Indoor Blower Speeds
1 - When the thermostat is set to "FAN ON," the indoor
blower will run continuously on the field selectable
fan speed ("LOW HEAT" is default) when there is no
cooling or heating demand. See TABLE 21 on page
59 for allowable circulation speeds.
2 - When the EL296DFE is running in the heating mode,
the indoor blower will run on the 'LOW HEAT" or
"HIGH HEAT" speed per demand. See TABLE 20 on
page 59 for allowable heating speeds.
3 - When there is a cooling demand, the indoor blower
will run on the "LOW COOL" or "HIGH COOL" speed
per demand.
Generator Use - Voltage Requirements
The following requirements must be kept in mind when
specifying a generator for use with this equipment:
• The furnace requires 120 volts + 10% (Range: 108
volts to 132 volts).
• The furnace operates at 60 Hz + 5% (Range: 57
Hz to 63 Hz).
• The furnace integrated control requires both po-
larity and proper ground. Both polarity and proper
grounding should be checked before attempting to
operate the furnace on either permanent or tempo-
rary power.
• Generator should have a wave form distortion of
less than 5% THD (total harmonic distortion).

WARNING
Carefully review all configuration information provided.
Failure to properly set DIP switches, jumpers and on-
board links can result in improper operation!
On-Board Link W914 Dehum
On-board link W914, is a clippable connection between
terminals R and DS on the integrated control. W914 must
be cut when the furnace is installed with a thermostat
which features humidity control. If the link is not cut, termi-
nal "DS" will remain energized not allowing the blower to
reduce to low cool speed upon a call for dehumidification.
On-Board Link W951 Heat Pump (R to O)
On-board link W951 is a clippable connection between
terminals R and O on the integrated control. W951 must
be cut when the furnace is installed in applications which
include a heat pump unit and a thermostat which features
dual fuel use. If the link is left intact, terminal "O" will re-
main energized eliminating the HEAT MODE in the heat
pump.
On-Board Link W915 2 Stage Compr (Y1 to Y2)
On-board link W915 is a clippable connection between
terminals Y1 and Y2 on the integrated control. W915 must
be cut if two-stage cooling will be used. If the Y1 to Y2 link
is not cut the outdoor unit will operate in second-stage
cooling only.
Diagnostic Push Button
The diagnostic push button is located adjacent to the sev-
en-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.
