AV: 8: Cooling Stage 2 Offset. This is the offset value from AV:6, which will activate the second
stage cooling. If the Intake Air Temperature rises above AV:6 + AV:8, 2
nd
stage cooling will
enable.
Properties
- Editable, precision to the tenth of a degree
- BACnet Reference: cl_s2_ofst
- Modbus Register: 40009
- N2 Register: 5
- Lonworks ID: nviCoolTwoOfst
- Units of degrees Fahrenheit (can be changed in software)
- Range: 1.0 to 30.0
AV: 9: Effective Discharge Air Temperature. This is the effective discharge air temperature, as
read from the unit’s internal discharge air sensor.
Properties
- Fixed readout. Non-editable
- BACnet Reference: edat
- Modbus Register: 40015
- N2 Register: 8
- Lonworks ID: nvoEffDisAirTemp
- Units of degrees Fahrenheit (can be changed in software)
- Range: -25.0 to 225.0
- Type II 10K Thermistor
AV: 10: Cooling Stage 1 Off Delay. This is the time, in minutes, of which the stage 1 cooling
must remain on after stage 2 cooling has been disabled. This prevents cycling between stage 1
and stage 2 cooling.
Properties
- Editable using integer values only
- BACnet Reference: s1_cl_dly
- Modbus Register: 40007
- N2 Register: 4
- Lonworks ID: nviCoolOneOffDly
- Units of minutes
- Range: 1 to 30
- Default: 5
AV: 11: Cooling Stage 2 On Delay. This is the time, in minutes, of which the stage 1 cooling must
be on before stage 2 cooling is allowable. This prevents abrupt cooling demand if the network
were to have a large fluctuation of intake air temperature values.
Properties
- Editable using integer values only
- BACnet Reference: s2_cl_dly
- Modbus Register: 400011
- N2 Register: 6
- Lonworks ID: nviCoolTwoOnDly
- Units of minutes
- Range: 1 to 30
- Default: 5
