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 “NetworkControlled”;
If the heartbeat is lost, the module will release the network sensor value for the Room Temperature
(nviSpaceTemp) and the Outdoor Temperature (nviOutdoorTemp);
The heartbeat parameter of a Tridium front-end should be set at the slowest configuration possible so
that nviTimeStamp updates correctly;
With any LNS Tools, nviTimeStamp should be set to refresh everyday or on power-up;
For nciMultOpt, Viconics strongly recommend to use either one of the following format file:
• UNVT_rt_opts#US or UNVT_rt_opts#SI for Roof Top models
• UNVT_hp_opts#US or UNVT_hp_opts#SI for Heat Pump models
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
by the EIA-485 specifications.
Too many devices were installed
without any repeaters. Repeaters need to be installed as
specified in this document.
The LON cable runs are broken Locate the break and correct wiring
Thermostat does not
come online
The thermostat does not have power Apply power to the thermostat
