Error warning If the unit experiences an error in any of the functions, a warning will appear in the display.
The error warnings will correspond to any of the following:
Menu Item Description
LP Error The LP error is activated when the temperature dierence between the
condenser and evaporator coil is less than 5°C (Tc – Te <5°C). This is in-
dicative of a loss of refrigerant in the circuit, but the LP Error can also be
activated by other faults such as HP switch trip, compressor malfunction or
TEV malfunction. See fault nding section for further information. If the LP
Error is activated the dehumidier is stopped and blocked from automatic
operation pending user intervention. After troubleshooting the cause of
the LP Error the unit can be restarted by pressing the “ON/OFF” button in
the touch display.
HP Error When condenser coil temperature exceeds the software HP setting the HP
Error will be activated. The HP Error is congured to disable the dehumidi-
er before the pressure in the refrigeration circuit exceeds the trip limit of
the mechanical HP switch. Once the HP Error is active the unit stops and
goes into pause state to cool down and the HP counter is incremented.
When the condenser coil temperature has decreased to more than 10°C
below the software HP setting the HP Error is reset automatically. The de-
humidier will be able to resume operation again once the cool down timer
has expired.
If the HP Error occurs 5 consecutive times the dehumidier is stopped and
blocked from automatic operation pending user intervention. After trouble
shooting the cause of the HP Error the HP counter is reset by the user by
pressing the “ON/OFF” button in the touch display. Remember to verify if
the mechanical HP switch has also been tripped.
Low Tempr. Ambient temperature less than specied operating range. Dehumidier will
not run until ambient temperature increases.
High Tempr. Ambient temperature higher than specied operating range. Dehumidifer
will not run until ambient temperature decreases.
C. Sensor Condenser coil temperature sensor malfunction / sensor value out of range.
Short circuit or wire break / bad connection.
E. Sensor Evaporator coil temperature sensor malfunction / sensor value out of range.
Short circuit or wire break / bad connection.
RH Sensor RH sensor malfunction. Fault on I2C communication to controller.
