The Zy-8068 is widely used in generator sets, industrial power supply systems, and precision electronic equipment to maintain stable output voltage. Its manual is critical for:
Before diving into the manual, it is important to identify your device. The Zy-8068 model number most commonly appears on:
Because the Zy-8068 is frequently a white-label product (manufactured by one factory and sold under dozens of different "brands" on Amazon, eBay, or Alibaba), the Zy-8068 Manual PDF is often generic. This means the same PDF works for ten different looking devices.
| Code | Function | Description | Range / Setting |
| :--- | :--- | :--- | :--- |
| HC | Mode Selection | Determines if the device turns ON to Heat or Cool. | H = Heating Mode (Turns ON when temp drops below setpoint).
C = Cooling Mode (Turns ON when temp rises above setpoint). |
| d | Hysteresis (Difference) | The range of temperature change allowed before the output switches. | 0.1°C ~ 30°C.
Example: If Set Temp is 25°C and Hysteresis is 2°C, the heater turns ON at 23°C and OFF at 25°C. |
| P | Temperature Calibration | Corrects sensor reading errors. | -10.0°C ~ +10.0°C.
Example: If sensor reads 26°C but actual is 25°C, set P to -1.0. |
| CA | Delay Protection | Delay time before the compressor (Cooling mode) starts again. | 0 ~ 10 Minutes.
Prevents short-cycling compressors. |
| AH | High Temp Alarm | Sets the temperature threshold for the high-temperature alarm. | 0°C ~ 110°C. (Set to 0 to disable). |
| AL | Low Temp Alarm | Sets the temperature threshold for the low-temperature alarm. | -50°C ~ 0°C. (Set to 0 to disable). |
