Manual Identification
Neuron ID of a device can also be entered manually through a commissioning or service tool. Neuron ID should
be located on the Echelon chip of the device being commissioned.
Figure 8 shows an example of a Manual Neuron ID request made through a commissioning tool.

Tips And Things You Need To Know
In order to operate nviAuxOut (auxiliary output) from the network, Aux contact configuration (Auxcont
nciGenOpt) needs to be set as “Network Controlled”;
If the heartbeat is lost, the module will release the network sensor value for the Room Temperature
(nviSpaceTemp) and the Outdoor Temperature (nviOutdoorTemp);
The SeqOpera value (Sequence of Operation) depends on the nviHeatCool value and nviAuxHeatEnable
value. See note 1 on page 15 for all the details;
Troubleshooting Section
Error / Trouble
Condition Possible Cause Solution
The LON network has too many
devices. Do not exceed the maximum number of
devices and maximum length allowed
