main status display of the chiller will display a message indicating the cause of

cleared. If the chiller has a standing Local or Remote run command, it will start
when the key is pressed.

display associated with it.

start key. Pressing this key allows selection of enter to stop or cancel to remain
running. Enter causes the chiller to perform a soft shutdown and disables the

less an emergency situation exists, in which case the Safety Stop button can be
used.
