should be very close. The value can
also be tracked through the blinking
decimal point on the seven segment
displays at the furnace control
(although with not as much resolu-
tion).
"STATUS 2" menu – This menu also
gives information about the status of
certain furnace components and fea-
tures.
1. MODE – Indicates the current state
of operation of the furnace. The
possibilities are listed below:
a. MOD HEAT – Heat operation
b. AC – Air conditioning operation.
c. FAN ONLY – Continuous fan
operation.
d. HP – Heat-pump operation.
2. MOTOR MFGR – Indicates the
manufacturer of the main air-circu-
lating blower motor. At the time of
this publication there are two possi-
bilities; RGBLT for Regal Beloit (for-
merly GE) and EMERSON.
3. MOTOR RPM – Indicates the RPM
of the main circulating air blower.
4. MAXIMUM CFM – Indicates the
maximum CFM that the main circu-
lating air blower can deliver.
5. BLOWER CFM – Indicates the out-
put of airflow in CFM of the main cir-
culating air blower.
6. HUM OUTPUT – Indicates when the
humidifier output is turned on.
7. EAC OUTPUT – Indicates when the
electronic air cleaner output is
turned on.
"2 WK HIST" menu – This menu gives
information about the number of cycles
and the amount of time spent in various
modes of operation over the last 14
days.
NOTE: For both 2 WK & LIFE HIST, the
value saved prior to power loss may not
include information from the last hour of
operation. This is because the informa-
tion is only stored once every hour.
1. MOD HT HRS – Indicates the num-
ber of hours of operation of gas
heating operation rate in the last 14
days.
2. MOD HT CYCLS – Indicates the
number of cycles of operation (i.e.:
the number of times it turned on and
off) of gas heat operation in the last
14 days.
3. BLOWER HRS – Indicates the num-
ber of hours of continuous fan oper-
ation in the last 14 days.
4. BLOWER CYCLS – Indicates the
number of cycles of operation (i.e.:
the number of times it turned on
and off) of the continuous fan oper-
ation in the last 14 days.
"LIFE HIST" menu – This menu gives
information about the number of cycles
and the amount of time spent in various
modes of operation over the life of the
furnace.
NOTE: For both 2 WK & LIFE HIST.,
the value saved prior to power loss
may not include information from the
last hour of operation. This is because
the information is only stored once
every hour.
1. TOTAL DAYS PWRD – Indicates
the total number of days that the
furnace has been powered. This
number is not affected by any ther-
mostat operation.
2. MOD HT HRS – Indicates the num-
ber of hours of operation of gas
heating operation over the life of
the furnace.
3. MOD HT CYCLS – Indicates the
number of cycles of operation (i.e.:
the number of times it turned on
and off) of gas heat operation over
the life of the furnace.
4. BLOWER HRS – Indicates the
number of hours of continuous fan
operation over the life of the fur-
nace.
5. BLOWER CYCLS – Indicates the
number of cycles of operation (i.e.:
the number of times it turned on
and off) of the continuous fan oper-
ation over the life of the furnace.
"FAULT HISTORY" menu – This menu
gives information about the six most
recent faults experienced by the fur-
nace. The most recent fault is dis-
played upon entering the menu. Three
seconds later the text "DAYS" is dis-
played followed by a number. The
number indicates the number of days
since that fault was experienced.
The faults can be viewed in order of
occurrence. Pressing the down arrow
key once will permit viewing of the next
most recent fault. Pressing the key
again will display the second most
recent fault and so on.
If no fault present in the memory, the
text "NO FAULT" and "DAYS 0" will be
displayed. It is possible that there will
be less than six faults stored (if less
than six faults have occurred since
installation or clearing of faults). In this
case, the existing faults will be dis-
played in the order of occurrence and
the remaining faults will be displayed
as "NO FAULT" and "DAYS 0".
The final item in this menu is
"CLEAR FAULTS". The options are
"yES" and "no". This item permits
the faults to be cleared so all six
positions will display "NO FAULT"
and "DAYS 0".
When faults are cleared, the right
seven segment display on the fur-
nace control will flash the upper and
lower horizontal bars once.
Note that the "FAULT HISTORY"
only accumulates days when power
is applied to the furnace control
board. For example, if a fault actu-
ally occurred ten days ago and the
furnace was not powered for two of
the ten days, the fault will be dis-
played with the text "DAYS 8"
instead of "DAYS 10" is displayed to
indicate the number of days since
the fault occurred.
"UNIT INFO" menu – This menu
gives information about the furnace.
1. MODEL NUMBER (MN)
2. SERIAL NUMBER (SN)
3. SOFTWARE VERS.
"SETUP" menu – This menu permits
the field adjustment of certain para-
meters of the furnace. The selected
values will be saved in memory
even when power is lost and
restored. The procedure for making
changes in the furnace setup menu
will vary depending on the thermo-
stat or service tool that is used. To
enter, navigate, make changes to or
exit the furnace "SETUP" menu
using a communicating thermostat,
see the installation and operation
instructions for that thermostat.
1. HEAT RISE ADJ* – The value
of the heat rise can be changed
to reflect the comfort of the
homeowner. The value can be
changed between "NOM +10"
(nominal or mid temperature rise
plus 10 degrees F) and "NOM"
(nominal or mid temperature
rise). Additional adjustment can
be to low and high heating rates
(and all points between) at the
"MIN HEAT ADJ" and "MAX
HEAT ADJ" menu items in
items 2 and 3 below.
The temperature rise values list-
ed are for reference only. The
actual measured temperature
rise may be different than
expected by several degrees.
The default factory setting for
the heat rise is "NOM +10".
*ALL TEMPERATURES CAN
BE DISPLAYED ONLY IN
FAHRENHEIT VALUES
