ControlsTerminal 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.)

Safety Instructions
Controlsterminal connections.
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.
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.

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.
Consumer Support
NOTE: If GE thermostat RAK148D1, RAK148P1 or RAK164D1, RAK164P1 is used with the unit, the room sensor kit is not needed for temperature limiting since this feature is incorporated in the thermostats.

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.

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

Care and Cleaning
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.
Troubleshooting Tips

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

Ventilation Control
The ventilation control lever is located on the left side of the Zoneline unit, behind the front case
Care and Cleaning
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.

Energy Tip: Keep the vent control in the CLOSE position. The room air will be filtered and circulated.
Troubleshooting Tips
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.
About Heat Pumps (on some models)
Heat pumps can reduce operating costs by exchanging heat from the outside aireven when the outside temperature is below freezing and releasing that heat indoors.
Consumer Support
To get the best economic benefit from your heat pump, dont change the room thermostat setting very often. Raising the heat setting 23 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.
