Allows the user to specify the maximum allowed mo-
tor current (as a percentage of FLA). When the motor

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 time. This value will
override the Motor Current Limit value during this time
period. This function is used to provide energy savings
following chiller start-up.
