Mode
(Cont.)
CCS – Cellar Pre-Chill Set Point: This parameter is set at 52°f, but can be adjusted to a set point
between 45°f - 67°f.
bLL/Act – Compressor O or On for Low (bLL) or High (Act) Temperature Alarm: These parameters
are set at “n”. With this parameter set at “n” the refrigeration system will continue to operate nor-
mally, if there is a High or Low temperature Alarm. To change this parameter, change the setting to
“y”, and the compressor/refrigeration system will shut o during a High or Low temperature Alarm.
Con/Cof – Compressor On time (Con) and O time (Cof) with a Probe 1 failure/Alarm. These pa-
rameters are set at Con 40 min/Cof 10 min. In the event that there is a Probe 1 failure/Alarm, the
compressor/refrigeration system automatically starts a predetermined ON/OFF cycle, which is con-
trolled 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 tempera-
ture can be monitored by pressing the Up or Down arrow to view the High and Low Temperature
History.
Hes – Dierential for Energy Reduction – This parameter is set at 4, which results in a set point of
52°f during the Energy Reduction mode. A decrease in this setting will decrease the set point, and
an increase in this feature will increase the set point.
AUX “AUX” indicates that the condenser fan is running. Pressing the “AUX” button on the control panel
will turn it o.
