Features and Benefits

Standard Physical Dimensions
GE has maintained the same dimension since 1961- 42" wide
x 16" high x 13 3/4" deep.
Replacement of older units 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 non-ICR units -
10 CFM on units with ICR.
Industry specification is 19 CFM of air infiltration.

Unit Controls

2500 and 3500 series - rotary knobs for temperature and
operation selection
5500 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 the outstanding features on
the units.
Thermistors are used to sense
small changes in temperature to
give excellent room control and
to 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
5500 series Zoneline does not utilize the resistance heater
when the outdoor temperature is above 45°F during normal
operation. The resistance heat is used in the Quick Heat
Recovery feature.
Automatic Emergency Heat
Heat Pump Defrost Systems
See pages 19 and 20 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.
Shuts the outdoor fan 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 5500 series has a dip switch that activates each of the
various components of the unit to operate briefly. This
enables the service technician to determine if individual
components are functioning properly.
Service Indicator
On the 5500 series, the microprocessor detects a compressor
malfunction, the digital temperature display will blink. If the
malfunction occurs during cooling operation, the indoor
fan will operate to circulate room air. If in the heating
mode, the unit will automatically switch to resistance heat so
the room occupant will not be uncomfortable. The blinking
display is an alert that the unit is operating in the more
expensive resistance heat mode.
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.
