Fault Code Reset
To clear the fault code memory, push and hold the “LAST
ERROR” button for more than 5 seconds and less than
10 seconds (the LED will indicate this period by RAPID
GREEN FLASH for 5 seconds to 10 seconds). The LED
will flash three green flashes when the memory has been
cleared.
The ignition control is equipped with a momentary push
button switch that can be used to display on the diagnostic
LED the last five faults detected by the control. The control
must be in Standby Mode (no thermostat inputs) to use the
feature. Depress the push button switch for approximately
2 seconds. Release the switch when the LED is turned
off. The diagnostic LED will then display the flash codes
associated with the last five detected faults. The order of
display is the most recent fault to the least recent fault.
Resetting From Lockout
Furnace lockout results when a furnace is unable to
achieve ignition after three attempts during a single call
for heat. It is characterized by a non-functioning furnace
and a one flash diagnostic LED code. If the furnace is in
“lockout”, it can be reset in any of the following ways.
1. Automatic reset. The integrated control module will
automatically reset itself and attempt to resume
normal operations following a one hour lockout period.
2. Manual power interruption. Interrupt 115 volt power to
the furnace for 1 - 20 seconds.
3. Manual thermostat cycle. Lower the thermostat so
that there is no longer a call for heat then reset to
previous setting. Interrupt thermostat signal to the
furnace for 1 - 20 seconds.
NOTE: If the condition which originally caused the
lockout still exists, the control will return to
lockout. Refer to the
Troubleshooting Chart
for
aid in determining the cause.
