Code Diagnostic Codes/Status of Equipment Action Required to Clear and Recover
E290 Ignitor circuit fault - Failed ignitor or triggering
circuitry.
Measure resistance of hot surface ignitor. Replace if open or not within
specifications. 1-hour soft lockout. Clears when flame has been proven
stable.
Table 4. Integrated Diagnostic Codes / Status of Equipment
Diagnostic LED (Figure 4)
The seven-segment diagnostic LED displays operating
status, error codes and other information. Table 4 lists
diagnostic LED codes.
Diagnostic Push Button (Figure 4)
The diagnostic push button is located adjacent to the seven-
segment diagnostic LED. This button is used to enable
the Error Code Recall “E” mode and the Flame Signal “F”
mode. Press the button and hold it to cycle through a menu
of options. Every five seconds a new menu item will be
displayed. When the button is released, the displayed item
will be selected. Once all items in the menu have been
displayed, the menu resumes from the beginning until the
button is released.
Error Code Recall Mode
Select ”E” from the menu to access the most recent 10
error codes. Select “c” from the Error Code Recall menu
to clear all error codes. Button must be pressed a second
time while “c” is flashing to confirm command to delete
codes. Press the button until a solid “≡” is displayed to exit
the Error Code Recall mode.
Flame Signal Mode
Select ”F” from the menu to access the flame signal mode.
The integrated control will display the flame current on
seven-segment LED in in micro amps (uA).
Flame signal mode is exited after any of the following:
• Power is reset
• Pressing and holding push button until 3 horizontal
lines “≡” are displayed
• 10 minutes after entering the flame sense mode.
Integrated Control DIP Switches
Integrated Control DIP Switches
80G2DFE units are equipped with a two-stage integrated
control. This control manages ignition timing, heating
mode fan off delays and indoor blower speeds based on
selections made using the control dip switches and jumpers.
The control includes an internal watchguard feature which
automatically resets the ignition control when it has been
locked out. After one hour of continuous thermostat
demand for heat, the watchguard will break and remake
thermostat demand to the furnace and automatically reset
the control to relight the furnace.
Heating Operation DIP Switch Settings
Switch 1 -- Thermostat Selection -- This unit may be
used with either a single-stage or two-stage thermostat.
The thermostat selection is made using a DIP switch which
must be properly positioned for the particular application.
The DIP switch is factory-positioned for use with a twostage
thermostat. If a single-stage thermostat is to be used, the
DIP switch must be repositioned.
a. Select “OFF” for two-stage heating operation
controlled by a two-stage heating thermostat
(factory setting);
b. Select “ON” for two-stage heating operation
controlled by a single-stage heating thermostat.
This setting provides a timed delay before second-
stage heat is initiated.
Switch 2 --- Second Stage Delay (Used with Single-
Stage Thermostat Only) -- This switch is used to determine
the second stage on delay when a single-stage thermostat
is being used. The switch is factory-set in the OFF position,
which provides a 7-minute delay before second-stage heat
is initiated. If the switch is toggled to the ON position, it
will provide a 12-minute delay before second-stage heat is
initiated. This switch is only activated when the thermostat
selector jumper is positioned for single-stage thermostat
use.
