The access levels listed in the previous table begin with the lowest access level and proceed to
the highest access level. Users logged on under higher access levels may perform any actions
permitted by lower access levels. Correct procedure requires that after making necessary setpoint
adjustments, the user returns to the Home screen and logs off. Secure, dynamic access codes are
generated through YORK Chiller Access Manager.
Access code entry attempts
There is a 5-second delay between access code entry attempts. When the user enters an invalid
access code consecutively for the number of times as defined by Max Login Attempts within 5
minutes, the system prevents additional logon attempts for 1 minute. When the user enters a valid
access code, the access level is set to the level that is defined by the access code.
Each successful or failed logon attempt generates an entry in the access log.
Each logoff generates an entry in the access log.

Description
The panel defaults to the lowest access level, which is termed
View. In this mode, the chiller operating values and setpoints can
be observed, but no changes can be made. You can also start
and stop the chiller.
The second access level is termed Standard. The customer can
use this mode to change all the basic setpoints required to
operate the chiller system, for example, leaving chiller water
temperature, adjust local times, demand times, and start and
stop the chiller.

of the chiller. It includes all features of Standard and the ability
to enable and disable the harmonic filter on the VSD, operate
the VSD cooling pump and fans manually, define the condenser
pressure warning threshold, adjust purge mode, and clear
planned maintenance warnings.
