A. The thermostat is satisfied and the
call for heat is removed.
B. The furnace has been in test mode
continuously for sixty minutes, at
which time the furnace control (IFC)
will exit the test mode and proceed
to normal heating operation as con-
figured. Test mode can not be acti-
vated again unless line voltage
power to the furnace is cycled off
and back on. This is true even if the
dipswitches remain config
ur
ed to the
test settings.
To set the furnace for normal
oper ation:
1. Set the thermostat mode to OFF.
Always allow furnace to complete
the cool down cycle.
2. Switch the 115 volt power to the
furnace OFF. Do not change
set tings with control energized.
3. Remove furnace blower door.
4. Position dipswitches S4-2 and
S4-3 for modulating/single-stage
mode or 2-stage mode.
5. Replace furnace blower door.

2. A calibration cycle will be performed
unless the Test Switches are set for
Test 40%. The LED status indicator
will flash “H” or “h” during the cali -
brat
ion c
ycle.
NOTE: The supply air sensor (field
installed) is required for the furnace cali-
bration cycle. If the air sensor is faulty,
or not properly connected, the fur nace
will not attempt a calibration cycle and
will operate on factory default parame-
ters pre-pro grammed into the micro-
processor.
After calibration, the furnace will then
adjust to the desired Test capacity. This
allows time for the technician t
o check
steady-state operation and evaluate fur-
nace performance.
The furnace will operate at the fixed
Test capacity until one of the following
conditions:
