Why does my S&A CWFL-3000BT display an ultra-high temperature alarm (E05 or E07)?

An ultra-high temperature alarm (E05 or E07) on your S&A Chiller can be triggered by several factors: * A blocked dust gauze preventing proper thermolysis. Regularly unpick and wash the dust gauze. * Poor ventilation. Ensure smooth ventilation for the air outlet and inlet. * Unstable or extremely low voltage. Improve the power supply circuit or use a voltage regulator. * Improper thermostat settings. Reset the controlling parameters or restore factory settings. * Frequent power switching. Allow sufficient time for refrigeration (more than 5 minutes). * Excessive heat load. Reduce the heat load or consider a model with larger cooling capacity.
