Slow Flash = 1 sec on; 1 sec off.

Fast Flash = 1 msec on; 1 msec off.

A flickering" LED flashes significantly faster than a fast flash.

NOTE − LEDs are energized by 24 vac thermostat inputs.

Startup

Connections between RTU & M2 unit controller

The M2 unit controller connects to the rooftop unit using

SmartWiret connectors. Each connector is keyed" so

that no connector can be installed in the wrong location. Be

sure all connectors are in place and completely inserted

(see figure 1).

Sensor Common Isolation

Thermostat (TSTAT) and humidity (HUM) sensor com-

mons may be isolated if they are powered remotely. Slide

switch to OPEN to isolate (see figure 1).

USB interface usage

The USB port is used for service verification and for down-

loading reports. Onsite data collection requires use of a

USB flash drive. Data written to the drive includes date,

time, serial number, catalog number, basic data, and error

code buffer. Technicians then transfer the data to a PC and

then forward encrypted files to billing personnel for service

history verification.

PC interface

The PC interface is used with unit controller software to

change programming. The M2 interface uses a USB A to B

male cable. You may also continue to use 9 pin/RS485

connection to the phone jack or S−BUS connector as be-

fore. A list of service connection kits is on Page 20.

SmartWire Field Wiring Connections

The SmartWire connectors, P297, P298 and P299, al-

low for easy field wiring connection points.

2−amp fuseThe 24VAC supply outputs, (R), on these

connectors are routed through the fuse, F1. This fuse is a

standard 2−amp, automotive−style blade fuse. This fuse

protects the Prodigy controller from field wiring mis−wires.

TSTAT COMThe switch "TSTAT COM" is located to the

left of P297. This switch is used only in unique situations

where the device supplying the thermostat signals to the

Prodigyt controller has its own power source and does

not share a common reference voltage with the Prodigyt

controller. Otherwise the TSTAT COM switch needs to be

set to the default, closed position, to the right.

HMD COMThe switch "HMD COM" is located to the right

of P299. This switch is used only in unique situations

where the device supplying the dehumidify command sig-

nal to the Prodigyt controller has its own power source

and does not share a common reference voltage with the

Prodigyt controller. Otherwise the HMD COM switch

needs to be set default, closed position, to the left.

User interface menu

The user interface is accessed through the menu naviga-

tion arrows and the select button . The diagram

in figure 2 shows a high level overview of the main menu

options along with the next level list of selections. The low-

er level options are described later in this manual.

Home" location, DISPLAYWhen the unit is powered

on, one of the features in the DISPLAY column will be

shown (the word ’DISPLAY’ is never shown). What is dis-

played in this home" screen, is dependant on the priority

message present at the time, in priority order of top−to−bot-

tom of the left column in figure 2. For example, if an alarm is

present, that will be displayed until it has been silenced or

cleared.

To access the other three columns, first press and then

use to scroll between SERVICE, DATA, AND SET-

TINGS. Next, press to open the SERVICE (or DATA or

SETTINGS) menu. Use

until desired item is dis-

played.

To return to DISPLAY, use

Unit Operation

This section describes the display and control buttons,

how to configure the unit, and how to read stored configu-

ration data, status, and alarms.

The M2 unit controller is an input and output junction

point. If in the thermostat mode, thermostat inputs at

P297 result in an output to unit components (see table 11

on Page 30). If the heartbeat LED is not flashing, see

table 1 (Page 3) for heartbeat operation. If the display

shows an alarm, refer to table 10 (Page 22) for more in-

formation. If the thermostat input indicating lights are not

responding appropriately, check the thermostat or a

DDC control acting as thermostat inputs into P297.

Basic cooling and heating functions may be energized to

test major unit components by using the M2 unit controller

testing function or by using jumper wires on the Field Wir-

ing Termination plug P297.

To access the other three columns, first press and then

use to scroll between SERVICE, DATA, AND SET-

TINGS. Next, press to open the SERVICE (or DATA or

SETTINGS) menu. Use until desired item is dis-

played.

USB Service Verification

When the Lennox USB drive is plugged in during normal

MODE, a message will be displayed to indicate data is be-

ing written to the drive. When finished, the message USB

COMPLETE" will be displayed.

From the USB you may get the last report from the M2 unit

controller and view it using any PC text program.

Multiple units may use the same USB drive. The filename

of the service reports will be based on the unit’s serial num-

ber; for example 5608J5875.txt.

Recommendations

1. Set all BACnet

devices on an MS/TP network to con-

secutive MAC addresses, starting at 1, so that there

are no gaps between MAC address values.

2. Set Max_Master device property on all devices to

match the largest MAC address on the network. Note,

this could be larger than existing network to allow for

adding devices to the network with out the need to ad-

just the Max_Master property in the future.

3. Use ReadPropertyMultiple service instead of Read-

Property service when reading multiple analog inputs

or values.

4. Do not exceed the maximum recommended length

(1200 M / 4000 ft.) for any MS/TP segment.

5. All MS/TP network segment ends should be termi-

nated the same way per manufacturer instructions.

6. To minimize communication compatibility problems,

BACnet gateways or BACnet devices that are NOT

BTL listed should be avoided.

Networking Controllers

A network control panel (NCP) and NCP PC software can

be used to schedule building operation for any M2 on the

same daisy−chained l connection network.

The network thermostat controller (NTC) is an L connec-

tion direct digital controller used on units which are not

equipped with an M2 unit controller. The Building Control-

ler (BC) is used to control building functions such as lights

and signs. Use L connection specific network cable and

daisy chain as shown in figure 5.

Up to 31 controllers can be daisy chained on a single L con-

nection network. Any combination of M2, NTC, and BC

controller can be used.

Economizer (Damper)

General

The economizer, when configured, controls

S damper position, which determines how much outdoor

air is used to meet free cooling or indoor air quality

(IAQ) requirements, and

S the optional power exhaust fans.

On a cooling demand, outdoor air is used for free cooling

instead of first−stage compressor(s) when outdoor air is

suitable (OAS).

Heartbeat LED

Flashing green LED indicates normal operation (See fig-

ure 6).

Outdoor Air Suitable (OAS) LED

A yellow LED which is labeled OAS provides economizer

status. A steady yellow LED indicates that outdoor air is

suitable for free cooling. A flashing yellow OAS light indi-

cates the IAQ sensor requires outdoor air. (A flashing yel-

low LED can also mean that the economizer dampers are

open to bring in fresh air while a compressor is on.) If the

economizer is already operating, a flashing yellow OAS

light indicates the IAQ sensor requires more outdoor air

than is suitable for free cooling.

DIP Switch Settings

The DIP switch setting determines the mode used to en-

able free cooling. The DIP switch also has a mode to set

the damper minimum position and test damper operation.

DIP switch is factory−set when the economizer is factory−

configured.

Free Cooling Discharge Air Setpoint

When outdoor air conditions are suitable and economizer

is set to provide free cooling, dampers will modulate to

achieve a discharge air temperature of 55°F (13°C) de-

fault. This setpoint is adjustable between 45° and 65°F.

The setpoint can also be automatically increased when

outdoor or return air temperatures drop. See Outdoor Air

Reset and Return Air Reset in the Discharge Air Control

section in the advanced setup instructions. These settings

are not accessible through the Prodigy display at this time.

The unit does not have to be operating in discharge air

cooling mode to adjust the setpoint, or to use setpoint re-

set.

During free cooling operation, the damper modulates to its

maximum position where it remains for at least 3 minutes.

If the damper has been continuously in this position for at

least three minutes, then a second stage cooling demand

will be allowed to turn on the first stage of mechanical cool-

ing. While the mechanical cooling is on, the damper is held

to its maximum position, and does not modulate until the

second stage demand is satisfied. On a third stage cooling

demand, the second stage of mechanical cooling will be

turned on.

Outdoor Air Suitability

There are six options available to determine outdoor air

suitability (OAS) for free cooling. See table 8. Economizer

settings are shown for each mode in figure 7.

The appropriate sensors are provided when the economiz-

er is factory−configured. When the economizer is field−con-

figured, the ODE mode requires additional field−provided

sensor(s). See table 8. The TEMP mode uses sensors pro-

vided with all units.

Economizer (Damper) (Continued)

Mode Outdoor air is suitable for free cooling when:

TEMP OFFSET Outdoor air temperature (RT17) is less than return air temperature (RT16) by at least the OFFSET value.

TEMP OAT STPT Outdoor air temperature (RT17) is less than the OAT STPT value.

Remote

Either of the TEMP modes can be used when a network OAS signal is provided by an energy management or building

control system, via BACnet, LonTalk, or L Connection. The network can command OAS, NOT OAS, or AUTO. AUTO

returns to local control of OAS, which is the selected TEMP mode..

ENTH (differential) Outdoor air enthalpy* (A7) is less than return air enthalpy (A62). Enthalpy setpoint potentiometer is set to DIFF

ENTH (setpoint) Outdoor air enthalpy (A7) is less than enthalpy setpoint potentiometer position A, B, C, or D.

GLOBAL

Global input is energized by (P297−9). This setting is also used for outdoor air damper applications. Global input also

brings on the blower. (This mode is NOT used when OAS signal is provided via network connection. GLO is only used

when a 24VAC signal is used to energize the P297−9 GLO input.)

Enthalpy includes effects of both temperature and humidity.
