CAUTION
Electrostatic discharge can affect electronic components.
Take precautions during unit installation and service to protect the unit’s electronic controls. Precautions will help to avoid control exposure to electrostatic discharge by
putting the unit, the control and the technician at the same electrostatic potential. Neutralize electrostatic charge by touching hand and all tools on an unpainted unit surface
before performing any service procedure.

IMPORTANT
Improper installation, adjustment, alteration, service or maintenance can cause personal injury, loss of life, or damage to property.
Installation and service must be performed by a licensed professional installer (or equivalent) or a service agency.

IMPORTANT
When adding this module to an existing M2 Unit Controller, the M2 firmware must be v7.07 or higher.

To configure the LonTalk Network

Go to RTU MENU > NETWORK INTEGRATION > NETWORK SETUP WIZARD = LONTALK

Operation and Functional Description

LONWORKS NETWORK CONNECTION
The LonTalk module has an FTT-10A Free Topology Transceiver for network communication. The FTT-10A transceiver network supports free topology wiring and will accommodate bus, star, loop, or any combination of these topologies. The module can be located at any point along the network wiring. This capability simplifies system installation and makes it easier to add nodes when required.

LONWORKS NETWORK CABLE
The LonWorks TP/FT-10 network requires Echelon qualified twisted-pair communication cables such as Belden 8471 or NEMA Level 4 cables. Other Echelon approved equivalent cables may also be used depending on the application. The Belden 8471 or NEMA Level 4 cables are rated for plenum use.

The network cable should be routed using best practices to avoid induced noise. Do not route alongside power lines, or in proximity to high voltage or high-frequency devices, such as ignition controls and variable frequency drives. The average temperature of the wire must not exceed 131°F (55°C).

NETWORK LIMITS (FREE TOPOLOGY)
The LonWorks TP/FT-10 free topology network is limited to a maximum of 64 nodes per segment. The maximum total bus length and the maximum node-to-node length is1640

ft. (500 m) for Belden 8471 or NEMA Level 4. Maximum lengths are less for other smaller wire size cables.
Only one termination circuit module is required at any location along with the network. Refer to Echelon LonWorks FTT- Transceiver User’s Guide for additional details.

FREE TOPOLOGY NETWORKS
Free topology segments require a termination circuit for proper performance. Only one termination circuit module is required at any location along with the network.

NETWORKS LIMITS (DOUBLY–TERMINATED TOPOLOGY)
The LonWorks TP/FT-10 Doubly-Terminated topology network is limited to a maximum of 64 nodes per segment. The maximum total bus length is 5000 feet (1524 meters) for Belden 8471 or NEMA Level 4. Maximum bus lengths are less for other smaller wire-size cables. The maximum stub length is 9.8 ft. (3 m). In many cases, this bus network is connected in a daisy chain manner where the bus is wired directly to each node, so the stub length is zero.

Two field-provided termination circuit modules are required for each segment. One must be located at each end of the network.

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. The unused termination module wire must be covered with a wire nut to prevent potential grounding problems.

NETWORK INTEGRATION
A network configuration tool such as LonMaker® is required 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 Interface 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 function block.

ZONE OR ROOM SENSOR CONTROL
In order to use room temperature setpoints, the Prodigy unit controller must be configured for Zone Temperature control mode. This may be done through the Prodigy display.

PRODIGY – M2 ZONE SENSOR CONTROL CONFIGURATION
PROCEDURE
In order to use nviSpacelAQ, nviSpaceRH, or NVI SpaceTemp, the Prodigy M2 unit controller must be configured.

Go to the M2 Unit Controller user interface.
Use the select button to enter the menu, and use the up/ down buttons to scroll through the options.
Go to SETTINGS > 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.

PRODIGY – M3 ROOM SENSOR CONTROL CONFIGURATION
Procedure

In order to use nviSpacelAQ, nviSpaceRH or nviSpaceTemp, the Prodigy M3 unit controller must be configured.

Go to the M3 Unit Controller user interface.

Go to SETTINGS > GENERAL > CONFIGURATION ID 1 and verify or change position 5 is set to
Go to: SETUP > NETWORK INTEGRATION and set to TALK.
Set CONTROL MODE to either MONITOR ONLY or ROOM SENSOR. If ROOM SENSOR is selected, then enabled the applicable sensors (CO2, RH or TEMP).

CORE UNIT CONTROLLER (M4) ROOM SENSOR CONTROL
CONFIGURATION PROCEDURE

In order to use nviSpacelAQ, nviSpaceRH or nvi SpaceTemp, the CORE unit controller must be configured.

Go to the LENNOX® CORE SERVICE APR

Go to RTU MENU > INSTALL > CONFIGURATION ID 1 and verify or change position 5 is set to L.
Go to SETUP > NETWORK INTEGRATION and set to
Set CONTROL MODE to either MONITOR ONLY or ROOM SENSOR. If ROOM SENSOR is selected, then enabled the applicable sensors (CO2, RH or TEMP).

DATA UPDATE RATE

If nviSpaceTemp, nviOutdoorTemp, nviSpaceRH, or nviSpacelAQ are used, the data needs to be updated within five minutes to be valid.

LANDMARK FUNCTION PROFILES
The Prodigy LonTalk module contains two LonWark functional 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.

NVI DUPLICATION
nviOccSchedulel, (in sccRooftop), and nviOccSchedjle, (in dischargeAirCont), are duplicate network variable inputs 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.

LonTalk Occupancy Signals and Blower Operation

This section describes how LonTalk occupancy signals are combined to produce effective occupancy along with the applicable unit controller parameter setting.

PRODIGY M2 UNIT CONTROLLER BLOWER OPERATION WITH EFFECTIVE OCCUPANCY

This section describes how LonTalk occupancy signals are combined to produce effective occupancy.

The blower runs to service heat and cool demands, regardless of the space occupancy. But when there is no heating or cooling demand there are options for how the blower should operate in conjunction with occupancy signals to keep the space ventilated, or the air stirred.

In SETTINGS > CONTROL menus the option for BLOWER ON OCP is selected as CYCLES or ALWAYS ON. These correspond to ECTO 6.17 settings of 0 or 1, respectively. These settings govern whether the blower runs continuously when the space is considered occupied (=1), or cycles on/ off with the heating and cooling demand (=0). ECTO 6.17 only applies to the room sensor control modes, and not to the local or network thermostat modes. In those modes, the blower is controlled by the G thermostat or DDC signal.

To comply with the California Energy Commission Title 24 standard there are two additional blower/occupancy settings that are set directly by changing ECTO 6.17 from the SETTINGS > CONTROL > ECTO menu. These two additional options are available when using LonTalk and supply a room occupancy signal (in addition to the scheduled occupancy).

There are two new CEC Title 24 settings for ECTO 6.17. Those two options are 2 and 3 and a description of both are provided in table 8.

Table 8. ECTO 6.17 Description

ECTO 6.17	Occupancy Blower Duty Description
0	Blower cycles on/off with demand. (Legacy usage.)
1	The blower runs when either the occupancy sensor or schedule or both, indicates occupied. (Legacy usage.)
2	The blower runs when both the occupancy sensor and schedule indicate occupied.
3	The same as option 2, but the blower runs for 30 minutes and is off for 90 minutes when the schedule is occupied but the occupancy sensor is not occupied.

Table 9. Blower Operation Description

PRODIGY M3 UNIT CONTROLLER BLOWER OPERATION WITH EFFECTIVE OCCUPANCY

This section describes how LonTalk occupancy signals are combined to produce effective occupancy.

The blower runs to service heat and cool demands, regardless of the space occupancy. However when there is no heating or cooling demand there are options for how the blower should operate in conjunction with occupancy signals to keep the space ventilated, or the air stirred.

California Energy Commission Title 24:
a. The legacy option settings for OCC Blower Mode are AUTO CYCLES or ON-CONTINUOUS 1. These settings govern whether the blower runs continuously when the space is considered occupied or cycles on/off with the heating and cooling demand.
b. To comply with the California Energy Commission Title 24 standard there are two additional values for OCC Blower Mode which are ON-CONTINUOUS 2 and ON-CONTINUOUS 3. See table 13 for their descriptions.
c. These two new options are available when using LonTalk that supplies a room occupancy signal (in addition to the scheduled occupancy).

Enabling Network Type To enable the network module, go to SETUP > INSTALL and run the setup wizard. When Configuration ID 1 appears on the screen, configure position 5 to L = LonTalk.

Menu Setup Procedure Method for OCC Blower Mode These blower control options are handled by the OCC Blower Mode. These setting can be changed using the following menu path:

Go to SETUP > NETWORK INTEGRATION > NETWORK = LONTALK > (additional prompts concerning network configuration and sensor types will be asked) CONTROL MODE = ROOM SENSOR > ROOM SENSOR OCC BLOWER MODE =.
