•
Then, to reset, hold the button down for 15
seconds until the red light turns off and the yellow
LED turns on. Observe at least one full control
sequence of operation from startup to shutdown.
Simulate a flame failure lockout by following the
procedure (within this manual). If the operation is
erratic, or not to specifications, then replace the
control. Always verify the control functions
according to all specifications before leaving the
installation site.
DISABLE FUNCTION
•
Any time the burner is running, press and hold the
reset button to disable the burner. The burner will
remain off as long as the button is held.

Flame Quality Monitor
This control is trained to recognize and remember a
good flame based on initial burner set up. Control
then monitors the flame via the CAD cell signal for
deviation in the combustion characteristics of the
burner. If the control senses a deviation on the
high side or on the low side from the original set up
condition for three consecutive cycles, it will trigger
an alarm circuit which can be tied to an audible local
device to signal the home owner or into the home
security system. Upon being notified of the alarm,
the security agency will notify the dealer of choice
based upon information supplied by the home owner.
The system will also be capable of being connected
to a phone line that will contact the dealer directly
with the alarm. This alarm will typically sound 3 to
5 days prior to the primary control going into lockout
giving the service agency a prior notice before a
sooting condition or other failure can occur resulting
in untold savings. This monitor system is available
through your local distributor under the Honeywell
Part #QS7100F.

If the control locks out three times without a
satisfied call for heat, or due to other significant
events such as a relay contact weld, the Lockout
becomes
restricted
in order to prevent repetitious
resetting by the homeowner.
Electronic Blower Control Interface
This furnace is equipped with an Electronic Blower
Control Interface, which through its set points
determines what the blower does with the 24 VAC
inputs from the home thermostat.
There are dip switches that control the ECM motor for:
1. Heating Airflow
2. Cooling Airflow
3. Heating On/Off Delay
4. A
+
10% adjustment for heating airflows.
(See to Figure 5 for the location of these switches.)
The Electronic Blower Control Interface also
performs the additional functions of having a
diagnostic light, which indicates a safety limit is open,
and also has a relay which isolates the T-T signal
from the oil primary control.
Required 24 VAC inputs for various functions:
Continuous Blower: “R” to “G”
Heating with Oil Furnace: “R” to “W”
Cooling Single Stage: “R” to “G”, “Y1” & “Y2”
Cooling Two-Stage, Part Load: “R” to “G” & “Y1”
Cooling Two-Stage, Full Load: “R” to “G”, “Y1” & “Y2”
Heat Pump Single Stage: “R” to “G”, “Y1”, “Y2” & “O”
Heat Pump Two-Stage, Part Load: “R” to “G”, “Y1” & “O”
Heat Pump Two-Stage, Full Load: “R” to “G”, “Y1”, “Y2” & “O”
RESETTING FROM RESTRICTED LOCKOUT
CAUTION
Before resetting the control from restricted
lockout state, troubleshoot the heating
system for the root cause(s) of lockout and
make necessary repairs or adjustment to
ensure a safe start condition.
