Page 2: Overview
Troubleshooting Guide CN-IC1-09 i-Controller REV.200 Alarms (Troubleshooting) Title Overview The following document is used to troubleshoot controller alarms. When an i-Controller alarm exists, you can refer to this document to understand the condition. Clogged Filter Notice The clogged filter notice is generated when the filters in the unit become blocked and possibly need to be replaced. When a clogged filter notice is generated, “NOTICE”...
Page 3: Co 2 Notice (If Equipped)
Troubleshooting Guide CN-IC1-09 i-Controller REV.200 Alarms (Troubleshooting) Title Notice (if equipped) The CO notice is generated when the CO level in the space is too high. When a high CO level is detected, “Hi LvL” will be displayed next to “CO2 Level Status” on the Alarms screen.
Page 4: Compressor High Discharge Trip Alarm
Troubleshooting Guide CN-IC1-09 i-Controller REV.200 Alarms (Troubleshooting) Title Compressor High Discharge Trip Alarm The high discharge trip is generated when a high discharge pressure condition is present and compressor proof fails. When a high discharge trip alarm is generated, “ALARM” will be displayed next to “COMP High Dis Trip” on the Alarms screen.
Page 5: Compressor Proof Alarm
Troubleshooting Guide CN-IC1-09 i-Controller REV.200 Alarms (Troubleshooting) Title Compressor Proof Alarm The compressor proof alarm is generated when a specific compressor is not running when enabled by the controller. If a digital compressor is at 50% capacity and the discharge pressure minus suction pressure is less than 20psi, a compressor proof alarm will be generated.
Page 6: Drain Pan Overflow Alarm
Troubleshooting Guide CN-IC1-09 i-Controller REV.200 Alarms (Troubleshooting) Title Drain Pan Overflow Alarm The drain pan overflow alarm is generated when the drain pan float switch detects an elevated level of water in the condensate drain pan. When an overflow alarm is generated, “ALARM” will be displayed next to “Overflow Status” on the Alarms screen.
Page 7: Fan Fail Alarm
Troubleshooting Guide CN-IC1-09 i-Controller REV.200 Alarms (Troubleshooting) Title Fan Fail Alarm The fan fail alarm is generated when a fan fails to start for more than 10-minutes when enabled by the controller. When a fan fail alarm is generated, “ALARM” will be displayed next to “Fan Status” on the Alarms screen.
Page 8: Heat Alarm
Troubleshooting Guide CN-IC1-09 i-Controller REV.200 Alarms (Troubleshooting) Title Heat Alarm The heat status alarm is generated after 15-minutes if the supply temperature has not increased by at least 5˚F when heat mode has been enabled. When a heat status alarm is generated, “ALARM” will be displayed next to “Heat Status” on the Alarms screen.
Page 9: Heat Reclaim Notice (If Equipped)
Troubleshooting Guide CN-IC1-09 i-Controller REV.200 Alarms (Troubleshooting) Title Heat Reclaim Notice (if equipped) A heat reclaim or reheat notice is generated when the supply temperature has not increased at least 5˚F after heat reclaim or reheat has been enabled for 15-minutes. When a heat reclaim notice is generated, “YES” will be displayed next to “Reclaim Proof”...
Page 10: High Discharge Pressure Alarm
Troubleshooting Guide CN-IC1-09 i-Controller REV.200 Alarms (Troubleshooting) Title High Discharge Pressure Alarm The high discharge pressure alarm is generated when the discharge pressure increases above 500psi for 5-minutes while a compressor is enabled throughout dehumidification or cooling mode. In the event of controller failure, a mechanical cut- out will occur at 600 psi.
Page 11: High Suction Pressure Alarm
Troubleshooting Guide CN-IC1-09 i-Controller REV.200 Alarms (Troubleshooting) Title High Suction Pressure Alarm For a digital compressor, the high suction pressure alarm is generated when the suction pressure increases above 140psi for 10-minutes when a compressor is enabled during dehumidification or 170psi in cooling mode. For a fixed compressor the high suction pressure alarm is generated with the suction pressure increases above 160psi and reset when the pressure decreases below 150psi.
Page 12: Low Suction Pressure Alarm
Troubleshooting Guide CN-IC1-09 i-Controller REV.200 Alarms (Troubleshooting) Title Low Suction Pressure Alarm The low suction pressure alarm is generated when the suction pressure decreases below 80psi throughout dehumidification or cooling modes for more than 10-minutes. In the event of controller failure, a mechanical cut-out will occur at 60 psi.
Page 13: Phase Loss Alarm
Troubleshooting Guide CN-IC1-09 i-Controller REV.200 Alarms (Troubleshooting) Title Phase Loss Alarm The phase loss alarm is generated when the unit is not receiving proper power and to protect the motors and compressors from voltage imbalance, over/under voltage or improper electrical phasing for 30-seconds. When a phase loss alarm is generated, “ALARM”...
Page 14: Refrigerant Leak Notice (If Equipped)
Troubleshooting Guide CN-IC1-09 i-Controller REV.200 Alarms (Troubleshooting) Title Refrigerant Leak Notice (if equipped) The refrigerant leak notice is generated if a refrigeration leak in the space is detected by the leak detection system and the leak signal via digital closure is sent to the i-Controller. Once the signal is received by the i-Controller, the OAD of the Flō...
Page 15: Sensor Failure Alarm
Troubleshooting Guide CN-IC1-09 i-Controller REV.200 Alarms (Troubleshooting) Title Sensor Failure Alarm The sensor failure alarm is generated when one or more of the temperature, transducer, humidity or CO2* sensors are faulty. When a sensor failure alarm is generated, “FAIL” will be displayed next to the corresponding sensor on the Sensor Status screen.
Page 16: Smoke Detector Alarm
Troubleshooting Guide CN-IC1-09 i-Controller REV.200 Alarms (Troubleshooting) Title Smoke Detector Alarm This smoke detector alarm is generated when smoke is detected in the unit or air stream. When the smoke detector alarm is generated, “ALARM” will be displayed next to “Smoke Det. Status” on the Alarms screen.
