Network Variables Input
nviSpaceTemp
This variable is used to receive the Space Temperature from an external node on the network.
This variable has priority over the local space temperature inputs. If this variable is received, the con-
troller will use this value to control and will output the value in nvoSpaceTemp.
The only variable that can override nviSpaceTemp is nviSpaceTempAvg. For more details, refer to
nviSpaceTempAvg(nviFP15).

nviSetpoint (nviFP01)
This input network variable is used to allow the temperature setpoints for the occupied and standby
modes to be changed via the network.
If a valid value is not present, either a locally wired setpoint knob or the appropriate setpoint as config-
ured in nciSetpoints will be used.
Note: The unoccupied setpoints are not changed.
The effective heat/cool setpoints for the occupied and standby modes are derived from nciSetpoints
plus the absolute setpoint offset, calculated as the difference between nviSetpoint and the mean of the
occupied_heat and occupied_cool setpoints defined in nciSetpoints:
£
abs_setpoint_offset = nviSetpoint - (occupie occupied_heat)/2
£
effective_occupied_cool = occupie abs_setpoint_offset
£
effective_occupied_heat = occupie abs_setpoint_offset
£
effective_standby_cool = standb abs_setpoint_offset
£
effective_standby_heat = standb abs_setpoint_offset
If nviSetpoint and nviSetptOffset are used together, the result on the effective setpoints is cumulative.

nviSpOffset (nviFP02)
This input network variable is used to shift the effective occupied and standby temperature setpoints
by adding nviSetptOffset to the current setpoints.
It is typically bound to a supervisory node or to an external wall module having a relative setpoint
knob.
All occupied and standby setpoints will be shifted upward (+) or downward (-) by the value of nviSpOff-
set.
Note: The unoccupied setpoints are not changed.
If nviSetpoint and nviSetptOffset are used together, the result on the effective setpoints is cumulative.
