Troubleshooting
Cooling Failure
Description of Fault
A CATALYST Cooling Failure Alarm is generated when the CATALYST commands the unit into full cooling and a supply temperature of 65°F or less is not produced after 40 min.
A CATALYST Cooling Failure Alarm will automatically reset when the unit is commanded into full cooling and supply temperature drops below 58°F for 2 consecutive minutes.
Possible Causes
A CATALYST Cooling Fail is typically caused by:
-
Mechanical Issues.
-
Not bypassing the existing economizer controls
-
Unitary safeties.
-
Unit control board restricting cooling command
-
Issues with wiring
-
Incorrect Unit configuration
Troubleshooting
eIQ Platform
-
On the eIQ Platform, navigate to the Settings page of the unit and locate the Soft Switch.
-
Set the Service Switch to the OFF option.
-
Navigate to the Status page and verify the unit is not outputting any commands.
-
Go back to the Settings page and set the Soft Switch to the Cool 1 or 2 Fan 100% (based on the number of cooling stages the unit has) option.
-
Navigate to the Status page of the unit and verify that full cooling is commanded to be on.
-
If the supply temperature drops below 58°F, continue to monitor the unit for 10-15 minutes to verify that the cooling continues to run and does not trip on any unitary safeties.
-
If the supply temperature does not drop below 58°F, a technician will need to investigate the equipment to resolve the issue.
-
Site
-
Access the CATALYST Service Switch typically located in the controls section of the Unit.
-
Set the CATALYST Service Switch to the Unit OFF position and verify the fan and cooling elements are disengaged.
-
Set the CATALYST Service Switch to the Cool 1 or 2 Fan 100% position and verify the cooling command engages.
-
If the Cooling fails to engage:
-
Verify that you have 24 volts AC on the cool command from the CATLYST Green 8 conductor that is landed on the unit’s low voltage terminal.
-
If there is voltage on the cool command wires from the CATALYST green 8 conductor, then the cooling is not functioning due to a mechanical deficiency with the unit. Continue standard mechanical troubleshooting to resolve the issue.
-
If there is no voltage on the cool command wires from the CATALYST green 8 conductor, then contact Transformative Wave for additional troubleshooting support.
