Indoor Fan Speed Selections - AUTO/HIGH
Unit may be operated in HIGH HEAT, AUTO HEAT, HIGH COOL or AUTO COOL.
In “AUTO”, the indoor fan will be in low speed for quieter operation if the room temperature is within 1.8°F of the set point, or in high speed if the room temperature is more than 1.8°F away from the set point.
This feature allows the greatest control over the room temperature while reducing the operating sound level.
Fan Only Setting - HIGH/LOW
The unit provides the option of selecting either HIGH or LOW speed for Fan Only operation.
Fan Cycle Switch - “SmartFan”
Unique “SmartFan” allows unit to operate in fan continuous in cooling operation and fan cycle in heating to provide better guest comfort. This eliminates complaint of cold air draft during heating operation.
This feature eliminates need of changing fan cycle switch seasonally.
“SmartFan” settings are controlled by separate fan cycle/ continuous switches for heating and cooling modes.
Automatic 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 microprocessor 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
Zonelines are designed to provide a minimum of three minutes of compressor off time to allow refrigerant pressures to equalize before restarting, to prevent damage to compressor.
Zonelines are also designed to provide a minimum of three minutes of compressor run time to prevent room occupant disturbance due to short cycling air conditioner.
Freeze Sentinel™
Detects low room temperature and turns on heater to help protect against damage by freezing temperature in the room.
Heater automatically turns on at 41°F, warms indoor thermistor temperature to 46°F, and shuts off.
Freeze Sentinel may be turned off by dip switch on auxiliary control.
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. Transfer fans and their controlling relays are field supplied.
Electronic Temperature Limiting
7 independent programmable heating temperature limits and 7 independent programmable cooling temperature limits. Wide selection of limits eliminates need to reset the limits seasonally.

Energy Management System Interface With Load Shedding Option
All units have a switch on the auxiliary control panel 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 to reduce peak energy demand loads without disturbing the room occupant.
Reversible Indoor Air Louvers
Allows air to be directed into room at 40 or 50 degree angles to provide better air distribution.
Angle is changed by removing room front and screws holding louver in place and rotating louver section 180°.
