Chiller Access
Manager
Allows the user to specify the maximum allowed motor current (as a
percentage of FLA). When the motor current reaches this value, the pre-
Standard rotation vanes will not be permitted to open further. If the motor current
rises above this value, the pre-rotation vanes will close to reduce the
current to this value.
Allows the user to specify the current limit value (as a percentage of FLA)
to which the chiller will be limited during the specified pulldown limit
Standard time. This value will override the Motor Current Limit value during this
time period. This function is used to provide energy savings following
chiller startup.
Allows the user to set a period of time for which the pulldown demand
Standard
limit will be in effect after the chiller starts.
