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
Provides smoother operation for quiet, dependable
service. GE Appliances 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 short-cycling of
the air conditioner.
FREEZE SENTINEL
• Detects low room temperature and turns on heater to
help protect against damage caused by freezing room
temperatures.
• The electric heater turns on at 41°F and warms the
room up to 46°F and shuts off.
• Freeze Sentinel may be turned off via the 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 (even
when the unit is in the “OFF” mode), the unit will
automatically start the 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 (and keeps the
indoor fan running) until the indoor coil temperature
warms to the point where frosting will no longer occur.
TRANSFER FAN INTERFACE
A 24 VAC connector is available (RAKCDC) 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,
power and wiring are field supplied.
ELECTRONIC TEMPERATURE LIMITING
Eight independent programmable heating temperature
limits and eight independent programmable cooling
temperature limits
TEMPERATURE DISPLAY
The GE Zoneline AZ45 and AZ65 temperature display can
be adjusted to display the temperature settings in either
Fahrenheit, or Celsius. The unit is preset from the factory
to read in Fahrenheit, but can be changed to display Celsius
via the auxiliary control setting.

CENTRAL DESK CONTROL CAPABILITY
See page 16.
REVERSIBLE INDOOR AIR LOUVERS
• Allows air to be directed into room at 45
O
or 65
O
angle
(from horizontal) to provide better air distribution.
• Angle is changed by removing room front and screws
holding louver in place on the chassis, and rotating the
louver section 180° and reinstalling.
UP-FRONT AIR FILTERS
Two interchangeable up-front filters, easy to remove and
reinstall, may be cleaned without opening or removing
the room front. Clean filters
by brushing, vacuuming or
back-flushing under faucet
or shower head.

Limits can be adjusted via the auxiliary control settings. To help you with energy
conservation, GE Zoneline units are shipped with truncated temperature limiting
preset to 66° minimum cooling and 78° maximum heating.
