[SCS Controller - Faults & Alarms](https://support.aofrio.com/iot-hardware-operation-behavior?hsLang=en#scs-controller-faults-alarms) August 25, 2025 # ALr 14 - How the 'Condenser over temp' alarm works ## When the temperature of a cooler condenser is higher than the high temperature limit, the SCS Controller can switch off the compressor to protect the asset and trigger an alarm to alert the site manager or staff. Review the fault logic for the "Condenser over temp" alarm in the following graph: !['Condenser over temp' alarm](https://support.aofrio.com/hs-fs/hubfs/faultlogic_Condenserovertemp_ENG2.jpg?width=670&height=572&name=faultlogic_Condenserovertemp_ENG2.jpg) ### Possible causes and solutions The temperature of a cooler condenser is higher than the high temperature limit. As a result, the SCS Controller switches off the compressor to protect the asset. 1. Check that nothing is blocking the condenser e.g. boxes 2. Then reset by power cycling. If this fault continues to happen, check that the condenser fan is functioning correctly. - [Support for your role](https://support.aofrio.com/support-for-your-role?hsLang=en#main-content) - [Service technician](https://support.aofrio.com/support-for-your-role?hsLang=en#service-technician) -
