Network Bus Termination
To install the network bus terminal module 37X75, connect
the brown and yellow wires to the network bus that requires
single termination and connect the brown and orange wire
to the network bus that requires double termination. See
figure 7. The unused termination module wire must be cov
ered with a wire nut to prevent potential grounding prob
lems.
Network Integration
A network configuration tool such as LonMaker
®
is re
quired to commission the LonWorks network. Press the
service button on the LonTalk module to generate a service
message that contains the Neuron ID.
Other commissioning methods may be used. The Neuron
address is located on the LonTalk module. An external In
terface File (XIF) is available for configuration prior to
installation.
Prodigy
®
Reset
The Prodigy unit controller may be reset using nviRequest
with enumeration RQ_RESET sent to NodeObject func
tion block.

Setup
In order to use zone temperature setpoints, the Prodigy
unit controller must be configured for Zone Temperature
control mode. This may be done through the Prodigy dis
play. Use the select button to enter the menu, and the
up/down buttons to scroll through the options. Go to SET
TINGS > CONTROL > LONTALK > CONTROL MODE
and select ZONE for the Zone Temperature control mode.
This is the same as setting the Prodigy ECTO (Electronic
Config To Order) parameter 6.01 to a value of 1.
In order to use nviSpaceIAQ, nviSpaceRH or nviSpace
Temp, the Prodigy unit controller must be configured. Go to
SETTINGS > CONTROL > LONTALK and step through
until NETWORK SENSORS and select YES for the ap
propriate sensor (CO2, RH or TEMP). This is the same as
setting the Prodigy ECTO 5.27.
Data Update Rate
If nviSpaceTemp, nviOutdoorTemp, nviSpaceRH or nvi
SpaceIAQ are used, the data needs to be updated within 5
minutes to be valid.
LonMark Function Profiles
The Prodigy LonTalk module contains two LonMark func
tional profile function blocks, Space Comfort Controller-
Rooftop and Discharge Air Controller. It also contains a
Lennox specified functional block, a virtual function block
containing the network configuration variables and a node
object. See figure 4.
NVI Duplications
nviOccSchedule1, (in sccRooftop), and nviOccSchedule,
(in dischargeAirCont), are duplicate network variable in
puts and only one should be used.
Also, nviFanSpeedCmd and nviSupFanCap have the
same functionality and only one should be used.
Both nviSetpoint and nviHCSetpoints change the effective
temperature setpoints and only one of them should be
used.
