EXPLANATION OF THE ADJUSTABLE STATES

IDU error = the indoor unit is malfunctioning, the A/C shuts down completely and an error message
appears on the indoor unit display. Call a qualified service technician for troubleshooting. A manual
restart of the A/C by disconnecting it from the power supply is required after the error has been
fixed.
ODU error = the outdoor unit is malfunctioning, the A/C shuts down completely and an error
message appears on the indoor unit display. Call a qualified service technician for troubleshooting. A
manual restart of the A/C by disconnecting it from the power supply is required after the error has
been fixed.
IDU+ODU error = aggregated error = the outdoor and/or indoor unit is malfunctioning, the A/C shuts
down completely and an error message appears on the indoor unit display. Call a qualified service
technician for troubleshooting. A manual restart of the A/C by disconnecting it from the power
supply is required after the error has been fixed. Excludes the outdoor unit general error (ODU
general error), includes the communication error (E6).
Limitation = some of the monitored values (temperature, pressure, current, voltage) is outside the
permissible value range and therefore the A/C performance is limited by limiting the compressor
frequency or shutting it down. This limitation does not appear on the indoor unit display. After the
causes of the limitation have disappeared (e.g. by decreasing the compressor discharge
temperature), the unit can continue to operate without limitation. In some cases, if the limitation
occurs repeatedly or lasts for a certain period of time, the A/C may be shut down for one of the
errors, which will then appears on the indoor unit display. Call a qualified service technician to
determine the cause of the limitation and, if necessary, to fix the fault. The service technician can use
the SDT-ASH diagnostic module to more accurately identify the cause of the limitation.
ODU general error = outdoor unit has a problem or protects itself from a fault. The compressor
frequency and the A/C output power are reduced or the A/C shuts down completely. The error
message may or may not appear on the IDU display. It also includes all outdoor unit errors (ODU
error). Call a qualified service technician to determine the cause of the limitation and, if necessary, to
fix the fault. The service technician can use the SDT-ASH diagnostic module to more accurately
identify the cause of the general error. You can also contact the Sinclair Technical Support.
A/C is on = the relay is closed when the A/C is switched on.
Compressor = the relay is closed when the compressor is running
Cooling = the relay is closed when the cooling mode is activated.
