temperature lower limit: press and immediately release the Rst key to display the set defrost cycle : Press and immediately release the Rst key to display the set defrosting time. After 2 seconds, it returns to the normal temperature display state.
♦Modify parameter setting value
Press the Set key for more than 3 seconds to enter the parameter modification mode, the last adjusted menu item after power-on is displayed, and the colleague parameter modification mode indicator light is on.
Press the ▲ key or the ▼ key to scroll up or down the menu item, and press the Set key to display the parameter setting value of the current menu.
Press and hold the SET key, and then press the ▲ key or ▼ key to adjust the parameter setting value of the current menu. At the same time, press and hold the SET key and the ▲ key for more than one second to quickly increase the parameter setting value of the current menu, and press at the same time Hold down the SET key and the ▼ key for more than one second to quickly lower the current menu parameter setting value.
Press and hold the RET button or there is no button operation within 30 seconds to save the parameter modification and return to the normal temperature display state.
Manual defrost
Manual defrosting function is allowed when the set value of defrosting time is not 0.
Non-defrosting time Press and hold the ▼ key for more than 3 seconds to start manual defrosting
When defrosting, press and hold the ▼ key for more than 3 seconds to stop defrosting manually
Restore parameter settings
When the machine is powered on, first check whether the parameter settings are correct. If an error is detected, E1 will be displayed and the buzzer will sound. Press and hold the SET key at this time to restore the default parameter settings and work normally. It is recommended to reset the parameters at this time
Control output
compressor
When the storage temperature is higher than the set upper temperature limit, the compressor will be turned on, and when the temperature is lower than the set lower temperature limit, the compressor will be turned off. After the storage temperature sensor fails, the compressor will run at a ratio of 15 minutes and 30 minutes after being powered on. Compressor that runs for 3 minutes after shutting down
The protection time allows the compressor to be turned on again.
change
When the machine has completed the set defrosting cycle or when the machine is not defrosting, press and hold the ▼ key for more than 3 seconds to start defrosting. During the defrosting period, refrigeration output is prohibited. Defrost, restart the defrost cycle after the machine is energized or after the defrost is over. When either the defrost cycle or defrost time is set to 0, the timing defrost function will be cancelled, but manual defrost is allowed when the defrost time is not 0. Frost.
Call the police
When the temperature overrun deviation is not 0, the storage temperature is higher than the set temperature upper limit + temperature overrun deviation or lower than the set temperature lower limit-the temperature overrun alarm occurs when the temperature overrun deviation, and the current temperature is flashing and displayed The buzzer sounds and the alarm is released when the temperature drops to the normal temperature range.
E1 flashes and the buzzer sounds when the memory is faulty, E2 flashes and the buzzer sounds when the sensor is faulty, and the storage temperature is higher than 99℃
And it shows HH when it is lower than 120℃. When alarming, press any key to manually silence the sound, but the alarm display state will not be changed.
