Other Control ESIE11-05
58 Functional Description
5. Other Control
5.1 Emergency Operation
If the compressor cannot operate, this control inhibits any applicable compressor or outdoor unit
from operating to perform emergency operation only with the operative compressor or outdoor
unit.
Caution In order to disable the compressor operation due to a failure or else, be sure to do so in
emergency operation mode.
NEVER attempt to disconnect power supply wires from magnetic contactors or else. (Doing so
will operate compressors in combination that disables oil equalization between the
compressors, thus resulting in malfunctions of other normal compressors.)
5.1.1 Restrictions for Emergency Operation
 If the emergency operation is set while the outdoor unit is in operation, the outdoor unit stops
once after pump-down residual operation (a maximum of 5 minutes elapsed).
 Emergency operation is not advised without operable INV compressor.
 Due to emergency operation’s nature, leaving water temperature cannot be guaranteed.
Precize control is not possible.
