of Use Wall Module and Override Priority is given in Table 20:
Optional Digital
Inputs
You can configure digital inputs. The
W7750A can be configured with a

Optional Analog
Inputs
You can configure both resistive and
voltage type analog inputs. The W7750A,
has one resistive analog input that can
be configured. The W7750B, W7750B
Enhanced, and W7750C have two
resistive and two voltage inputs that can
be configured. The W7750C supports the
OutdoorTemp20KNTC sensor type.
Configure one of the following as a
Resistive optional analog point:
• DschgTempPT3000
• OutdoorTempPT3000
• RtnTempPT3000
• DschgTemp20KNTC
• OutdoorTemp20KNTC
• RtnTemp20KNTC
• Unused RAI
Configure one of the following as a
Voltage/current optional analog point:
• Rtn HumidityC7600C
• RtnEnthalpy
• OdHumidityC7600C
• OdEnthalpy
• FilterPress
• SpaceCO2
• MonitorSensor
• Rtn HumidityH7621
• Rtn HumidityC7600B
• OdHumidityH7621
• OdHumidityC7600B
• Unused VAI
The RtnHumidityH7621/31 and
OdHumidityH7621/31 humidity sensors
for voltage inputs are supported by
CVAHUs of model type CVAHU C whose
versions are 2.01.103 and above.
The other humidity sensor models H7620
and H7630 work fine when CVAHU is
configured to use the existing C7600C
humidity sensors.
The DischTemp20KNTC sensor can be
used to report valid temperatures up to
180 °F. This is applicable CVAHU C
models whose versions are 2.01.103 and
above. This is applicable to CVAHU
Model A also whose version is 2.01.13
and above.
