Net Data Type
SNVT The effective loading on the controller. A positive value indicates a cooling load and
lev_percent a negative value will indicate that there is a heating load.
The Terminal Load calculation is controlled by nciCZS.type
Conventional calculation uses the PID output of heating and cooling controls. When
the controller is switched to the heating mode, the Terminal load
-160% ≤ range
CZS calculation uses the Proportional output of heating and cooling controls. When
the controller is switched to the heating mode, the Terminal Load continues to report
both heating and cooling demand. The terminal load absolute value is truncated at
100%
≤
-100% range

SNVT VAV Controller status.
hvac_status Use the application UnitStatus to add this NV to your Lon controller. Refer to the
Appendix for details.
0 – Auto heating and cooling
1 – Heat
2 – Morning warm-up
3 – Cooling
4 – night purge
5- Pre Cool
6 – heating and cooling off
Reports the current percentage of ReHeat stages or modulating ReHeat turned on.
When ReHeat is not configured, UnitHeat is set to Invalid.
0 - 100%
Reports the current percentage of peripheral Heat demand. When peripheral Heat
is not configured this value is set to Invalid.
0 – 100%
Reports the current percentage of cooling air delivered to the zone.
0 – 100%
Set to invald
