Components
7.7.3 Memory Card
•
The memory card stores all unit information.
•
The unit information is called model data.
•
The model data is all the information needed for
proper unit operation of that specific model.
7.7.4 Menu Structure
The VSODC is equipped with a dual
7-segment LED display and two push buttons (SW2
and TEST). The display and push buttons work
together to allow the technician access to fault recall,
compressor speed locking, and heating mode super
-
heat measurement.
The following process can be used to access any of
these menus:
•
Press the SW2 and TEST buttons for 5-8
sec-
onds.
•
After this time the dual seven segment LEDs will
show the first menu option (FC).
•
To enter a menu, depress the SW2 button.
•
To toggle to the next menu depress the test
button.
•
No action for 5 seconds in the root menu
struc-
ture will return the control to normal operation.
Menu Definition:
FC = Fault Codes – by selecting this menu
the con-
trol will list the stored numerical fault codes in order of
sequence by which they were stored. Depressing the
SW2 button while a fault code is shown will increment
to the next fault. Depressing the TEST button will
force the control back to the main menu.
CS = Compressor Speed – For this selection
menu to
initiate the requested compressor speed, there must
be an active call for compressor operation, the com
-
pressor must be operating, and the selection must be
static for 5 seconds. The Compressor Start and Run,
and Compressor Shut down algorithms will be used
to obtain the requested compressor speed.
•
3 (MAXIMUM Speed)
•
2 (INTERMEDIATE Speed)
•
1 (MINIMUM Speed)
IMPORTANT:
This mode should be
manually exited. If this menu is not exited manually
the VSODC will wait 24 hours before returning to
normal operation. During this time the VSODC will
only request the selected compressor speed.
7.7.5 Replacement of the
VSODC
Each control board in the EcoNet™ Communication
Network needs information specific to the unit the con
-
trol is installed in. This information is called model data
because it is model specific information required for the
communication network to operate properly for the spe
-
cific model installed. The data for a unit contains infor
-
mation that allows the unit to operate correctly. When a
control board requires replacement, it is important that
the replacement board gets the model data from the old
control. The primary way the replacement control gets
this information is by the memory card that should be
installed on the old control. Remove the memory card
from the old control, replace the control, and reinstall
the memory card on the new control. The memory card
from a different unit should never be used.
