The components are as following:
5.2、Compressor Speed Setting:
The compressor’s speed could be adjusted in range 2,000rpm~3,500rpm by adjusting the resistor of presetting speed:

Controller calibrator to the applied voltage automatically. When the battery voltage is lower than 17VDC, the controller consider it is working in a 12VDC system. When the voltage is higher than 17 VDC, the controller consider it is working in a 24VDC system. If a 220KΩ resistor is connected between “C” and “T”, the operating voltage range could be extended between 9.6V~31.5V, which means ACV20DC is very suitable for photovoltaic solar power application.
5.4、Error Indication
If the start failed, the controller will attempt restarting every 60s until a successful start is achieved. The following Table shows the Error Type and reason.
Table 5 Error Indications:
Number of flashes | Error Type |
1 | Battery protection cut-out
(Battery voltage is outside the setting range shown in Table 4) |
2 | Fan over-current cut-out
(The operating current of cooling fan is more than 1A) |
3 | Motor start error
(The rotor is blocked or the system pressure is too high) |
4 | Minimum motor speed error
(If the refrigeration system is too heavily loaded, the motor speed is lower than 1,850 rpm) |
5 | Thermal cut-out of controller
(If the refrigeration system has been too heavily loaded, or if the ambient temperature is high than 55℃, the controller will run too hot) |
