The Zoneline® 2900, 3900 and 5800 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.

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 2900 Series Zoneline Models Includes 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, the relative humidity increases 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 and

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. This coil arrangement will transfer heat from the front coil of the saddlebag to the rear coil without power consumption. This assembly uses R-22 as the refrigerant and is not connected to the regular Zoneline refrigerant circuit.

the refrigerant in the heat pipe condenses and flows back to the indoor coil. The air discharged into the room by this process is much drier, creating a more comfortable room condition.

The Newest Innovation from GE

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 the heat, and the Dry Air 25 is the perfect solution. The dehumidification of the Dry Air 25 has been verified by the same ARI test conditions that standard units are rated under. A list of customers using Dry Air 25 is available from GE.

Unit Controls

2900 and 3900 Series — touch pad controls for temperature

and operation selection. 5800 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.

Reverse Cycle Heat Pump Defrost System

Standard on all Zoneline 3900 and 5800 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.

Unit Diagnostics

The 5800 Series has a dip switch that activates each of the various components of the unit to operate briefly. This enables the technician to determine if individual components are functioning properly.

Service Indicator

On the 5800 Series, if the microprocessor detects a compressor malfunction, the digital temperature display will blink. If the malfunction occurs during cooling operation, the indoor fan will continue to operate. If the compressor malfunctions in heating mode, the unit will automatically switch to resistance heat to maintain room temperature set point. GE Service should be called to check the Zoneline.

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.

2-Speed 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.

Automatic Emergency Heat

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

Features and Benefits

Fan-Only Setting – HIGH/LOW

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 continuous in cooling operation and fan cycle in heating to provide better guest comfort. Eliminates complaint of cold air draft during heating operation.

Eliminates need of changing fan-cycle switch seasonally. “SmartFan” settings are controlled by two dip switches on

auxiliary control panel.

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 Zonelines have a random restart logic system that prevents all units from starting at the same time.

Rotary Compressor

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

Compressor Restart Delay

Zonelines 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.

Zonelines 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. If the Heat Sentinel is activated and room temperature reaches 85°F while 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.

Transfer Fan Interface

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. 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. Eliminates need to reset the limits seasonally.

Energy Management System Interface with Load Shedding Option

All units have a switch on the auxiliary control panel 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

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.

Easy Clean Air Discharge Area

2900 and 3900 Series units have an out-of-sight vertical

protective screen over the indoor fan. This allows easy cleaning of air discharge area by simply removing room front and wiping clean.

There is no screen directly below discharge louver to trap unsightly dirt and debris where it may be seen by room occupant.

Concealed Manual Vent Control

The 3-position manual vent door control may be closed, partially open or fully open.

CFM ratings at 230 volts and 265 volts. Greater amounts of air will be introduced if the room has an

exhaust fan. An open vent door brings unconditioned outdoor air into the

room, increasing heating and cooling costs. Positive vent door closure prevents accidental opening and

unwanted air infiltration.

Corrosion Protection (Optional)

2900 and 3900 Series units may be ordered with special protection to better withstand damage from salt air and salt water in seacoast areas.

Corrosion protection is standard on the 5800 Series and on Dry Air 25 models.

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

Units installed in corrosive areas should be examined and cleaned more frequently than normal installations.

Internal Condensate Removal (ICR)

See page 34 for a discussion of the Internal Condensate Removal system available on 3900 and 5800 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® 2900 Series with the Dry Air 25 heat pipe application removes 25% more moisture than the base 2900 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.

CDCTerminals

onZoneline

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. 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 10.

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 (CDC) system, GE Zonelines are compatible with most CDC and Energy Management systems. Zonelines provide a 24 VAC circuit that powers the Central Desk Control system and no external power is needed.

All Zoneline 2900, 3900, and 5800 Series units are compatible with simple on/off 2-wire Central Desk Control systems. Consult with the provider of other energy management systems to be sure they are compatible with the GE Zoneline. Zonelines 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™ remains 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 temperature, the electric resistance heaters and the fan will automatically turn on.

Connecting the Zoneline 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 unit mounted control or the remote thermostat - govern the operation of the unit.

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

Unit Operational

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

2. Do not use a common buss (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 bussing and may damage internal components or cause erratic operation of the system.

3. A 24-volt transformer is contained within the Zoneline. No external voltage may be applied to the unit through the CDC terminals. (Voltage on the CDC conductors is 24 volts 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 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 2900, 3900 and 5800 Series units are adaptable to Class 2 remote low-voltage thermostat. 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.

Resistance Heat Models

The Zoneline 2900 resistance heat units may be connected to a single-stage thermostat designed for use with cooling with electric heat systems. GE offers three thermostats compatible with the 2900 Series unit.

The AC voltage may not be compatible with some solid-state thermostats.

The fan speed for the 2900 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 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™ remains 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 14 for additional information on the CDC system.

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

Heat Pump Models

The Zoneline® 3900 and 5800 Series heat pump units may be connected to a single-stage cooling/two-stage heating thermostat designed for use with heat pump systems. GE offers 2 thermostats compatible with the 3900 and 5800 series units:

RAK148D1 — solid-state digital manual changeover thermostat requiring 6 connection wires.

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

The control voltage on the remote control conductors is 24 VAC. The Class 2 Mode Switch, dip switch #4 on the auxiliary control

board on both the 3900 series and the 5800 series, must be set to the ON/UP mode to enable remote thermostat control. Refer to installation instructions packaged with the chassis.

The fan speed for the 3900 and 5800 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 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.

When connected to a remote thermostat, the indoor air temperature sensing is shifted from the unit to the remote thermostat. For this reason, the units will operate slightly differently when connected to a remote thermostat. The following chart shows the unit operation when connected to a remote thermostat.

Temperature Boost option should not be used with remote thermostat operation since this will cause the unit to switch to resistance heat when outdoor temperatures are below 46ºF.

Heat Pumps and Energy Savings

• GE Zoneline® Heat Pumps are designed to provide

cost-efficient heat pump operation while monitoring room conditions to maintain comfort.

The units employ a logic system monitoring both outdoor and indoor temperatures to determine the heat source, thus increasing energy savings by operating longer in the heat pump mode.

Heat pumps save energy and cost less to operate than units with electric resistance heaters as the only heat source. Just as the EER of an air conditioner is an indication of the efficiency of the unit, COP (Coefficient of Performance) is the indication of the efficiency of the heat pump. This relative efficiency of a heat pump compares the unit to electric resistance heat. If a unit has a COP of 3.0, it means the unit will produce three times as much heat at rating conditions for the same electrical input wattage used for electric resistance heat.

The compressor is used in heat pump operation just as in air conditioning operation. In heat pump operation, the hot refrigerant gas is directed to the indoor coil rather than to the outdoor coil. Room air that circulates over the indoor coil gains heat from the coil rather than losing heat to the coil as during cooling operation.

As the outdoor temperature falls, the heat pump is able to extract less heat from the outdoor air to raise the temperature of the indoor air. For this reason, all packaged terminal heat pumps also have electric resistance heaters as backup to heat pump operation. At some point, the heat pump is unable to provide sufficient heat to adequately warm the room. Many Packaged Terminal Heat Pumps cease heat pump operation and change to more expensive resistance heat at some pre-determined outdoor temperature to compensate for the inability of the heat pump to maintain room temperature. This point, called the “switchover point,” is usually at an outdoor temperature where savings from heat pump operation may still be realized, if the unit is designed to maintain room comfort at the lower outdoor temperatures.

Balance Point

An important consideration of the selection of a heat pump unit is the “balance point” of the installation. Virtually every room is unique — with different insulation — different sizes and types of windows — different types of construction — different directional exposures. All of these variables, as well as geographical location, must be considered in order to determine the balance point, the point at which the heat pump is unable to produce enough heat to compensate for the heat loss of the room or area being heated. For these reasons a consulting engineer should be engaged to calculate the heat loss and specify the heat pump unit required.

GE offers two series of Zoneline Heat Pump units — the 3900 Series with Standard Microprocessor controls and the 5800 Series with Highly Featured Microprocessor controls — and both series react to the indoor temperature as well as the outdoor temperature in determining the heat source to provide comfortable room conditions and energy savings. This determination of the heat source based on the indoor temperature helps provide a more comfortable room.
