Leaving Chilled Liquid Temperature Cycling
Offset - Restart
Access Level Required: OPERATOR
This value allows the user to specify the Leaving Chilled
Liquid Temperature at which the chiller will restart af-
ter a shutdown on a LEAVIng CHILLED LIQUID
– LOW TEMPERATURE cycling shutdown. This is
done by defining an offset above the Leaving Chilled
Liquid Temperature setpoint. It is programmable over a
range of 0°F to 70°F above the setpoint, to a maximum
restart value of 80°F. The chiller will automatically re-
start when this temperature is reached. This setpoint can
be used to reduce chiller cycling by delaying the chiller
restart until the cooling load has increased.
