EXCEL 10 W7750A,B,C CONSTANT VOLUME AHU CONTROLLER
74-2958—170
nciIoSelect FiftySixtyHz SIXTYFIFTY 01 SIXTY P X FiftySixtyHz specifies the frequency of the main power input for the
controller. Correctly selecting the FiftySixtyHz decreases the noise picked
up by analog switch wiring from the power mains. When FiftySixtyHz is 0
(SIXTY is the default), the mains frequency is sixty Hz and when
FiftySixtyHz is 1 (FIFTY), the mains frequency is fifty Hz.
nciIoSelect SpaceSensorType T7770 0 T7770 X SpaceSensorType specifies the type of space temperature sensor
connected to the node. When SpaceSensorType is 0, a T7770 sensor is
connected to the sensor terminals. No other options are currently valid.
RmtStptPot nvoIO siSetPointTempS7 Degrees F

Degrees C
(-23 to 29)
SI_INVALID M,
S
X X X SetPointTemp is the wall module setpoint temperature. When
nciConfig.SetPointTemp is ABSOLUTE_COOL or ABSOLUTE_MIDDLE,
the reported value is the absolute setpoint temperature. When
Config.SetPntKnob is OFFSET, the reported value is the offset (from the
current active TempSetPts) temperature. If the input is not configured or
has failed, the value is SI_INVALID.
RmTempSensr nvoIO siSpaceTempS7 Degrees F
40 to 100
Degrees C
(4 to 38)
SI_INVALID M,
S
SpaceTemp is the measured space temperature. If the sensor is not
configured or has failed, the value is SI_INVALID.NOTE: The reported
temperatures includes the offset correction provided by
Config.ResistiveOffsetCal.
DaTempSensr nvoIO siDischargeTempS7 Degrees F Degrees C
30 to 122 (-1 to 50)
SI_INVALID DischargeTemp is the measured discharge air temperature. If the sensor is
not configured or has failed, the value is SI_INVALID. Refer to the note on
SpaceTemp.
RaTempSensr nvoIO siReturnTempS7 Degrees F Degrees C
30 to 122 (-1 to 50)
SI_INVALID ReturnTemp is the measured return air temperature. If the sensor is not
configured or has failed, the value is SI_INVALID. Refer to the note on
SpaceTemp.
RaHumSensr nvoIO ReturnHumidity Percentage
10 to 90
SI_INVALID ReturnHumidity is the measured return air humidity. If the sensor is not
configured or has failed, the value is UB_INVALID.NOTE: The reported
temperatures includes the offset correction provided by
Config.VoltageOffsetCal.
RaEnthSensr nvoIO siReturnEnthalpyS7 mA
4 to 20
SI_INVALID ReturnEnthalpy is the measured return air enthalpy. If the sensor is not
configured or has failed, the value is SI_INVALID. Since the C7400 reports
comfort due to enthalpy (btu/lb) in milliamps, enthalpy is also reported in
milliamps. Refer to the NOTE on ReturnHumidity.
OaTempSensr nvoIO siOutdoorTempS7 Degrees F Degrees C
-40 to 122 (-40 to 50)
SI_INVALID M,
S
OutdoorTemp is the measured outdoor air temperature. If the sensor is not
configured or has failed, the value is SI_INVALID. Refer to the NOTE on
ReturnHumidity.
OaHumSensr nvoIO OutdoorHumidity Percentage
10 to 90
SI_INVALID M,
S
OutdoorHumidity is the measured outdoor air humidity. If the sensor is not
configured or has failed, the value is UB_INVALID. Refer to the NOTE on
ReturnHumidity.
OaEnthSensr nvoIO siOutdoorEnthalpyS7 mA
4 to 20
SI_INVALID M,
S
OutdoorEnthalpy is the measured outdoor air enthalpy. If the sensor is not
configured or has failed, the value is SI_INVALID. Since the C7400 reports
comfort due to enthalpy (btu/lb) in milliamps, enthalpy is also reported in
milliamps. Refer to the NOTE on ReturnHumidity.
FltrPressSensr nvoIO siFilterPressureS10 inw (kPa)
0 to 5 (0 to 1.25)
SI_INVALID FilterPressure is the measured differential pressure across the return air
filter. If the sensor is not configured or has failed, the value is the
SI_INVALID. Refer to the NOTE on ReturnHumidity.
