Additional Notes
What is Shared Data?
There are many different models of equipment offered
under the
ComfortNet
and
ComfortBridge
platforms;
however, all these models use only a small handful of
control boards. To make sure each control board can work
inside its intended chassis, we load each board with a
small amount of chassis-specific data when the equipment
is assembled.
When the equipment is installed, this chassis data is copied
over to any other connected communicating equipment and
saved there in case some parts need to be replaced at a
later date. Because this data is shared by other equipment
on the same network, we call it “Shared Data.”
This means if only one part needs to be replaced in a sys-
tem, it’s likely the Shared Data will automatically be loaded
from the existing equipment. However, if multiple parts
need to be replaced all at once and the system loses all the
places where this Shared Data is stored, Shared Data will
need to be reloaded to make sure the freshly installed parts
are compatible with the existing equipment.
When is it Necessary to Load Shared Data?
In short, if a unit reports a d0, d1, or d2 fault code, it will be
necessary to load Shared Data from the card.
One of these fault codes may be generated by a unit after
some parts of the equipment are replaced. After a system
is powered on for the first time, there are two or three plac
-
es where the Shared Data for the entire system is stored.
Shared Data is always stored on the
indoor unit control
board
and the
indoor blower motor
. If the outdoor unit is
a ComfortNet outdoor unit wired in communicating mode
to the indoor unit (i.e. wired using the 1-2-R-C connector),
then Shared Data for the system is also stored on the
outdoor control board.
Shared Data will only need to be replaced if
all
sources of
Shared Data on a system are replaced at the same time.
Loading Shared Data can be avoided by replacing only one
of these parts at a time and powering up the system after
replacing each part.
