In an ALARM situation, the display will display either “WARNING” or “ERROR” with corresponding
warning or error. A “WARNING” will not stop the control process. An “ERROR” will stop the control
process.
MANUAL RESET mode: Pressing ALARM once will silence the audible alarm and clear the on-

minated. The alarm and on-screen message will not clear automatically, even if the system is no
longer in an alarm situation.
AUTO RESET mode: Pressing the ALARM once will silence the audible alarm and clear the on-
screen alarm message. If the alarm situation is still present, the “Alarm/Action Display” will remain
illuminated. If the system leaves and alarm situation, the system will automatically silence the
