APPENDIX C — CCN TABLES (cont)
SERVICE CONFIGURATION TABLES
*Not supported.
†0 = No economizer.
**Unit capacity should be entered as nominal size. For DX unit capacity unit
capacity is nominal tonnage. i.e., 92 should be 90 and configure DX cooler
select equal to yes.
NOTES:
1. Table used to disable compressors for maintenance purposes. The
capacity control will consider that these compressors (once set to YES)
are failed manually (no alarm will appear).
2. Enter unit size. This item allows the controls to determine capacity of each
compressor and the total number of fans on each circuit based on a com-
pressor arrangement array (can be viewed in table FACTORY2). It is not
necessary to enter compressor capacity and number of fans on each cir-
cuit. See the 30XA Installation Instructions for more information.
3. Number of fans controlled directly by a variable speed fan actuator using
0 to 10 vdc signal. This will enable the controls to determine the remaining
discrete fan staging outputs from the total fans on each circuit.
4. Used for extra functions with the purpose of energy management such as
occupancy override switch, ice storage, setpoint reset, and demand limit.
5. Compressor capacity will be automatically determined if unit size entered
in FACTORY table matches the values in the unit compressor configura-
tion table.
6. Total number of fans includes fans controlled by a variable speed fan. This
value will be automatically populated if unit size entered in FACTORY
table matches the values in the unit compressor configuration table.
