Features and Benefits
Standard Physical Dimensions
GE has maintained the same dimensions since 1961 — 42" wide x 16" high x
Replacement of older units is made easy.
Weather-Protected Electrical Components
Vital electrical components are protected from the weather by locating them on the indoor side of the weather barrier.
Weather-Resistant “Superseal”
Properly installed unit in undistorted case keeps air leakage to a minimum.
7 CFM air infiltration with 25 MPH wind on
Industry specification is 19 CFM of air infiltration.
Heater Sizes to Meet Room Requirements
All units are equipped with a universal heater — the resistance heat output is determined by power connection kit.
Unit Controls
2900 and 3900 Series — touch pad controls for temperature and operation selection.
5800 Series — touch pad controls with digital readout of temperature set point.
Highly Featured Microprocessor Controls
Microprocessor controls are programmed to interface with the temperature sensors to maximize comfort conditions for the room occupant and provide outstanding features.
Thermistors are used to sense small changes in temperature to give excellent room control and allow the microprocessor to monitor and react to changing conditions.
Electric Resistance Heat Lock-Out
To maximize the savings of the heat pump operation, the Zoneline heat pumps do not utilize the resistance heater when the outdoor temperature is above 46°F during normal operation. The resistance heat is used in the Quick Heat Recovery feature.
Automatic Emergency Heat
Automatically uses electric resistance heat if the heat pump output is not sufficient to maintain selected room temperature.

Reverse Cycle Heat Pump Defrost System
Standard on all Zoneline 3900 and 5800 Series heat pumps.
Enables heat pump to operate at lower temperatures when other systems switch to more expensive electric resistance heat.
See pages 18 and 19 for discussion of heat pump operation and defrost systems.
High Temperature Heat Pump Operation Protection
Automatically protects the compressor if heat pump is operated with high outdoor temperatures.
Power to the outdoor fan is turned off if the indoor coil gets too hot during heat pump operation to prevent damage to the compressor.
Quick Heat Recovery – Heat Pump Units
When the unit operation is changed from STOP or COOL to HEAT, the electric resistance heaters are used to warm the room to the thermostat set point. This provides faster room temperature increase for greater guest comfort.
Unit Diagnostics
The 5800 Series has a dip switch that activates each of the various components of the unit to operate briefly. This enables the technician to determine if individual components are functioning properly.
Service Indicator
On the 5800 Series, if the microprocessor detects a compressor malfunction, the digital temperature display will blink. If the malfunction occurs during cooling operation, the indoor fan will continue to operate. If the compressor malfunctions in heating mode, the unit will automatically switch to resistance heat to maintain room temperature set point. GE Service should be called to check the Zoneline.
Fan Motors – Permanently Lubricated
All units have two fan motors for quiet operation and maximum operating efficiency.
Motors are permanently lubricated to reduce maintenance and totally enclosed to keep dirt and water out of the motor windings.
2-Speed Outdoor Fan
The unit automatically selects the most efficient speed for the outdoor fan. The operating sound level is lower when the outdoor fan can operate in low speed yet there are situations where it must operate in high speed. The unit changes the fan speed automatically.
Indoor Fan Speed Selections – HIGH/LOW
Unit may be operated in HIGH HEAT or LOW HEAT or HIGH COOL or LOW COOL.
