please note if users need to replace a new one, the same spec must be selected,
otherwise it will not be matched with the PCB.
5.6 System protection
5.6.1 Compressor discharge over high protection
When the compressor runs, the system will check discharge temp., if detects it≥
105 C within 5S continuously (parameter c3 as above form displays), the system will
judge it as discharge error, stop compressor and fan motor, show "E03" error code.
When discharge temp. < parameter c3 - 10 °C, it will start fan motor and compressor
(if remains stopped more than 3 minutes).
If this error appears 3 times within 30 minutes, the system will lock on it, the 2
indication LED lights will flash together, and show error code "E03", it can be only
recovered by turning off the power supply.
5.6.2 Low pressure protection
When the compressor runs for 5 minutes, if the system detects low pressure switch
off within 10S continuously, it will enter this protection and show "EL" error code.
When it detects low pressure switch connected, then quites this protection.
If this error appears 3 times within 30 minutes, the system will lock on it, the
indication LED light "Running" will flash, and show error code "EL", it can be only
recovered by turning off the power supply.
5.6.3 Outgoing water temp. sensor failure
If the system detects this temp. sensor in short circuit or disconnected, it will judge
this failure and show "E01" error code, then stop the heat pump for protection.
5.6.4 Ambient temp. sensor failure
If the system detects this temp. sensor in short circuit or disconnected, it will judge
this failure and show "E02" error code, then stop the heat pump for protection.
5.6.5 Discharge temp. sensor failure
If the system detects this temp. sensor in short circuit or disconnected, it will judge
this failure and show "E04" error code, then stop the heat pump for protection.
5.6.6 Ambient temp. over low or over high protection
5.6.6 Ambient temp. over low or over high protection
When the ambient temp. < 8 Centi-degree (C) or < 60 C, the heat pump will stop to
enter protection and dispaly E00 error code.
When ambient temp. ≥ 11C or ≤ 57C (3C difference), the heat pump will restart.
5.6.6 Auto restart
