The dip switch controls are located behind the
front case panel, through an opening on the
front of the unit.
To access the dip switches, remove the front
case panel by removing the filter, taking out the
four front screws, the upper two screws from the
top of the panel and the shipping screws on each
side, if present. (Discard the two side shipping
screws, if present).
The factory settings will be in the DOWN position.
NOTE: The owner is responsible for setting
the appropriate dip switches and connecting
terminals.

Controls–dip switches.
Freeze Sentinel (Requires room air sensor kit–RAVRMS)
When this switch is enabled (UP) , it turns OFF the
freeze sentinel protection feature. With the
switch disabled (DOWN) , the freeze sentinel is
activated which automatically provides heat
without user interface. This helps to prevent
plumbing damage by turning the heater and
fans ON at 41° F and OFF at 46° F.
Constant ON Fan
When this switch is enabled (UP) , it allows the
fans to run continuously, at high speed, even if
the unit is in the STOP position.
Occupancy Sensor
When this switch is enabled (UP) , it allows the
unit to utilize an infrared motion sensor and a
door switch for occupancy detection. This feature
allows an energy management system to be
installed and operated in conjunction with
the unit.

Duct
The duct select function allows the indoor
fan to be operated at two variable fan speeds,
depending on the duct length. When this switch
is enabled (UP) , the unit automatically selects
either high or middle fan speed for longer
ductwork applications. When set in the down
position, the unit is automatically operated in
either the middle or low fan speed for shorter
ductwork applications.

Temperature Limiting (Requires room air sensor kit–RAVRMS)
Temperature limiting can reduce energy costs
by limiting the lowest temperature that can be
set for cooling and the highest temperature that
can be set for heating. Temperature limiting is
controlled by switches 1–6 on the top block
of auxiliary controls. The first three switches are
used to select the cooling limits. The next three
switches are used to control the heating limits.

Controls—terminal connections.
Controls–Terminal Connections
The terminal connections are located behind the
front case panel through an opening on the
front of the unit.
To access the terminal connections, remove the
front panel by removing the filter, taking out the
four front screws, the upper two screws from the
top of the panel and the shipping screws on each
side, if present. (Discard the two side shipping
screws, if present).
Insert the building hook-up wires into the
bottom of the terminals and tighten screws
securely to make the desired connections.
Route the wires from the terminal connections
through the unit wire guides and out through
the case wire guide.
NOTE: The owner is responsible for setting
the appropriate dip switches and connecting
terminals.
CAUTION:
Improper CDC wiring may damage the Zoneline
electronics or cause erratic Zoneline operation.
No common busing is permitted. A separate wire
pair must be run from each separate controlling
switch to each individual Zoneline.
Room Air Sensor (Requires room air sensor kit – RAVRMS)
When connected, the room air sensor will allow
utilization of the temperature limiting and freeze
sentinel features.
NOTE: If GE thermostat RAK147P2 or RAK163P2
is used with the unit, the room sensor kit is not
needed, since temperature limiting and freeze
sentinel features are incorporated in the
thermostats.

IMPORTANT:
The Zoneline thermostat connections
provide 24V AC only.
If using a digital/electronic wall thermostat,
you must set it to the 24V AC setting. See the
Installation Instructions for the wall thermostat.
CAUTION:
Damage to a wall thermostat or to the
Zoneline electronics can result from improper
connections. Exercise extra attention when
connecting blue and black wires. No line
voltage connections should be made to any
circuit in the thermostat. Isolate all wires in
building from line voltage. 7

Door Sensor (Obtained locally)
The Occupancy Sensor dip switch must be in the
up position to use this feature.
When connected, the door sensor will detect
when the door in the room is opened or closed.
This feature must be used in conjunction with
the motion sensor.
The door and motion sensors work together
to automatically cycle the unit between normal
and energy management operations.
Central Desk Control
When connected, the unit lock-out is released
and it can be turned ON or OFF with a switch
located at the Central Desk Control. A separate
wire pair must be run from each separate
controlling switch to each individual Zoneline.
Motion Sensor (Obtained locally)
The Occupancy Sensor dip switch must be in
the up position to use this feature.
When connected, the wall mounted motion
sensor will detect motion in the room and
automatically cycle the unit between normal
operation and energy management operation.

Other features of your Zoneline.
About Heat Pumps (on some models)
Heat pumps can reduce operating costs by
exchanging heat from the outside air—even
when the outside temperature is below
freezing— and releasing that heat indoors.
To get the best economic benefit from your heat
pump, don’t change the room thermostat setting
very often. Raising the heat setting 2–3 degrees
will cause the Zoneline to use its electric heating
elements in order to reach the new temperature
setting quickly.
There is a three minute minimum compressor
run time at any setting to prevent short cycling.
The indoor fan motor starts before the
compressor and stops after the compressor
cycles off.
The electric heating elements use much
more electricity than heat pumps and cost
more to operate.
Ventilation Control
The ventilation control lever is located on the
left side of the Zoneline unit, behind the front
case panel.
To access the ventilation control lever, remove
the front panel by removing the filter, taking out
the four front screws, the upper two screws from
the top of the panel and the shipping screws on
each side, if present. (Discard the two side
shipping screws, if present).
When the lever is in the CLOSE position, only the
air inside the room is circulated and filtered.
When the lever is in the OPEN position, some
outdoor air will be drawn into the room. This
will reduce the heating or cooling efficiency.
To close the vent, push the vent lever handle
down, pull it forward and lock it up in place.
To open the vent, push the vent lever handle down,
push it back and lock it up in place.
Energy Tip: Keep the vent control in the
CLOSE position. The room air will be filtered
and circulated.

Indoor/Outdoor Coils
The exhaust coils on the Zoneline should be
checked regularly. If they are clogged with dirt or
soot, they may be professionally steam cleaned by
your GE service center. You will need to remove
the unit from the case to inspect the coils
because the dirt build-up occurs on the
exhaust side.

Care and cleaning. GEAppliances.com
Base Pan
In some installations, dirt or other debris may be
blown into the unit from the outside and settle in
the base pan (the bottom of the unit).
In some areas of the United States, a “gel-like”
substance may be present in the base pan.
Check it periodically and clean, if necessary.
Turn the Zoneline off and disconnect the power supply before cleaning.
Outdoor coils
To maintain optimum performance, change the filter at least every 30 days.
Air Filters
The most important thing you can do to
maintain the Zoneline is to change the filter at
least every 30 days. Dirty filters reduce cooling,
heating and air flow.
Changing the filter will: Decrease cost of operation,
save energy, prevent clogged heat exchanger
coils and reduce the risk of premature
component failure.
CAUTION: Do not operate the
Zoneline without the filter in place. If a filter
becomes torn or damaged, it should be replaced
immediately.
Operating without the filter in place or with a
damaged filter will allow dirt and dust to reach
the indoor coil and reduce the cooling, heating,
airflow and efficiency of the unit.
Replacement filters should be purchased from
your local retailer where air conditioner and
furnace accessories are sold.
Filter size required is 20″x 20″x 1″.
Have the coils cleaned regularly.
