Local Leaving Chilled
Liquid Temperature -
Setpoint
Operator
This value allows the user to define the Leaving Chilled
Liquid Temperature that is to be maintained by the chiller. It
is programmable over the range of 38.0°F to 70.0°F (water)
or 10.0°F to 70.0°F (brine). If Smart Freeze (see below) is
enabled, the range is 36.0°F to 70.0°F (water).
When the chiller is running, performing capacity control, any
change to the LCHLT setpoint results in a ramp from the old
value to the new value at the programmed LCHLT setpoint
ramp rate.
