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:
