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.

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.

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.

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

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.

Safety Instructions Operating Instructions Care and Cleaning Troubleshooting Tips Consumer Support

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.
