SAFETY CONSIDERATIONS

Improper installation, adjustment, alteration, service, maintenance,

or use can cause fire, electrical shock, or other conditions which

may cause personal injury or property damage. Consult a qualified

installer, service agency or your distributor or branch for informa-

tion or assistance. The qualified installer or agency must use

factory-authorized kits or accessories when modifying this prod-

uct. Refer to the individual instructions packaged with the kits or

accessories when installing.

Follow all safety codes and wear safety glasses. Have fire

extinguisher available. Read these instructions thoroughly and

follow all warnings or cautions attached to the unit. Consult local

and state building codes and Sheet Metal and Air Conditioning

National Association (SMACNA) for special installation require-

ments.

Recognize safety information. This is the safety-alert symbol

When you see this symbol on the unit or in instructions and

manuals, be alert to the potential for personal injury.

Understand the signal words DANGER, WARNING, and CAU-

TION. These words are used with the safety-alert symbol. DAN-

GER identifies the most serious hazards which will result in severe

personal injury or death. WARNING signifies hazards 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.

INSTALLATION CONSIDERATIONS

Before the actual installation of a zoning system can begin,

decisions need to be made to determine the number and location of

zones and sensors. This affects duct and damper selections. For

assistance with these decisions, consult the Zoning Design Guide

available from your distributor or branch.

This instruction covers the physical installation and start up of the

Comfort Zone II -B system. Use this instruction to guide the actual

installation process after all the air side decisions have been made.

1. Install User Interface and Remote Sensors in non-condensing

areas with ambients between 32°F and 120°F. Install Dampers

and Equipment Controller in non-condensing areas with

ambients between 32°F and 158°F.

2. A TXV is required on the indoor coil when used with all

residential split system equipment.

3. Use separate isolated transformer to supply power to Comfort

Zone II -B System (40 va minimum, class 2, field supplied).

4. Proper equipment and duct sizing are important in a zoned

system. Be sure to refer to the Zoning Design Guide for

assistance in making these selections.

TXV on indoor coil is required with all residential split

system equipment.

INTRODUCTION

The Comfort Zone II -B System allows air conditioning and

heating equipment to control temperatures and humidity in up to 8

distinct spaces or Zones within a building. Each zone has inde-

pendent temperature settings.

The comfort temperature settings can change automatically

through the use of schedules. This allows Comfort Zone II -B to

change temperature settings in zones to reflect occupancy or usage.

For example, you can condition the bedrooms in a home from 5:00

PM through 7:00 AM or the kitchen from 3:00 PM through 6:00

PM. The Comfort Zone II -B System uses motorized air volume

control dampers (also called zone dampers) to regulate flow of

conditioned air into zones. In this manner Comfort Zone II -B can

selectively heat or cool certain portions of a building depending

upon space temperature requirements.

Each zone requires a motorized zone damper to control the air

supplied to it and a zone sensor to sense zone temperature. There

are 4 types of zone sensors available and they may be used in

combination:
