Hardware ports are reserved on the display module to control the status of
remote dry contacts or remote startup and shutdown signals. The status of
remote dry contacts and remote startup and shutdown signals is started by
default.
Starting a unit over the screen or NMS is valid only when the status of remote
dry contacts or remote start/shutdown signal is started.
If you choose Settings > System Settings > System Control and set Require
password to start or shutdown onsite to Yes, a password is required for
startup or shutdown; if you set Require password to start or shutdown
onsite to No, no password is required for startup or shutdown verification.
Download the Service Expert app from the app store. The app can only run
on Android currently. You must apply for the permission to use the app after
downloading it.
Before starting the unit, check whether there are oil stains on a refrigerant
pipe or a large number of bubbles in the sight glass. If so, the pipe leaks. You
need to rectify the leakage and refill refrigerant onsite to ensure that the unit
runs properly.
