Specifications subject to change.

The Zoneline 4100 and 6100 Series have incorporated changes suggested by customers, along with enhancements by GE’s Technology Team and changes necessary to meet new UL and NEC requirements.

“L” shaped condenser coil.

Cross-flow blower across the product line for quieter operation.

The “Partial Open Vent Air” feature was a specific request by a customer.

“Heat Sentinel” is an enhancement developed by GE’s Technology Team to help lodging professionals welcome their guests with a moderate-temperature room and to help lower cooling costs.

Devices have been added on cord-connected units to protect against injury from unsafe power cords.

See the “Features and Benefits” section for in-depth explanation of these changes and the industry-leading features of GE Zoneline retained from the previous series.

The Deluxe 4100 Series Zoneline models include The “Dry Air 25” models, which remove 25% more moisture than other Zoneline models.

As warm, humid air is pulled through the pre-cool (front) section of the heat pipe, the heat removed from the air is absorbed by the refrigerant, causing the refrigerant to change to a gas and flow to the re-heat (rear) section of the heat pipe. The air leaving the pre-cool section of the heat pipe is cooler and at a higher relative humidity level than the room air. The pre-cooled air is further cooled as it passes through the evaporator, consequently allowing the evaporator coil to remove more moisture.

When the cold air from the evaporator comes in contact with the re-heat section of the heat pipe, the heat that was removed by the pre-cool section is added back to the air

Deluxe Dry Air 25 Models

Cooling With Resistance Heat

• Removes 25% more moisture than standard Zoneline models

• Cools and dries air in less time than standard Zoneline models

• Dry Air is a separate sealed refrigerant system — No mechanical parts — No special maintenance required

• Helps maintain lower relative humidity in rooms

• Maintains comfort at slightly higher room temperatures — Reduces operating costs — Provides comfort without

overcooling

• Corrosion treatment is standard

• Excellent choice for humid climates

• Available in 7,000, 9,000 and 12,000 BTU sizes The Dry Air 25 system, a heat pipe, is a hermetically sealed

heat transfer surface installed in a “saddlebag” configuration around the indoor (evaporator) coil of the Zoneline unit. This coil arrangement will transfer heat from the front coil of the saddlebag to the rear coil without power consumption. This assembly uses R-410A as the refrigerant and is not connected to the regular Zoneline refrigerant circuit.

and the refrigerant in the heat pipe condenses and flows back to the pre-cool (front) section. The air discharged into the room by this process is much drier, creating a more comfortable room condition.

The Dry Air 25 models center around GE’s exclusive use of the patented Dinh® Dehumidifier Heat Pipe from Heat Pipe Technology, Inc. This innovative NASA spin-off technology enables Dry Air 25 to remove 25% more moisture from the air than other leading manufacturers’ packaged terminal air conditioners. This helps maintain room comfort at a higher room temperature, reducing operating costs.

The Dry Air 25 keeps a room cool and dry, and this is the most important benefit when it comes to the occupant of the room—hotel guests, apartment residents, students. In a hot, humid climate, getting away from the humidity is just as important as getting away from the heat, and the Dry Air 25 is the perfect solution. The dehumidification of the Dry Air 25 has been verified by the same AHRI test conditions under which standard units are rated.

Important Notice

Equipment used as a primary source for heating or cooling is an integral part of the building in which it is installed. Proper application is essential for satisfactory performance over a wide range of operating conditions. It is strongly recommended that a professional engineer determine proper application.

If the unit is a replacement unit, its specifications and performance may differ from those of the unit it is replacing. For that reason, we again strongly recommend that a professional engineer determine proper application.

Automatic Emergency Heat

Automatically uses electric resistance heat if the heat pump output is not sufficient to maintain selected room temperature.

Reverse Cycle Heat Pump Defrost System

Standard on all Zoneline 6100 Series heat pumps

Enables heat pump to operate at lower temperatures when other systems switch to more expensive electric resistance heat.

See pages 18 and 19 for discussion of heat pump operation and defrost systems.

High-Temperature Heat Pump Operation Protection

Automatically protects the compressor if heat pump is operated with high outdoor temperatures.

Power to the outdoor fan is turned off if the indoor coil gets too hot during heat pump operation to prevent damage to the compressor.

Quick Heat Recovery – Heat Pump Units

When the unit operation is changed from STOP or COOL to HEAT, the electric resistance heaters are used to warm the room to the thermostat set point. This provides faster room temperature increase for greater guest comfort.

Fan Motors – Permanently Lubricated

All units have two fan motors for quiet operation and maximum operating efficiency.

Motors are permanently lubricated to reduce maintenance and totally enclosed to keep dirt and water out of the motor windings.

Unit Controls

4100 and 6100 Series — touch pad controls with digital

readout of temperature set point

Highly Featured Microprocessor Controls

Microprocessor controls are programmed to interface with the temperature sensors to maximize comfort conditions for the room occupant and provide outstanding features.

Thermistors are used to sense small changes in temperature to give excellent room control and allow the microprocessor to monitor and react to changing conditions.

Electric Resistance Heat Lock-Out

To maximize the savings of the heat pump operation, the Zoneline® heat pumps do not utilize the resistance heater when the outdoor temperature is above 46°F during normal operation. The resistance heat is used in the Quick Heat Recovery feature.

Outdoor Fan

The unit automatically selects the most efficient speed for the outdoor fan. The operating sound level is lower when the outdoor fan can operate in low speed, yet there are situations where it must operate in high speed. The unit changes the fan speed automatically.

Indoor Fan Speed Selections – HIGH/LOW

Unit may be operated in HIGH HEAT or LOW HEAT or HIGH COOL or LOW COOL.

The unit provides the option of selecting either HIGH or LOW speed for Fan-Only operation.

Fan-Cycle Switch – “SmartFan”

Unique “SmartFan” allows unit to operate fan continuously in cooling operation and fan cycle in heating to provide better guest comfort. Eliminates complaint of cold-air draft during the heating season.

Eliminates the need for changing fan-cycle switch seasonally.

“SmartFan” settings are controlled via the auxiliary control setting push button.

Compressor Random Restart

In the event of a power failure, all compressors attempting to restart immediately when power is restored can result in a power surge that can cause another power interruption.

The microprocessors in the Zoneline units have a random restart logic system that prevents all units from starting at the same time.

Rotary Compressor

Provides smoother operation for quiet, dependable service. GE has used rotary compressors since 1961.

Compressor Restart Delay

Zoneline units are designed to provide a minimum of three minutes of compressor-off time to allow refrigerant pressures to equalize before restarting to prevent compressor damage.

Zoneline units are also designed to provide a minimum of three minutes of compressor-run time to prevent room occupant disturbance due to short-cycling of the air conditioner.

Freeze Sentinel

Detects low room temperature and turns on heater to help protect against damage caused by freezing room temperature.

Heater turns on at 41°F and warms indoor thermistor temperature to 46°F and shuts off.

Freeze Sentinel may be turned off by dip switch on auxiliary control.

Heat Sentinel

The property owner may choose to activate the Heat Sentinel feature on the Zoneline unit. If the Heat Sentinel is activated and room temperature reaches 85°F (even when the unit is in the “STOP” setting), the unit will automatically start in air conditioning operation and will shut off when the room temperature reaches 80°F. This will help dehumidify the air and lower high temperatures so the guest will not be entering an extremely hot room.

Indoor Coil Frost Control

Prevents indoor coil from freezing and causing complaints due to lack of cooling. Frost can form on the indoor coil when the unit is operated in cooling when outdoor temperatures are low. The unit automatically shuts the compressor off until the indoor coil temperature warms to the point where frosting will no longer occur.

Trans fer Fan Inter face

24 VAC terminals are provided to operate a relay to control a fan mounted in a wall to move conditioned air into another space. The electrical power for the operation of the transfer fan itself is not provided by the Zoneline unit. Transfer fans and their controlling relays are field supplied.

Electronic Temperature Limiting

Seven independent programmable heating temperature limits and seven independent programmable cooling temperature limits.

Energy Management System Interface with Load-Shedding Option

All units have a switch via the auxiliary control setting to allow the indoor fan to continue operating if the unit is connected to an energy management system that shuts off compressor or heater operation. By allowing the indoor fan to run when the heater or compressor is shut off by the energy management system, the guest is less likely to realize the operation of the unit has been altered. This helps reduce peak energy demand loads without disturbing the room occupant.

Reversible Indoor Air Louvers

Allows air to be directed into room at 40º or 50º angle to provide better air distribution.

Angle is changed by removing room front and screws holding louver in place, and rotating louver section.

FEATURES AND BENEFITS (cont)

Up-Front Air Filters

Two interchangeable up-front filters, easy to remove and reinstall, may be cleaned without opening or removing the room front.

Clean filters by brushing, vacuuming or backflushing under faucet or shower head.

Concealed Manual Vent Control

Open ventilation doors on GE Zoneline® Packaged Ter minal Air Con ditione rs and Heat Pumps allow outside air to enter the room through a screen-covered opening in the weather barrier that separates the indoor and outdoor sections of the unit.

A concealed lever, located along the left side of the unit under the front cover, is used to open and close the vent door.

The 3-position manual vent door control may be closed, partially open or fully open. Positive vent door closure prevents accidental opening and unwanted air infiltration.

CFM ratings at 230 and 265 volts.

For each CFM of air to enter the room, an equal amount of air must be removed through exhaust fans in the bathroom or roof tops. Greater amounts of air will be introduced (from chart shown above) depending on the size of the exhaust fan.

Outside ambient air entering the room through this screened vent opening is not conditioned. This unconditioned air becomes mixed with the conditioned air that is circulated by the indoor fan. This air mixture generates an additional heat load/heat loss that causes the unit to run longer and may translate into higher operating costs.

Zoneline vent openings are not intended to be the source of make-up air for building ventilation systems due to the additional heating or cooling loads generated.

Corrosion Protection (Optional)

4100 and 6100 Series units may be ordered with special protection to better withstand damage from salt air and salt water in seacoast or other corrosive areas.

Corrosion protection is standard on the Dry Air 25 models.

Heat pump units with ICR are not available with corrosion protection and should not be installed in seacoast or other corrosive environments.

Units installed in corrosive areas should use the RAB77 wall sleeve and be examined/cleaned more frequently than normal installations.

Internal Condensate Removal (ICR)

See page 35 for a discussion of the Internal Condensate Removal system available on 6100 Series heat pumps.

Enhanced Dehumidification

Moisture removal is an important function of an air conditioner. People are more comfortable at higher temperatures when the humidity level is relatively low. Air conditioners operate with less energy consumption when the room temperatures are set higher.

The GE Zoneline 4100 Series with the Dry Air 25 heat pipe application removes 25% more moisture than the base 4100 Series unit .

The GE Zoneline Dry Air 25 chassis is the only PTAC available with the application of the patented Dinh® Dehumidifier Heat Pipe under license from Heat Pipe Technology, Inc.

Customers who are using the Dry Air 25 report a freshersmelling room as a result of the lower humidity levels, as well as lower operating costs.

AUXILIARY CONTROL SETTINGS (cont)

Mode 3—Freeze Sentinel/Heat Sentinel

The default settings for Mode 3 are: Heat Sentinel is off Freeze Sentinel is on. When Freeze Sentinel is activated, it automatically provides heat without user interface. This helps to prevent plumbing damage by turning the heater and indoor fan ON at 41ºF and OFF at 46ºF. When Heat Sentinel is activated, it automatically provides cooling without user interface. This helps to prevent an excessively hot room by turning the air conditioner ON at 85ºF and OFF at 80ºF.

NOTE: These functions are active whenever the unit is plugged in, even if the unit is in the STOP position.

Mode 4—Constant ON Fan The default setting for Mode 4 is OFF.

Mode 6—Remote Thermostat – Class 2 The default setting for Mode 6 is OFF. Setting this mode to ON will allow the unit to operate with a Class 2 Remote Control Wall Thermostat.

Mode 7—Duct Mode The default setting for Mode 7 is OFF. This setting is used when the unit is installed using a duct adapter kit. If the unit is ducted, the Duct Mode needs to be set to ON. This increases the fan speed to ensure proper circulation.

Mode 8—All-Electric Heat (AZ6100 only) The default setting for Mode 8 is OFF. This electric heat option functions only on the 6100 model. When this option is ON, heat pump operation is locked out, causing the unit to provide only electric resistance heat.

Mode 9—Heat Boost (AZ6100 only) The default setting for Mode 9 is OFF. When Heat Boost is ON and outer temperatures are between 25ºF and 46ºF, heat pump-only operation is locked out. This setting is used to provide supplementary heat to the heat pump operation by electric resistance heat in conditions where the heat pump-only operation is not sufficient to maintain a consistent, comfortable room temperature.

NOTE: Heat Boost option should NOT be used with remote thermostat operation. This will cause the unit to switch to resistance heat when the outdoor temperature is 46ºF.

CENTRAL DESK CONTROL

Unit #2

Unit #1

Unit #3

CDC Terminals

on Zoneline unit

Some installations may want to govern the ability of the unit to operate from a control device remote to the unit or even remote to the room in which the unit is located. The general term given to systems such as this is Central Desk Control (CDC). The most common installation of this type of system is a switch mounted at the registration desk and, upon guest check-in, a button is pushed or a switch is moved to allow the air conditioner to operate. Likewise, when the guest checks out, the device is put into the “OFF” position so the unit will not operate while the room is vacant.

It is not necessary that the controlling device be located at a central desk to employ a device that will control the unit operation. For instance, in some resort areas, devices are connected to sliding glass doors and opening the door causes a contact to close, turning the air conditioner off. This prevents energy being wasted by operating the air conditioner when warm, humid air is entering the room. Some systems operate by motion sensors or heat-sensing detectors mounted in the room. These types of systems determine occupant presence in the room and allow the unit to operate; if no one is in the room the device signals the air conditioner to turn off.

Zoneline

models offer load-shedding capabilities on units connected to Central Desk Control systems. For more information on the models’ load-shedding feature, see page 11.

There is a wide variety of devices available, each with its own benefits and constraints. While GE does not offer components that are external to the unit for a Central Desk Control system, GE Zoneline units are compatible with most CDC and energy management systems. Zoneline units

provide a 24 VAC circuit that powers the Central Desk Control system and no external power is needed.

All Zoneline 4100 and 6100 Series units are compatible with simple on/off 2-wire Central Desk Control systems. Consult with the provider of the energy management system to be sure it is compatible with GE Zoneline units. Zoneline units have standard connectors factory-installed to provide a CDC interface that permits the unit to be connected to most of the energy management systems. The devices connected to the Zoneline units require no power supply or transformers external to the unit.

Important CDC Comments (all series applicable)

4. Recommended wire size must be followed as a minimum requirement.

Wire Size #AWG Maximum Allowable Length

#22 600 Ft. #20 900 Ft. #18 1500 Ft. #16 2000 Ft.

Freeze Sentinel and Heat Sentinel remain operational when the unit is connected to a CDC system. Even if the unit is turned “OFF” at the central location, if the sensor at the unit detects the low or high limit temperature, the unit will automatically turn on until it reaches the preset shutdown temperature (46°F heating, 80°F cooling).

Connecting the Zoneline unit to a CDC system does not eliminate the ability to connect the unit to a remote thermostat. Once the circuit is “opened,” and control of the unit removed from the CDC system, the selected controls—either the unitmounted control or the remote thermostat—govern the operation of the unit.

Please see page 57 for installation recommendations for the Central Desk Control wiring.

CDC Terminal Location and Typical Wiring

See page 16 for location of CDC terminals on unit.

1. When the switching device closes the circuit of the CDC conductors, the unit operation stops.

2. Do not use a common bus (at the unit or at the switch panel) in the wiring. Both wires comprising the circuit must connect to the unit connectors and to the controlling switch. Running one wire from one unit to another unit is common busing and may damage internal components or cause erratic operation of the system.

3. A 24-volt transformer is contained within the Zoneline unit. No external voltage may be applied to the unit through the CDC terminals. (Voltage on the CDC conductors is 24 volt s AC.)

In some installations, control of the operation of the unit at a location remote from the unit itself may be desired. A unit mounted high in the wall or over a door, for instance, where the unit-mounted controls are inaccessible, can be connected to a wall-mounted thermostat. Other installations may use remote thermostat control for design or performance enhancement. The unit is connected to the thermostat by low-voltage wiring which permits the operation of the unit to be selected and the temperature sensed at the thermostat.

Important Notes: Remote thermostat wiring should NOT be run through the wall case. Thermostat wiring should exit the wall below the unit and enter the unit between room cabinet and chassis. Wire molding may be used to hide thermostat wiring. If a sub-base is used, the thermostat wiring may be concealed by the sub-base. Thermostat wiring should NOT be run parallel to line voltage wires since induced current may cause erratic operation.

All Zoneline

4100 and 6100 Series units are adaptable to Class 2 remote low-voltage thermostats. The only additional field-supplied components are the remote thermostat and wiring necessary to connect it.

The controls on the unit are not functional when the remote control function is used.

RAK806 Universal Control Cover Label

When a Zoneline unit is using a remote thermostat control, the RAK806 Universal Control Cover Label is recommended. The RAK806 is only available in a package of 10 labels. The label is placed over the control panel to direct the user to the wall thermostat for operation of the Zoneline unit.

The remote thermostat-Class 2 option (Mode 6 in the auxiliary control setting) must be turned ON to enable remote thermostat control. Refer to installation instructions packaged with the chassis.

Please see page 57 for installation recommendations for the remote thermostat wiring. Compatibility of other thermostats considered for use with GE Zoneline units is the responsibility of the customer.

The control voltage on the remote control conductors is 24 volts AC. The AC voltage may not be compatible with some solid-state thermostats.

The fan speed for the 4100 Series in remote thermostat operation is selected by the connection of the fan wire from the thermostat to either the HIGH or LOW terminal on the unit. See the sketch of the unit terminals below for the location of the HIGH and LOW fan-speed terminals. Operating the unit in low fan speed reduces the operating sound level of the unit.

Freeze Sentinel and Heat Sentinel remain operational if the unit is connected to a remote thermostat. The unit may be connected to a Central Desk Control (CDC) system and controlled with a remote thermostat when the CDC system has the unit in operation. See page 15 for additional information on the CDC system.

Unit temperature-limiting settings are not functional when unit is connected to a remote thermostat.
