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
environment
actions, that is, the error message will be sent to each indoor unit and the error
sensor
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 .
