Controls–dip switches.

GEAppliances.com

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.

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.

Remote Thermostat

The unit will be controlled by a remote thermostat.

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.

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.

The door and motion sensors work together to automatically cycle the unit between normal operation and energy management operation.

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

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

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.
