COMPRESSOR ACTIVE FAULT CODE
AV1001, AV1003 and AV1005 are enumerated values indicating the most significant active fault in each compressor
system of the dehumidifier. The present value for these objects can be decoded as follows:
• 0 – Normal
• 1 – Run/Pumpdown switch in pumpdown position
• 2 – System warmup in progress. Normal for 5 minutes after power-on.
• 3 – Liquid temperature sensor failed
• 4 – Suction temperature sensor failed
• 5 – Compressor current sensor failed
• 6 – Suction pressure transducer failed
• 7 – Discharge pressure transducer failed
• 13 – Low refrigerant pressure detected
• 14 – High compressor motor temperature detected
• 15 – High refrigerant pressure detected
• 50 – Compressor locked out due to 10 faults since last power cycle
COMPRESSOR SYSTEM MODE AND MODE REQUESTED
AV1002, AV1004, AV1006 (Modes) and AV1017, AV1018, AV1019 (Modes Requested) are enumerated values indicating
the operation mode of the corresponding compressor system. The present value for these objects can be decoded
as follows:
• 0 – Compressor Off
• 1 – Air Heating Mode. Recovered heat is being used to heat the air.
• 3 – Pool Water Heating Mode. Recovered heat is being used to heat the water.
• 4 – Air Cooling Mode. Recovered heat is being rejected to an external air or water-cooled condenser.
SENSOR FAULT CODE (XWISENGNLFLTCODE)
AV1023 is an enumerated value indicating a failed sensor. The value for this object is decoded as follows:
• 0 – Normal. No sensors in failure.
• 1 – Return air temperature
• 2 – Return air humidity
• 3 – Supply air temperature
• 4 – Outside air temperature
