nciSetPnts standby_cool SNVT_temp_p
50 to 95°F (10 to 35°C)
77°F (25°C) This is the configured setpoint which applies to the standby cooling
mode. Where the ZEB for standby is used, it is derived from the
difference between standby_cool and standby_heat.
nciSetPnts unoccupied_cool SNVT_temp_p
50 to 95°F (10 to 35°C)
82.4°F (28°C) This is the configured setpoint which applies to the unoccupied cooling
mode.
nciSetPnts occupied_heat SNVT_temp_p
50 to 95°F (10 to 35°C)
69.8°F (21°C) This is the default setpoint for the occupied heating setpoint which is
used in case there is no locally wired setpoint knob or nviSetpoint has
not been bound. Where the ZEB for occupied is used, it is derived from
the difference between occupied_cool and occupied_heat.
nciSetPnts standby_heat SNVT_temp_p
50 to 95°F (10 to 35°C)
66.2°F (19°C) This is the configured setpoint which applies to the standby heating
mode. Where the ZEB for standby is used, it is derived from the
difference between standby_cool and standby_heat.
nciSetPnts unoccupied_heat SNVT_temp_p
50 to 95°F (10 to 35°C)
60.8°F (16°C) This is the configured setpoint which applies to the unoccupied heating
mode.
nciWallMod ui_bypass_time UWORD
0 to 1080 minutes
180 min This configuration variable specifies the time the controller remains in
OCCUPIED mode before reverting to the original occupancy mode
after pressing the override button at the wall module or initiating
BYPASS via the network. When the bypass mode has been activated,
the bypass timer is set to ui_bypass_time. When the timer expires,
nvoFcuStatus.occ_status.hw_override reverts from OC_BYPASS to
OC_NUL to quit the bypass override function.
nciWallMod si_low_setpt SNVT_temp_p
-9 to 9 DDF (-5 to 5 K) for
relative
53.6 to 86°F (12 to 30°C) for
absolute
-9 DDF (-5 K)
(53.6°F (12°C) for
absolute setpoint)
This configuration variable specifies the low limit for the setpoint knob.
It can be relative or absolute depending upon the configuration in
nciWallMod.set_pnt_knob.
nciWallMod si_high_setpt SNVT_temp_p
-9 to 9 DDF (-5 to 5 K) for
relative
53.6 to 86°F (12 to 30°C) for
absolute
9 DDF (5 K)
(86°F (30°C) for
absolute setpoint)
This configuration variable specifies the high limit for the setpoint knob.
It can be relative or absolute depending upon the configuration in
nciWallMod.set_pnt_knob.
nciWallMod si_space_temp_zero_
cal
SNVT_temp_p
--9 to 9 DDF (-5 to 5 K)
0 DDF (0 K) The space temperature sensor is corrected by adding this calibration
setting (an offset value) to the sensed value.
