ERRORS AND ALARMS EXPLANATION
HU-SOUTHWEST-1480 GAS-FIRED HUMIDAIRE UNIT
(FOR SOFTWARE VERSIONS 2.0 AND LATER)
PRELIMINARIES
-- ERRORS will cause the Humidaire Unit to automatically shut
down. ALARMS will permit the unit to continue operation but warn of conditions which
may cause a shutdown if left unattended. In each case, a brief description of the ERROR
or ALARM will be shown on the color touch screen along with an abbreviated remedy.
The display will continue to show the ALARM or ERROR until the OK button is pressed.
Only one ALARM or ERROR condition is displayed at a time. The oldest
unacknowledged ALARM condition is shown even if the Humidaire shuts down due to an
ERROR. Pressing the OK button will show consecutive ALARM conditions leading up to
the shutdown ERROR.
EXAMPLE: The flame electrode is fouled. This prevents the burner from having a
flame signal. ALARM code 146 (Burner failed to ignite) is displayed and the status light
flashes. While this is occurring, the burner is automatically restarting itself (three times
max) attempting to light. The burner shuts itself down on ERROR code 144 (Excessive
flame failures) after 3 unsuccessful tries. The display continues to show ALARM code
146 although the status light is still flashing and the burner is shut down due to an
ERROR. Press OK to clear each ALARM code and then to clear ERROR code 144.
After ERROR code 144 is cleared, the operator can attempt to restart the burner.
