Comments
nciDeviceName ASCII Blanks DeviceName is an 18 character field used to identify the node uniquely as
one object at the site or project. The contents of the DeviceName is
maintained by a management node. If DeviceName is all ASCII blanks, it is
considered unconfigured.
nciApplVer application_type 0 to 255 0 ApplicationType identifies the current application number of the Excel 10.
nciApplVer version_no 0 to 255 0 VersionNumber identifies the version number of the Excel 10 application.
nciApplVer time Seconds 0 The time stamp of the last change to the Excel 10 application
configuration. Time meets the ANSI C time stamp requirement specifying
the number of seconds elapsed since midnight (0:00:00), January 1, 1970.
It is represented in the Intel Format.
FanMode nciConfig FanMode AUTO_FAN

AUTO_FAN P X X FanMode specifies the operation of the fan. If the FanMode is 0
(AUTO_FAN), then the fan cycles on and off with demand for cooling and
may cycle with heating if FanOnHeat is TRUE. If the FanMode is 1
(CONTINUOUS_FAN), then the fan runs continuously when the effective
occupancy is OC_OCCUPIED or OC_BYPASS. The fan cycles on and off
with demand for cooling and may cycle with heating if FanOnHeat is TRUE
during the OC_UNOCCUPIED or OC_STANDBY modes.

P X X SmokeControl specifies the operation of the economizer damper and the
fan when the mode is SMOKE_EMERGENCY.
HeatCycHr nciConfig ubHeatCph 2 to 12 6 P X X HeatCph specifies the mid-load number of on/off cycles per hour when the
mode is HEAT. In addition the cycle rate specifies the minimum on and off
time. Refer to Table 17 Interstage Minimum Times of the System
Engineering Guide for the actual values.
CoolCycHr nciConfig ubCoolCph 2 to 12 3 P X X CoolCph specifies the mid-load number of on/off cycles per hour when the
mode is COOL. In addition the cycle rate specifies the minimum on and off
time. Refer to Table 17 Interstage Minimum Times of the System
Engineering Guide for the actual values.
FanRunOnCool nciConfig ubFanRunonCoolS0 Seconds
0 to 120
0 P X X FanRunonCool specifies how long the fan runs after all the cooling stages
have turned off. The fan is turned off FanRunonCool seconds after all the
cooling demand has turned off.
FanRunOnHeat nciConfig ubFanRunonHeatS0 Seconds
0 to 120
0 P X X FanRunonHeat specifies how long the fan runs after all the heating stages
have turned off. The fan is turned off FanRunonHeat seconds after all the
heating demand has turned off.
