CON/COF
— Compressor on time (CON) and off time (COF) with a Probe 1 failure alarm:
These parameters are set at CON 40 minutes and COF 10 minutes. In the event that there is
a Probe 1 failure alarm, the compressor/refrigeration system automatically starts a
predetermined ON/OFF cycle, which is controlled by the CON and the COF parameters.
The customer can adjust these parameters to maintain the desired bottle probe
temperature. During a Probe 1 failure alarm, the bottle probe temperature can be
monitored by pressing the “Up” or “Down” arrows to view the temperature history.
HES
— Differential for Energy Reduction: This parameter is set at 4, which results in a set
point of 58°F during energy reduction. A decrease in this setting will decrease the set
point, and an increase in this feature will increase the set point.
