Run Test Mode:
To enter Run Test Mode, scroll to
mes, then begin the test.
To exit the test mode, momentarily push the Menu key, cycle power to the furnace, or make a valid thermostat
call for capacity or fan.
Sequence of Run Test Mode
-Turns the inducer on in 1
– Turns on the inducer on 2
– Turns the igniter on for 10 seconds
– Turns the circula ng blower on 1 stage compressor speed for 10 seconds
– Turns the circula ng blower on 2 stage compressor speed for 10 seconds (N/A for S9B1)
– Turns the circula ng blower on 1
– Turns on the circula ng blower on 2
The above sequence will repeat two more mes unless the Run Test Mode is exited, see above
Important: The Run Test Mode does not test fire the furnace or bring the outdoor unit on. It is designed to allow
the technician to observe each mode to ensure the IFC, inducer, and circula ng blower are performing as
intended.

e3.1
IDL = Idle, no demand for cooling, heating, or fan
HT1 = Demand for 1
HT2 = Demand for 2
CL1 = Demand for 1
CL2 = Demand for 2
HP1 = Demand for 1
HP2 = Demand for 2
COF = Demand for continuous fan
DFT = Demand for outdoor unit defrost, furnace running in gas heat mode
TP1-9 = Tap selected for airflow
NOTE:
(1) The menu status displayed is solely dependent on the input of 24VAC that is
applied to the low voltage terminal strip.
(2) The status will alternate between the system mode and the airflow request every 2
seconds.
(3) If an error occurs, an E*.* will alternately flash with the system mode and airflow
request. See first example
