Features and Benefits
Fan-Only Setting – HIGH/LOW
The unit provides the option of selecting either HIGH or LOW speed for
Fan-Cycle Switch – “SmartFan”
Unique “SmartFan” allows unit to operate fan continuously
in cooling operation and fan cycle in heating to provide better guest comfort. Eliminates complaint of cold air draft during heating operation.
Eliminates need of changing
“SmartFan” settings are controlled via the auxiliary control setting push button.
Compressor Random Restart
In the event of a power failure, all compressors attempting to restart immediately when power is restored can result
in a power surge that can cause another power interruption.
The microprocessors in the Zoneline® units have a random restart logic system that prevents all units from starting at the same time.
Rotary Compressor
Smoother operation for quiet, dependable service. GE has used rotary compressors since 1961.
Compressor Restart Delay
Zoneline units are designed to provide a minimum of three minutes of compressor off time to allow refrigerant pressures to equalize before restarting to prevent compressor damage.
Zoneline units are also designed to provide a minimum of three minutes of compressor run time to prevent room occupant disturbance due to
Freeze Sentinel™
Detects low room temperature and turns on heater to help protect against damage caused by freezing room temperature.
Heater turns on at 41°F and warms indoor thermistor temperature to 46°F and shuts off.
Freeze Sentinel may be turned off by dip switch on auxiliary control.
Heat Sentinel
The property owner may choose to activate the Heat Sentinel feature on the Zoneline unit. If the Heat Sentinel is activated and room temperature reaches 85°F while the
unit is in the “STOP” setting, the unit will automatically start in air conditioning operation and will shut off when the room temperature reaches 80°F. This will help dehumidify the air and lower high temperatures so the guest will not be entering an extremely hot room.
Indoor Coil Frost Control
Prevents indoor coil from freezing and causing complaints due to lack of cooling. Frost can form on the indoor coil when the unit is operated in cooling when outdoor temperatures are low. The unit automatically shuts the compressor off until the indoor coil temperature warms to the point where frosting will no longer occur.
Transfer Fan Interface
24 VAC terminals are provided to operate a relay to control a fan mounted in a wall to move conditioned air into another space. The electrical power for the operation of the transfer fan itself is not provided by the Zoneline unit. Transfer fans and their controlling relays are field supplied.
Electronic Temperature Limiting
Seven independent programmable heating temperature limits and seven independent programmable cooling temperature limits.

Energy Management System Interface with
All units have a switch via the auxiliary control setting to allow the indoor fan to continue operating if the unit is connected to an energy management system that shuts off compressor or heater operation. By allowing the indoor fan to run when the heater or compressor is shut off by the energy management system, the guest is less likely to realize the operation of the unit has been altered. This helps reduce peak energy demand loads without disturbing the room occupant.
Reversible Indoor Air Louvers
Allows air to be directed into room at 40º or 50º angle to provide better air distribution.
Angle is changed by removing room front and screws holding louver in place, and rotating louver section.
