CON/COF — Compressor on time (CON) and o 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” arrow to view the temperature history.
HES — Dierential 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.
