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:

• User Interface — Each installation has only 1 User Interface. This is the command center for the entire system, and it will typically be located in Zone 1 to sense and control the temperature in this zone. If desired, a Remote Sensor may be used to sense the Zone 1 temperature. This can give the installer some flexibility in locating the User Interface to another area. • Remote Sensor — This is a temperature sensor only, having no additional user inputs.

Step 4—Install Zone Dampers 1. Open doors or remove cover to access mounting holes (remove the 2 Zone system cover from the left side first). Proper selection and sizing of dampers is very important for proper system operation. Be sure to consult the Zoning Design Manual for assistance in making these selections. Selection and sizing information is not provided in this installation instruction. 2. Mount back plate to wall using screws and wall anchors provided. 3. Level back plate and tighten screws.

3. Properly seal joint using duct tape, mastic, or other approved method. Do not allow mastic to come in contact with actuator. 4. Insulate damper using 1-1/2 in. to 2-in. insulation. (Check your local codes.) S-LOCK NOTE: All zone dampers and duct work must be properly supported according to local codes or SMACNA standards. RECTANGULAR METAL DUCT WORK 1.

For heat pumps with electric aux heat and outdoor temperatures below 12 degrees F., any heat call is accompanied by a W1 signal, bringing on the first stage of aux heat to again increase leaving air temperature. Factory default is OF (off). on, it will remain on until the demand is satisfied. The following cycle will start with the heat pump.

shut down the equipment when the LAT temperature reaches its limit. If the equipment is shut down by a LAT or HPT limit trip, the small ’equipment on’ triangle on the display will be flashing to indicate this condition. Continuous fan is energized during a LAT/HPT Limit Trip. This is true for both heating and cooling. As with earlier Comfort Zone systems, temperature set here was temperature where actions were started. Shutdown temperature was 20°F higher than selected temperature.

Step 3—Quick Check of Equipment Operation Comfort Zone II -B provides superior convenience and features. When installing a 24-vac humidifier, connect it directly to the HUM terminal on the Equipment Controller and C terminal of indoor equipment. Either this or the next step (Step 4) may be used for initial startup. This check runs equipment for only 2 minutes on each stage and is adequate to see that each stage comes on properly. For temperature rise, charge levels, etc.

applications, this is an improvement over using an external humidistat, which only supplies humidity when auxiliary heat is on. compressor operate at high speed only for any cooling demand. High speed provides better water removal than low speed when a 2-speed compressor is used with PSC blower. 2. Fan Humidify Mode—This configuration allows a humidity demand to turn on the fan and the humidifier together, even if there is no heat demand.
PAGE 15
With any dehumidify selection, if the system has 2-speed compressor (DIP switch 2 is ON) and does not have a variable speed blower (configuration option 5 is set to OFF), all cooling will be done at high speed while a dehumidify demand exists. This is because the combination of a 2-speed compressor without a variable speed blower generally has poor humidity removal on low speed.

removed to enable the DEHUM input. See Table 6 and Fig. 31 through 34. When a dehumidify demand exists, the furnace control reduces the blower airflow by 21%. These indicate when cooling or heating equipment is actually operating. When arrows flash, equipment is waiting to come on but is being held off by compressor timeguard, cycle timer, or because LAT or HPT has exceeded its limits and temporarily turned equipment off.

SMART SENSOR OPERATION NOTE: Refer to Smart Sensor Installation and Start-Up Instructions for proper installation and set-up procedure. The Smart Sensor can control the setting of zone temperature, OUT, HOLD, or OFF. It can also display outdoor temperature and indoor humidity. Hold Out Set Temp Fig. 13—Comfort Zone II — Smart Sensor A97186 → CHANGING SET POINT 1. The current temperature in that zone will be displayed in the LCD. 2. Press UP or DOWN button once to display set point for that zone.

The OUT function is also a programmable option. You can program the OUT function in the program schedules. If a zone is set to OFF, the OUT button will have no effect. OFF must be cancelled before OUT can become active. At the Smart Sensor(s): Same as the above; pressing OUT button will program the zone as being unoccupied. Pressing OUT button again changes the zone to occupied. When a zone is set to OUT, the desired temperature will be displayed as "--" when UP and DOWN buttons are pushed.
