SAFETY CONSIDERATIONS

Read and follow manufacturer instructions carefully. Follow all
local electrical codes during installation. All wiring must conform
to local and national electrical codes. Improper wiring or installa-
tion may damage Evolution Control System. Recognize safety
information. This is the safety-alert symbol

. When you see this

symbol on the equipment and in the instruction manual, be alert to
the potential for personal injury. Understand the signal words
DANGER, WARNING, and CAUTION. These words are used
with the safety-alert symbol. DANGER identifies the most serious
hazards, which will result in severe personal injury or death.
WARNING signifies a hazard, which could result in personal
injury or death. CAUTION is used to identify unsafe practices,
which would result in minor personal injury or product and
property damage. NOTE is used to highlight suggestions which
will result in enhanced installation, reliability, or operation.

INTRODUCTION

The Network Interface Module (NIM) is used to interface the
following devices to the Evolution ABCD bus so they can be
controlled by the Evolution System. The following devices do not
have communication ability and the NIM is required to control:

•

A Heat Recovery Ventilator / Energy Recovery Ventilator
(HRV/ERV) (when zoning is not applied).

•

A non-communicating single-speed heat pump with a variable-
speed furnace (dual fuel application only).

•

A non-communicating two-speed outdoor unit (R-22 Series-A
unit).

INSTALLATION

I.

CHECK EQUIPMENT AND JOB SITE

INSPECT EQUIPMENT — File claim with shipping company,
prior to installation, if shipment is damaged or incomplete.

II.

COMPONENT LOCATION AND WIRING CONSIDER-

ATIONS

WARNING:

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal
injury or possible equipment damage.
Disconnect power before beginning installation.

NOTE:

All wiring must comply with national, local, and state

codes.

LOCATING NETWORK INTERFACE MODULE (NIM)
— Select a location near the variable-speed furnace or fan coil
where wiring from equipment can come together easily.

NOTE:

Do not mount NIM in outdoor unit. The NIM is

approved for indoor use only and should never be installed with
any of its components exposed to the elements.

The NIM may be installed in any area where temperature remains
between 32° and 158° F, and there is no condensation. Remember
that wiring access is likely the most important consideration.

CAUTION:

ELECTRICAL OPERATION HAZARD

Failure to follow this caution will result in equipment
damage or improper operation.
To prevent possible damage to NIM, do not mount on
plenum, duct work, or flush against furnace.

WIRING CONSIDERATIONS — Ordinary thermostat wire is
ideal when wiring the Evolution System (shielded cable is not
necessary). Use 18 - 22 AWG or larger for typical installations.
Lengths over 100 ft. should use 18 AWG or larger wire. Cut off or
fold back and tape any unneeded conductors. Plan the routing of
wiring early to avoid possible problems later.

NOTE:

ABCD bus wiring only requires a four-wire connection;

however, it is good practice to run thermostat cable having more
than four wires in the event of a damaged or broken wire during
installation.
