WhisperKool 2500 manual Troubleshooting Alarm Codes, Cont, Button, Normal Functions, Cpsm, Mode

Button	Normal Functions	cont.
CPSM	• Fof - Humidity Management Enhancement: This parameter is normally set at 1. This pa-
Mode	rameter should not be adjusted, as it simply provides an OFF cycle time for the fan, during
(Cont.)	the compressor OFF cycle. However, the parameter is located within the CPSM as a conve-
	nience to the customer, should it need to be adjusted.
	• 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 Off or On for Low (bLL) or High (Act) Temperature Alarm: These pa-
	rameters are set at “n”. With this parameter set at “n” the refrigeration system will continue
	to operate normally, 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 off	during a
	High or Low temperature Alarm.
	• Con/Cof – Compressor On time (Con) and Off time (Cof) with a Probe 1 failure/Alarm. These
	parameters 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 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 High and Low Temperature History.
	• Hes – Differential for Energy Reduction – This parameter is set at 4, which results in a set
	point of 58°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 the unit is in its anti-frost mode. This means the evaporator temp has reached
	a low temp of 26° and has sustained that temp for a period of five minutes. ( The compres-
	sor and condenser fans will turn off, but the evaporator fans will continue to run. Once the
	temperature of the evaporator gets back up to 40°, the “AUX” light will deactivate and the
	system will revert back to normal operating conditions.)

TROUBLESHOOTING ALARM CODES

Alarm Codes	Cause	Solution
“P1”	Bottle probe failure	Replace Bottle Probe
“P1”	Bottle probe Disconnected	Reconnect Bottle Probe
“P2”	Evaporator Probe Failure	Replace Evaporator Probe
“HA”	Max Bottle Probe Temp Alarm	Check the set point, lower if needed
		Check the door for a good seal
		Check for sufficient insulation, re-insulate if needed
“LA”	Minimum Bottle Probe Temp	Check the set point, raise if needed
	Alarm
“EA”	External Alarm	Check the display to see which alarm code is causing the alarm.
		Then located the solution and repair.
“POF”	Keypad locked	Hold “Up” and “Down” buttons for 3 to 5 seconds to disable,
		“PON” should appear once key pad is unlocked
