17. Back up running
a. Indoor unit
When the sensor of indoor unit have fault as shown in Table 1, it will automatically enter into back up runningwhile displaying the inspection code. During back up running, the capacity modification control can not beconducted. So the unbalance of capacity will occur. Therefore, the fault sensor must be replaced. When thefault other than that shown in Table 1 occur, such as TC1 x 2 + pressure, TC2 + Pressure, TC1 x 2 + TC2 +TA, etc. Because the reliability has problem, so the indoor unit with fault should be closed. When the indoor unit is under back up running, if the outdoor unit is in manual back up running, the compressormay have fault. So this should be strictly forbidden.

b. Outdoor unit
The sensor used by outdoor unit can be classified as automatic back up running and manual setting back uprunning. (refer to the following page)
