FAULT CODES
12.1
D1
12.1.1
Description
This code displays anytime there is no shared data at the
furnace. The shared data is electronically stored data
that is used to define (among other things) blower op-
eration.
Without the shared data, the furnace cannot
function. Note that shared data may be available even
if there is no memory card attached to the furnace con-
trol. A missing memory card will display fault code ‘’D4”
if shared data is available to the network.
12.1.2
Causes
Typically, the memory card will be missing from the fur-
nace. In most cases, the cause of this fault will be the
loss or disconnection of the original memory card from
the furnace contral (or I.F.C) . When the furnace con-
trol (I.F.C.) is replaced, the memory card must be broken
away, saved and installed int the replacement control.
12.1.3
Solutions
Replace the missing memory card into the connector la-
belled E117 on the furnace control (I.F.C.). If the orig-
inal card cannot be found, a replacement card can be
ordered. Be sure to order the correct memory card for
the furnace. You need the furnace model number and
the serial number. Both can be find on the rating plate,
inside the furance.
NOTE
: Furnace power must be cy-
cled off and then on again after replacing the card or the
shared data will not be read.
12.2
D4
12.2.1
Description
The memory card inserted into the slot at position E117
of the furnace control is corrupt OR there is no memory
card installed at all. However, a valid copy of shared data
for the furnace can be retrieved from the network.
12.2.2
Causes
This fault is displayed when there is no information on the
memory card (blank) or the memory card has corrupted
and cannot be properly used.
12.2.3
Solutions
Remove the memory card and replace with the original
memory card from the furnace or the correct replace-
ment memory card.
Never replace the memory card of
a furnace with a memory card from another furnace
or component (e.g. condenser or air handler). Doing
so could result in improper operation of the blower
which may cause damage to the heat exchanger.
If
the original memory card for the furnace control is avail-
able and working, it must be used. A correct replacement
memory card can be ordered. Be sure to have the fur-
nace model and serial number available when ordering.
12.3
D5
12.3.1
Description
The memory card inserted into the slot at position E117
of the furnace control is not correct for the furnace appli-
cation.
12.3.2
Causes
1. The memory card inserted is from a different type
of furnace.
2. The memory card inserted is from another invalid
unit.
