7. Details of LonWorks Network Variables
[nv1] Unit start/stop command
network input SNVT_switch nviOnOff_00;
network input SNVT_switch nviOnOff_01;
network input SNVT_switch nviOnOff_02;
network input SNVT_switch nviOnOff_03;
These input network variables are used to change the start/stop
status of the indoor unit.
If start/stop is only done from an A/C unit side (as with the remote
controller), then it is not necessary to use these network variables.

0: Stop
1: start
[nv2] Unit start/stop status notification
network output SNVT_switch nvoOnOff_00;
network output SNVT_switch nvoOnOff_01;
network output SNVT_switch nvoOnOff_02;
network output SNVT_switch nvoOnOff_03;
These output network variables are used to provide notification of
the unit's current start/stop status and the thermostat ON/OFF status.
They are also output when the status has been changed from an A/C
unit side (as with the remote controller).
They are output when the LonWorks Interface or the A/C unit
power is reset.
When the indoor units are subject to group control, "thermostat
ON" is output when 1 or more indoor unit is thermostats ON, and
"thermostat OFF" is output when all indoor unit are thermostats
OFF.

state 0: Stop
1: Start
[nv3] Temperature setting command
network input SNVT_temp_p nviSetpoint_00;
network input SNVT_temp_p nviSetpoint_01;
network input SNVT_temp_p nviSetpoint_02;
network input SNVT_temp_p nviSetpoint_03;
These input network variables are used to change the indoor unit
temperature setting.
If the temperature setting is only changed from an A/C unit side (as
with the remote controller), then it is not necessary to use these
network variables.
When a temperature above the upper limit of the temperature which
can be set by the indoor units has been specified, it will be set to the
upper limit; conversely, when a temperature below the lower limit
has been specified, it will be set to the lower limit.

[nv4] Temperature setting status notification
network output SNVT_temp_p nvoSetpoint_01;
network output SNVT_temp_p nvoSetpoint_01;
network output SNVT_temp_p nvoSetpoint_02;
network output SNVT_temp_p nvoSetpoint_03;
These output network variables are output when the temperature
setting status is changed.
They are also output when the status has been changed from an A/C
unit side (with the remote controller).
They are output when the LonWorks Interface or the A/C unit
power is reset.

[nv5] Operating mode setting command
network input SNVT_hvac_mode nviHeatCool_00;
network input SNVT_hvac_mode nviHeatCool_01;
network input SNVT_hvac_mode nviHeatCool_02;
network input SNVT_hvac_mode nviHeatCool_03;
These input network variables are used to change the indoor unit
operating mode.
If the operating mode setting is only changed from an A/C unit
side (as with the remote controller), then it is not necessary to use
these network variables.

* The operating modes that can be set may vary according to the
models of the outdoor and indoor units.
* Settings other than the above are ignored.
[nv6] Operating mode status notification
network output SNVT_hvac_mode nvoHeatCool_00;
network output SNVT_hvac_mode nvoHeatCool_01;
network output SNVT_hvac_mode nvoHeatCool_02;
network output SNVT_hvac_mode nvoHeatCool_03;
These output network variables are output when the operating mode
has been changed.
They are also output when the status has been changed from an A/C
unit side (with the remote controller).
They are output when the LonWorks Interface or the A/C unit
power is reset.
