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 Infinity 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 Infinity System consists of intelligent communicating com-

ponents (User Interface, variable speed furnace or fan coil, AC or

HP), which continually communicate with each other via a

four-wire connection called the ABCD bus. Conventional 24-volt

signals on dedicated wires are not needed. Commands, operating

conditions, and other data are passed continually between the

components over the ABCD bus. The result is a new level of

comfort, versatility, and simplicity.

An Infinity System consists of a Infinity Control™ (thermostat

plus much more) and an Infinity furnace or fan coil. All Infinity

furnaces or fan coils are variable-speed and multi stage for

maximum flexibility, efficiency, and comfort. They support con-

trolled ventilation, humidification, dehumidification, and air qual-

ity control. Either an Infinity dual capacity (communicating), or a

standard 24 vac controlled outdoor unit may be used.

When using conventional outdoor units, the Infinity furnace or fan

coil provides the 24 volt signals needed to control them. Also, the

Infinity Network Interface Module (NIM) allows connection of a

conventional HRV or ERV without the need for a separate wall

control.

All system components are controlled through the wall mounted

Infinity Control™, which replaces the conventional thermostat and

provides the homeowner with a single wall control for all the

features of the system.
