The Newest Innovation from GE...
The Dry Air 25 Models center
around GE’s exclusive use of the
patented Dinh
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 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.

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 this 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. See page 42.

Introduction
This manual is designed to provide product, performance
and application information to our customers and their
architects and engineers for use in selection and design of a
zonal comfort control system utilizing GE Zoneline
Packaged Terminal Air Conditioners (PTAC) and
Packaged Terminal Heat Pumps (PTHP). GE Zoneline
PTACs and PTHPs are self-contained units designed for
through-the-wall installations in hotels, motels, apartments,
hospitals, nursing homes and add-on rooms.
Zoneline models provide individual room or zone control in
both cooling and heating operation. There is a model for
practically every application, ranging in cooling capacities
from 7,000 to 15,000 BTUH and heating capacities from
6,400 to 14,500 BTUH in heat pump operation. A choice of
electric resistance heat is available ranging from 2.55 KW to
5.0 KW on 230 volt units and from 1.7 KW to 5.0 KW on 265
volt units.
The Zoneline offers a two tier lineup; the Deluxe Line - the
2200 Series with electric resistance heat, the Dry Air 25
Models with enhanced dehumidification for hot and humid
climates and the 3200 Series heat pump; the Premium Line 5200 Series heat pump.
The Deluxe Line units use standard microprocessor controls
with a two fan motor design. Zoneline 2200 Series
(including the Dry Air 25 Models) Packaged Terminal Air
Conditioners and 3200 Series Packaged Terminal Heat
Pumps offer as standard many of the features found on
competitive units only as added cost options. Features such
as Freeze Sentinel
Low Voltage Remote Thermostat Control compatibility*,
compressor restart protection, random restart after power
failure, mechanical temperature limiting, are standard on
the Deluxe Line. The Deluxe Line also provides some
features not found, even as options, on some competitive
units. Features such as Indoor Coil Frost Control to enable
the unit to operate in the cooling mode under low outdoor
ambient conditions, and a two-stage thermostat on the 3200
Series Heat Pump unit helps maintain a comfortable room
for the occupant while saving energy for the property owner.
The Deluxe Line units also offer cooling with electric heat
and heat pump efficiencies that make them an outstanding
value; Deluxe represented by low operating cost - Deluxe
represented by the standard features - and Deluxe
represented by the competitive initial cost.
The Premium Line units are highly featured micro-processor
controlled and have separate indoor and outdoor fan
motors. The 5200 Series Packaged Terminal Heat Pumps
offer as standard all the features found on the Deluxe Line
units - Freeze Sentinel
compatibility*, Low Voltage Remote Thermostat Control
compatibility*, and Indoor Coil Frost Control - plus the
added features made possible through the use of electronic
controls; features such as automatic fan speed control,
staged heating, electronic temperature limiting, high
ambient heat pump operation, and unit diagnostics. The
5200 Series Heat Pump units also have an exclusive feature
in PTHP units - Selectable Full Time or On Demand
Simultaneous Operation of Heat Pump and Supplemental
Resistance Heat - which provides the most advanced heat
pump operation to assure room occupant comfort while
providing the energy savings of a heat pump. The active

Chassis Features and Benefits
• Consistent Physical Dimension
Fits all existing GE Zoneline wall cases (see page 21)
The GE Zoneline was first introduced into the marketplace
in 1961. Since that time, efficiencies and features have been
greatly improved. In spite of these improvements, GE
recognizes that some features should stay the same. That’s
why any recently-manufactured Zoneline chassis can be
installed in any Zoneline wall case, regardless of age. The
original Zoneline wall case was 42" wide by 16" high, the
same dimension of the wall case today, enabling a new
Zoneline to be installed in an existing 42" by 16" wall case
without the need for extensive modifications. Note: Existing
outdoor grille may need to be replaced or modified. (see
page 41)
• Controls Conveniently Located, Easy to
Operate
Reduces uncertainty of operation for room occupant
(see page 8)
Zoneline controls are mounted on the top of the unit,
angled for better visibility and access. The controls are
under a door for appearance enhancement. The 2200 Series
and the 3200 Series have rotary controls for temperature
and operation selection. The 5200 Series units have Touch
Pad controls. An optional locking control door, RAK8022 is
available.
• Universal Heater - Premium Models
Resistance heat output of unit can be matched to the heating
demands of the particular area (see pages 38, 39 and 53)
Often, the choice of a Zoneline heater is influenced by the
location of the room it is intended to heat. For instance, the
end room in a wing or the corner rooms on top floors will
have a higher heat loss than interior rooms having only one
wall exposed to the outdoors. These higher heating
demands are often compromised for the sake of equipment
consistency. In many instances, all rooms are sized higher to
accommodate the minority of the rooms having the higher
heat loads. Naturally, such sizing policies result in increased
total connected current load, and quite often, higher overall
energy costs.
In response to this customer need, each Premium Model is
equipped with three built-in heaters and, when connected
with the proper Universal Power Connection Kit (UPC), can
be closely matched to the heating requirements and circuit
ampacity of a specific room. In addition, this feature allows
maintenance personnel to interchange units in rooms
having different heating requirements.
• Discreet Heater - Deluxe Models
Resistance heat output of unit can be matched to the heating
demands of the particular area (see pages 38, 39 and 53)
Deluxe Models offer cost-conscious customers factoryinstalled discreet heaters. The ninth character in the Deluxe
Line model number represents the specific wattage of the
heater. A Deluxe Model chassis may be ordered with a
custom resistance heater in any one of the following
KW ratings:
230/208 Volts: 2.55/2.09 KW; 3.45/2.82 KW;
5.00*/4.09 KW
265 Volts: 2.00 KW; 3.00 KW; 4.00 KW; 5.00 KW*

• Reversible Discharge Louver
Enables discharge air flow to be changed to maximize air
distribution and comfort (see page 42)
Reversible louver section on all units.
The discharge louver section comes from the factory set to
exhaust air into the room at an angle of 50° off vertical. The
louver section may be reversed to provide a discharge angle
of 40° off vertical with the simple removal of seven screws,
rotating the louver section end to end, and reinserting the
screws. The screws are located on the inside of the room
cabinet.
• Fan Cycle Switch
Allows indoor fan to be set to run continuously or cycle on and off
with compressor and heater
Setting the fan to cycle off and on with the compressor or
heater results in some energy savings when the fan is not
operating. The amount of energy savings will vary
depending upon many factors.
2200 & 3200 Series: The room cabinet must be removed to
gain access to the fan cycle switch. The switch is set in the
DOWN/OFF position at the factory to provide continuous
fan operation in the cool and heat modes. Leaving the
switch in the continuous setting allows circulation of room
air and will result in a more uniform temperature
throughout the room.
The fan switch on the Deluxe Models is located on the
Auxiliary Control Panel. It is switch number two. Setting the
switch in the UP/ON position will cause the fan to cycle on
and off with the compressor or resistance heater. In humid
climates, operating the unit in “FAN CYCLE” may result in
better dehumidification.
5200 Premium Model: The fan cycle switch is located
behind the room cabinet. The switch is set in the DOWN/
OFF position at the factory to provide continuous indoor fan
operation in the cool and heat modes. Leaving the switch in
the DOWN/OFF setting allows continuous circulation of
room air and will result in a more uniform temperature
throughout the room. In humid climates, operating the unit
in “FAN CYCLE” may result in better dehumidification.
The fan switch on the Premium Models is located on the
Auxiliary Control Panel. It is switch number nine. Setting
the switch in the UP/ON position will cause the fan to cycle
on and off with the compressor or resistance heater.
*NOTE: 5.0 KW heaters not available on 7,100 BTUH units.

Chassis Features and Benefits
• Automatic Frost Control
Permits unit to be operated in cooling mode with low outdoor
temperatures
Occasionally, cool outdoor temperatures and high indoor
humidity conditions will cause frost to form on an air
conditioner’s indoor coil. When this occurs, the excessive
frost restricts air flow and decreases cooling performance.
GE Zoneline’s Automatic Frost Control detects when frost is
forming and shuts off the compressor to prevent component
damage. The
unit restarts
automatically
when the frost
has melted. This
feature enables a
room occupant to
select cooling in
spite of low outdoor
temperatures.
• Weather Protected Electrical Components
Extends life of electrical components
Outdoor conditions may shorten the life expectancy of
electrical components such as capacitors and relays. To the
extent possible, all electrical components are located on the
indoor side of the weather barrier (the sheet metal
component separating the indoor side and the outdoor side
of the unit) to protect them from the outdoor elements.
• Corrosion Treatment (Optional)
Helps extend the life of the unit in corrosive environments
An air conditioner installed close to a seacoast or highly
corrosive industrial environment, where acids or salts are in
the atmosphere, will not have the life expectancy of a unit
installed elsewhere. To help extend the life of a Zoneline
installed in these areas, steps are taken to make the unit less
susceptible to corrosion. For example, selection of noncorroding materials, a process of protecting metal parts by
galvanizing and an electro-deposited paint system, all help
retard corrosion. In addition, the aluminum fins on the
outdoor coil are specially treated to extend their
operating life. (Standard on Dry Air 25 Models)
All GE Zonelines can be ordered corrosion treated except
3200 Series Heat Pump units with Internal Condensate
Removal (ICR) System, 265V 2KW Heater Models, 5200
Series Heat Pumps or 2200 & 3200 Series 5KW Heater
Models. Never install a unit with ICR in a seacoast or
corrosive environment. Units installed in corrosive
environments should be examined and cleaned regularly.
• Weather-Resistant “Superseal”
Minimizes air and water infiltration through the unit
When the GE Zoneline is properly installed in an
undistorted GE Zoneline wall case, the air infiltration
through a unit without ICR is a maximum of seven cubic
feet per minute with a 25 mile per hour wind velocity. Units
with ICR have a maximum of ten cubic feet per minute with
the same conditions. The air infiltration test is conducted in
accordance with ASTM E283-91. The ARI specification for
air infiltration for a unit the physical size of the Zoneline is
19 cubic feet per minute.
Unit also meets ASTM E331-86 (Hurricane Test) which
specifies no water can enter through the unit during 15
minute exposure to rainfall at the rate of eight inches per
hour with 63 mile per hour wind velocity.
• Ventilation Control
Hidden controls help prevent unauthorized selection of outdoor
air ventilation - Saves energy
Zoneline chassis are capable of introducing up to 70 CFM of
fresh air into a room. This feature allows maintenance
personnel to “freshen” a room and reduce odors caused by
stale indoor air.
The vent door control is located on the left side of the
chassis behind the room cabinet and out of sight of the
room occupant. Hiding the vent control from the room
occupant ensures that it cannot be changed from the
condition desired by the building management. This is
important because an open vent door introduces
unconditioned air into the room. The additional heat load
causes the unit to operate longer and that translates into
higher operating costs! In warm humid climates the
introduction of outdoor air
may allow excessive
moisture (water vapor) to
enter the room. If the room
air reaches a humidity level
above the “Dew Point” of
the cold discharge air, the
moisture in the room air
will condense into visible
droplets. This condition is
often referred to as “the
unit is producing “Fog, or Fogging.”
• Easy Access Air Filters
Two up-front filters are removable from top of unit without
removing room cabinet
A clean filter is essential for good air conditioner
performance and longer life. A dirty filter reduces air flow
which results in higher energy consumption. GE has made
filter cleaning an easy task! Some packaged terminal air
conditioners or heat pumps which require removal of the
room cabinet or a “blind positioning” of the filter under the
unit, the up-front filters on the GE Zoneline are conveniently
accessed by simply pulling them up from the top of the room
cabinet. This feature reduces maintenance time and helps
keep the units operating in peak condition. Because the
filters are so easy to
remove, it also
increases the
likelihood that
cleaning will occur
on schedule.

Chassis Features and Benefits
• Permanently Lubricated Fan Motors /
Indoor and Outdoor Air Movers
Designed for low maintenance and optimum value, efficiency, and
performance
Zoneline units have permanently lubricated fan motors. Fan
motors that require oiling on a periodic basis generate an
additional maintenance cost for removing, oiling, and
reinstalling the units in the wall case. The Permanent Split
Capacitor (PSC) motors used in Zonelines are permanently
lubricated and totally closed to prevent dirt and foreign
material from entering the motor and shortening its life.
2200 and 3200 Series units use squirrel cage indoor blower
and propeller type outdoor fan. The Zoneline 2200 Series
Packaged Terminal Air Conditioner (PTAC) and the
Zoneline 3200 Series Packaged Terminal Heat Pump
(PTHP) use two fan motors to operate the indoor blower
and the outdoor fan. A squirrel cage blower on the indoor
side combined with 2 discharge ports provide balanced
temperature air flow and quiet operation. The outdoor fan
is a molded polymer propeller type fan. The outdoor fan
motor does not operate in FAN ONLY or in resistance heat
operation on 2200 series.
5200 Series units employ a cross-flow indoor blower and
propeller outdoor fan. The Zoneline 5200 Series PTHP has
two fan motors. A quiet, efficient, tangential cross-flow
blower is driven by the indoor fan motor. The outdoor fan is
a molded polymer propeller type fan driven by a separate
motor. The outdoor fan motor does not operate in FAN
ONLY.
• Rotary Compressor
Fewer moving parts for quiet, dependable service
GE introduced the use of rotary compressors in their air
conditioners in 1957. Today, rotary compressors are the
quiet and efficient compressor choice for Packaged
Terminal Air Conditioners and Heat Pumps.
• Control Devices
Designed to maximize value and room comfort
All Zonelines have electronic thermostats. Electronic
thermostats utilize a thermistor to sense room temperature.
A thermistor is a resistor that changes value (resistance)
with a change in temperature. The resistance changes
rapidly and predictably with temperature. Interfaced with a
microprocessor in the Zoneline 2200, 3200 and 5200 series
units, the thermistor can sense temperature changes as small
as 0.2°F. in staged heating and less than 1.0°F. in the
heating and cooling modes.
• Freeze Sentinel
Automatically turns on resistance heaters to help prevent damage
from freezing temperatures

• Compressor Restart Protection
Electronically locks-out compressor operation to allow system
pressure equalization
Compressor Restart Protection is standard on all Zoneline
Units, and prevents the compressor from starting before
sufficient time has elapsed for the internal refrigerant
pressures to equalize. This situation could occur if a room
occupant turns the unit back on too quickly after shutting it
off - or if the thermostat is adjusted immediately after the
compressor has shut off. By locking out the compressor until
the pressures have equalized, the thermostat prevents the
compressor overload from tripping. That in turn, alleviates
any anxious moments for the room occupants while they
wait for the overload to reset.
• High Ambient Heat Pump Operation
Protection
Automatically protects the compressor during heat pump
operation.
High Ambient Heat Pump Protection is standard on the
3200 and 5200 Series Zoneline.
If a heat pump is operated in the HEAT mode when
outdoor temperatures are at a point where heat is not
normally required, the compressor may cycle on the
overload protector. An electronic sensor monitors indoor
coil temperature and terminates outdoor fan operation
when high temperatures are reached and resumes when the
indoor coil temperature drops.
• Emergency Heat Switch
The 3200 and 5200 Series Models are equipped with an
emergency heat switch that overrides the heat pump feature
and energizes the electric resistance heaters. With the
emergency override dip switch set, the heat pump function
is locked out and the unit operates as an electric resistance
heat model. Operating the unit in resistance heat results in
higher utility costs.
12
Chassis Features and Benefits
• Temperature Limiting
Saves energy by controlling temperature extremes
Temperature limiting restricts the operating range by
preventing the controls from being set to energy wasting
extremes. 2200 and 3200 Series units
have mechanical temperature limiting.
Mechanical temperature limiting
involves positioning screws, located
under the control panel, to restrict the
movement of the temperature control
knob. Each location will reduce the
operating temperature extreme by
about 2.5°F.
Mechanical temperature limiting is
“dependent” type limiting, which means
limiting the lowest cooling temperature
will not permit heating selections below
that point, and limiting highest heating
temperature will not permit cooling selections above that point.
Mechanical temperature limiting is detectable to the user
since the control knob will not turn to its extreme settings.
5200 Series units with highly featured microprocessor
controls have electronic temperature limiting. The
temperature is limited electronically. The display is limited
to the temperature that the unit can attain. If the
temperature limits have not been programmed, the full
range from 60°F to 85°F can be changed by the user. It also
allows the heating and cooling temperature limits to be set
independently.
Temperature limiting can reduce energy costs by limiting
the lowest cooling temperature and the highest heating
temperature. Electronic Temperature Limiting is achieved
by setting the first six small vertical dip switches in a strip of
14 mounted on the auxiliary control circuit board. The first
three (1 thru 3) are used to select cooling range limits and
the next three (4 thru 6) are used to select heating range
limits.

• Compressor Malfunction Indicator
Service indicator on control panel signals a possible compressor
problem
The Service Indicator is standard on the Zoneline 5200
Series. Should the compressor fail to start after four
attempts, with a three-minute pause between each attempt,
the temperature display will blink to alert the user or the
maintenance staff that the unit needs service. The 5200
Series heat pump will continue to provide heat for the room
with the electric resistance heaters. However, the unit should
be serviced as soon as possible so it may be returned to
economical heat pump operation.
• Auto Fan Speed Control
Automatically selects fan speed necessary for better comfort and
quieter operation
Auto Fan Speed Control is standard on Zoneline 5200 Series.
The units have three fan speed selections - HIGH, LOW and
AUTO
changed by
pressing the
FAN touch
control. When
the AUTO
setting is
selected, the
indoor crossflow blower
and the
outdoor fan
automatically switch to LOW fan speed when the room
temperature is within 1.8°F. of the selected setting. This
feature reduces operating sound level in both the cooling
and heating modes by changing the fan speed to its lowest
operating level.
If the unit is connected to a remote thermostat, Auto Fan
Speed Control is not functional and, if the fan speed is set at
AUTO, the unit will operate in HIGH fan speed. However,
LOW fan speed may be selected by changing setting of dip
switch B (11th from the left) on auxiliary control panel to
the UP/ON position.
Zoneline 5200 Control Panel
• Random Restart
Prevents extreme amperage draw on main circuit after power
failure
Automatic Random Restart is standard on all Zoneline units.
When power is restored after an outage, several compressors
starting simultaneously can cause a power drain. The
Random Restart feature prevents all units from restarting at
the same time. Each unit will restart in a period of three
minutes and three seconds to three minutes and twenty
seconds after the power is restored to the units. The circuit
design adds a random variance to prevent all of the units
from restarting at precisely the same time, and allows time
for the internal pressure of the refrigerant system to equalize
so the compressor will start and not trip the overload.
13
Chassis Features and Benefits
• Unit Diagnostics
Switch on auxiliary control panel cycles unit’s components to help
detect malfunction
Unit Diagnostics is standard on the Zoneline 5200 Series.
When the Unit Diagnosis switch, located on the auxiliary
control panel, is turned to the “ON/UP” position, the unit
cycles through the operation of various components. The
operation of the main heater, supplemental heater, indoor
fan motor (both high and low speeds), and the compressor
are checked.
The reversing valve is also cycled through the cooling and
heating modes. The Unit Diagnostics feature helps a
servicer identify a malfunctioning component thus reducing
service call time. During the Diagnostic Cycle a “d” will be
displayed in the temperature display.
• Quick Heat Recovery (5200 and 3200 Series)
Provides faster room comfort conditions in heating operation
As the name implies, Quick Heat Recovery activates
whenever the heating selection has been initialized. This
feature provides electric resistance heat whenever the unit is
turned on in a heating mode or switched from any other
mode to heating. Its purpose is to quickly bring a room to
the desired temperature by using electric resistance heaters.
This feature minimizes any concerns a room occupant
might raise about the discharge air temperature of a heat
pump and the time it might take to bring the room up to
temperature. Quick Heat Recovery is functional when
connected to a Central Desk Control system.
• Electric Resistance Heat Lock-Out
(5200 Series Only)
Saves energy during milder temperature conditions
The electric resistance heaters are disabled on the 5200
Series whenever the outdoor temperature is above 46°F. This
feature decreases operational costs by automatically
maintaining energy-efficient heat pump operation during
conducive weather conditions. However, The Quick Heat
Recovery Feature (described above) is still operational.
• Load Shedding Option (RAKOIM required)
Provides installation flexibility
Load shedding may be accomplished on any Zoneline
connected to an Energy Management Control System.
Premium Models: The Load Shedding dip switch (switch
“C” (12th from the left), located on the auxiliary control
panel) must be set in the ON/UP position. Deluxe Models:
Load Shedding may also be achieved by setting switch (5th
from the left), located on the auxiliary control panel) to the
ON/UP position.
Load Shedding allows building management to gain control
of the Zoneline’s compressor and heater without affecting
fan operation. Under these circumstances, the fan will
operate whenever the Zoneline’s thermostat closes. Normal
operation is restored when the Energy Management Control
System relinquishes control.
• Auxiliary Controls
The switches on the Zoneline models can be set to provide
operational control to the unit that is not available to the
tenant of the room. It is the owners responsibility to position
these switches to provide the unit operation they desire.

• 2200 Series Enhanced Dehumidification
The Newest Innovation from GE...the Dry Air 25
The Dry Air 25 Models center around GE’s exclusive use of
the patented Dinh
Technology, Inc. This innovative NASA spin-off technology
enables the Dry Air 25 to remove 25% more moisture from
the air than other packaged terminal air conditioners.
The Dry Air 25 system, Heat Pipe, is a hermetically sealed
heat transfer surface that is saddle-bagged around the
indoor coil (evaporator) of the Zoneline. This coil
arrangement will transfer heat from one coil to another
without power consumption. This assembly uses R-22 as the
refrigerant and is isolated from the regular Zoneline
refrigerant circuit.
As warm humid air is pulled through the pre-cool section of
the Heat Pipe, the heat removed from the air is absorbed by
the refrigerant, causing the refrigerant to boil. As the precooled air passes through the Zoneline evaporator, the air is
further cooled (colder than it would be normally), removing
25% more moisture than other packaged terminal units.
As the cold air passes through the re-heat section of the Heat
Pipe, the refrigerant condenses and the liquid flows back to
the pre-cool section to be re-heated again. The air
discharged into the room by this process is much drier,
creating a more comfortable room condition.
The Dry Air 25 is perfect for high humidity climates.
Available on 7000, 9000 and 12000 BTU models.

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 as an
electric resistance heater.
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 Heat Pump units - the 3200 Series
with Standard Microprocessor controls and the 5200 Series
with Highly Featured microprocessor controls - and both
Series utilize multi-stage thermostats to 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.
• Heat Pump Operation — Zoneline 3200 Series
Switchover to resistance heat is determined by indoor temperature
differential and outdoor coil temperature
The Zoneline 3200 Series heat pumps are Standard
Microprocessor controlled units. A solid state thermostat
control is used to measure the room temperature and
compare it to the temperature selected with the “TEMP”
control knob. A temperature sensor is in contact with the
outdoor coil to monitor the outdoor coil temperature
during heat pump operation.
The switchover point of the 3200 Series heat pump is
determined by the outdoor coil temperature or the indoor
air temperature. When the outdoor coil temperature is
above 9°F. (which corresponds to approximately 25°F.
outdoor air temperature), the unit attempts to provide
sufficient heat through heat pump operation to satisfy the
selected temperature setting.
A two-stage thermostat monitors the indoor room
temperature and determines if the heat pump output is
adequate to maintain comfort conditions. As long as the
heat pump output maintains the room temperature within
2.7°F of the set point, the unit will operate in the heat pump
mode. If the room temperature continues to decline with
the heat pump operating, heat pump operation will
terminate and the unit will switch over to electric resistance
heat to warm the room. This heat source logic allows the
heat pump to operate to lower outdoor temperatures,
increasing the savings from heat pump operation, while
providing the ability to use resistance heat only when
necessary. The heat pump and the electric resistance heaters
never operate simultaneously on the Zoneline 3200 Series
Units.
Heat pump defrost - 3200 Series
If the outdoor coil drops below 9°F. (which corresponds to
approximately 25°F. outdoor air temperature), the unit
employs a passive defrost system. A “passive defrost system”
prevents heat pump operation until outdoor temperatures
rise sufficiently to enable economical heat pump operation
to resume. During the defrost mode, the indoor temperature
is maintained by the electric resistance heaters. The defrost
cycle terminates when the outdoor coil temperature rises
above 36°F., at which point the two-stage thermostat will
allow the unit to return to economical heat pump operation.
Heat pump condensate
See page 32 for information on heat pump condensate. The
Zoneline 3200 Series heat pumps may be ordered with a
factory installed Internal Condensate Removal (ICR) system
to minimize the amount of condensate water draining from
the unit during heat pump operation.

Heat Pumps and Energy Savings
• Heat Pump Operation — Zoneline 5200 Series
Heat sources: Heat pump, heat pump and simultaneous electric
resistance heat, or electric resistance heat
The Zoneline 5200 Series heat pumps employ a highly
featured microprocessor control system interfaced with
thermistors to accurately measure indoor air temperature,
outdoor air temperature, indoor coil temperature, and
outdoor coil temperature. This system allows the
microprocessor to precisely and predictably react to
changing conditions in order to provide a very advanced
Packaged Terminal Heat Pump operating system.
The Zoneline 5200 series is designed to help insure a
comfortable room. When “HEAT” is selected, the unit will
determine if the room air is warm enough to satisfy the
thermostat setting. If the temperature at the unit sensor is
below the desired temperature, the electric resistance heater
will be utilized to warm the room to the point where the
thermostat is satisfied. This feature is designed to allow the
temperature of an unoccupied room to be maintained at an
energy saving level without inconveniencing the room
occupant. Once the thermostat has been satisfied, the
resistance heater will turn off and the heat pump will
operate as shown in Zoneline 5200 Series Heat Source Logic
chart when the thermostat calls for heat again. The unit will
operate in this manner even if connected to a Central Desk
Control.

determines the need for defrosting by criteria based on
continuous compressor running time, outdoor air
temperature, outdoor coil temperature, and the rate of
temperature change of the outdoor coil. When defrosting is
required, the unit reverses the flow of refrigerant to direct the
hot gas into the outdoor coil to melt the frost build-up.
Before and after actual reverse cycle defrosting, the unit shuts
off the compressor to allow the refrigerant pressures to
equalize throughout the system. This eliminates the
possibility of a loud reversing noise. During these periods of
pressure equalization, the full resistance heat capacity of the
unit is activated to help insure room comfort conditions
during the defrost cycle. The defrost cycle termination
requires a minimum of 2 minutes and a maximum of 9
minutes or an outdoor coil temperature of 68°F.
Heat pump condensate See page 32 for information on heat

Central Desk Control -
Optional Interface Module (RAKOIM) is
required
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, signalling the air conditioner to turn 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 14.
There are 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. No external
power source is required to operate this system. The unit
provides a 24 volts DC circuit that powers the Central Desk
Control system.
All Zoneline 2200, 3200, and 5200 Series units can have the
Optional Interface Module (RAKOIM) field installed to
provide a CDC interface that permits the unit to be
connected to most of the energy management systems on the
market. The devices connected to the Zoneline units require
no power supply or transformer external to the unit.

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

transom, for instance, where the unit
mounted controls are inaccessible, can
be connected to a wall mounted
thermostat. The unit is connected to the
thermostat by low voltage wiring which
permits the operation of the unit to be
selected and the temperature to be
sensed at the thermostat. Other
installations may use remote thermostat
control for design or performance
