Test for 30 seconds successively to check if the temperature
sensor is disconnected. If yes, alarm will be sent; otherwise no
processing will be made. If the controller of outdoor unit detects
failure of outdoor sensor under open circuit, short circuit and
excess of test value, the outdoor unit will execute the following
default actions, that is, the error message will be sent to each
indoor unit and the error code will be displayed via error indicator
or wired controller. When the outdoor ambient temperature is
lower than -5
℃, the disconnection failure of outdoor inlet, middle
and exit sensors in shield room will be processed as under -30
℃.
