trol or a valid replacement
memory card ordered from
ProStock.
or
2. by attaching the furnace con-
trol to a communicating net-
work (e.g. a condenser and
thermostat) which was previ-
ously connected to (and
operating with) a valid fur-
nace control with valid fur-
nace shared data.
Regardless, the memory card
of a replacement control can-
not be programmed or repro-
grammed in the field with fur-
nace shared data and will
always remain blank. In fact,
this card does not even con-
tain the electronic compo-
nents necessary to turn it into
a valid memory card.
V. Replacement memory cards
with the appropriate furnace
shared data for any given
model can be ordered from
Pro-Stock. In the event that the
original memory card is lost, the
original furnace control has
been replaced and there is no
furnace shared data on the net-
work (or the furnace is not part
of a communicating network
(i.e.: is not connected to a com-
municating condenser and ther-
mostat)), the replacement
memory card must be ordered
and installed into the connector
at J15 to give the furnace valid
furnace shared data. The fur-
nace will not operate properly
without the correct furnace
shared data. When no furnace
shared data is present (either at
the memory card or on the net-
work) a "d1" (NO SHARED
DATA) fault code will be dis-
played at both the thermostat
active fault screen and at the
furnace control (I.F.C.) seven-
segment displays. Also, the
homeowner will be alerted via
the communicating thermostat
with either a CHECK SYSTEM
or CHECK FURNACE error
message displayed on the main
screen.
If the original memory card is
lost, it should be replaced even
if there is valid furnace shared
data on the network. The valid
furnace shared data on the net-
work should only be considered
as a backup to the memory
card.

b. If valid furnace shared data is
available from the network and no
memory card is present, a "d4"
(MEM CARD INVALID) fault is
displayed at the communicating
thermostat active fault screen and
at the furnace seven-segment dis-
plays when in standby mode only
(see fault code priority list). The
homeowner is not alerted (level 1
fault).
c. If no furnace shared data is pre-
sent on the network and a memo-
ry card is either not present or the
shared data on the memory card
is not valid, a "d1" (NO SHARED
DATA) fault is displayed at both
the communicating thermostat
active fault screen and at the fur-
nace seven-segment displays
provided a higher priority fault
code is not also present (in which
case the higher priority fault is
displayed) (see fault code priority
list). The homeowner is alerted
via the communicating thermostat
(level 2 fault).
d. If furnace shared data from the
memory card is not valid or is not
present and shared data from
network can be used, the appro-
priate fault (d4, d5, d6, d7 or d8 –
see fault codes in this manual) is
displayed at the communicating
thermostat active fault screen and
at the furnace seven-segment dis-
plays during standby mode only.
The homeowner is not alerted
(level 1 fault).
2. If o o n n e e m m e e m m o o r r y y c c a a r r d d p p r r e e s s e e n n t t
(attached to IFC o o r r inserted in J15 of
the IFC), furnace shared data from
the memory card (if valid) will be
used to write (or re-write) the net-
work furnace shared data and fur-
nace shared data from card will be
used. If the data on that card is not
valid,:
a. If furnace shared data on the
memory card
I. is corrupt or invalid ("d4" –
MEM CARD INVALID"),
and/or
II. is for another component or
different furnace series ("d5" –
CARD-HARD CNFLCT),
and/or
III. does not match the horsepow-
er of the attached motor ("d6"-
BLWR HP CNFLCT),
and/or
IV. does not support the motor
manufacturer of the motor pre-
sent ("d7" - BLWR MFG
CNFLCT),
and/or
V. is from an older furnace
and is missing critical
newer furnace shared data
("d8" - OLD SHARED
DATA),
furnace shared data from
the network (if valid) is used
to control the furnace (see
description of "network"
under "If n n o o m m e e m m o o r r y y c c a a r r d d
p p r r e e s s e e n n t t " (item 1 above)).
Furnace shared data on the
network will not be written
or re-written from the mem-
ory card. If the furnace
shared data on the network
is valid, the appropriate
fault for the memory card
will be displayed at the
active fault screen of the
communicating thermostat
and at the furnace seven-
segment displays when in
standby mode only (see
fault code priority list). The
homeowner will not be
alerted (level 1 fault).
b. If neither the furnace shared
data on the memory card is
valid nor the furnace shared
data on the network is valid,
the fault code status is elevat-
ed. The homeowner is alerted
via the communicating thermo-
stat (level 2 fault) and the fault
code d1 (NO VALID SHARED
DATA) is displayed at the com-
municating thermostat active
fault screen and at the furnace
seven-segment displays pro-
vided a higher priority fault is
not also present (in which
case the higher priority fault is
displayed) (see fault code pri-
ority list).
c. If no furnace shared data is
available on either the memory
card or the network, the fault
code "d1" (NO SHARED
DATA) is displayed at the com-
municating thermostat active
fault screen and at the furnace
seven-segment displays pro-
vided a higher priority fault is
not also present (in which
case the higher priority fault is
displayed) (see fault code pri-
ority list). The homeowner is
alerted via the communicating
thermostat (level 2 fault).
Furnace shared data on the
network will not be written or
re-written from the memory
card.
