Hardware Inputs

UI1: CO2 Sensor

This input is used to connect a space or return CO2 sensor.
The variable CO2Range (NumericConstant2) can be used to configure the range of the CO2 sensor.
The default value is 2000 ppm.
ID
nvoHwInput_1

UI2: UI2

This input is used to connect the Discharge Temperature, Return Temperature, Water Temperature or
Setpoint Offset. It is configurable using UI2Config (EnumConstant2) .
ID
nvoHwInput_2

SI3: SI3

This input is used to connect the Discharge Temperature, Return Temperature, Water Temperature or
Space Temperature. It is configurable using nciMiscConfig.SI3Config (nviFP44) .
ID
nvoHwInput_3

DI4: DI4

This variable is used to connect the window contact. Note that reversing the window contact operation
using DI4Config (EnumConstant3) will not reverse this input. To display the status of the window con-
tact, one should use the variable nvoWindowContact (nvoFP24).
ID
nvoHwInput_4

DI5: DI5

This input is used to connect Auxiliary Contact, Change Over State (heating/cooling) or Condensation
sensor. It is configurable via DI5Config (EnumConstant4).
ID
nvoHwInput_5

DI6: DI6

This input is used to connect Auxiliary Contact, Change Over State (heating/cooling) or Occupation
sensor. It is configurable via DI6Config (EnumConstant5) .
