Chassis Features and Benefits
• Permanently Lubricated Fan Motors /
Indoor and Outdoor Air Movers
Designed for low maintenance and optimum value, efficiency, and
performance
Zoneline units have permanently lubricated fan motors. Fan
motors that require oiling on a periodic basis generate an
additional maintenance cost for removing, oiling, and
reinstalling the units in the wall case. The Permanent Split
Capacitor (PSC) motors used in Zonelines are permanently
lubricated and totally closed to prevent dirt and foreign
material from entering the motor and shortening its life.
2200 and 3200 Series units use squirrel cage indoor blower
and propeller type outdoor fan. The Zoneline 2200 Series
Packaged Terminal Air Conditioner (PTAC) and the
Zoneline 3200 Series Packaged Terminal Heat Pump
(PTHP) use two fan motors to operate the indoor blower
and the outdoor fan. A squirrel cage blower on the indoor
side combined with 2 discharge ports provide balanced
temperature air flow and quiet operation. The outdoor fan
is a molded polymer propeller type fan. The outdoor fan
motor does not operate in FAN ONLY or in resistance heat
operation on 2200 series.
5200 Series units employ a cross-flow indoor blower and
propeller outdoor fan. The Zoneline 5200 Series PTHP has
two fan motors. A quiet, efficient, tangential cross-flow
blower is driven by the indoor fan motor. The outdoor fan is
a molded polymer propeller type fan driven by a separate
motor. The outdoor fan motor does not operate in FAN
ONLY.

• Rotary Compressor
Fewer moving parts for quiet, dependable service
GE introduced the use of rotary compressors in their air
conditioners in 1957. Today, rotary compressors are the
quiet and efficient compressor choice for Packaged
Terminal Air Conditioners and Heat Pumps.

• Control Devices
Designed to maximize value and room comfort
All Zonelines have electronic thermostats. Electronic
thermostats utilize a thermistor to sense room temperature.
A thermistor is a resistor that changes value (resistance)
with a change in temperature. The resistance changes
rapidly and predictably with temperature. Interfaced with a
microprocessor in the Zoneline 2200, 3200 and 5200 series
units, the thermistor can sense temperature changes as small
as 0.2°F. in staged heating and less than 1.0°F. in the
heating and cooling modes.

Automatically turns on resistance heaters to help prevent damage
from freezing temperatures

is standard on the Zoneline. The
temperature in unoccupied rooms may fall below freezing
during extremely cold weather. In these circumstances,

air temperature sensor.
• Compressor Restart Protection
Electronically locks-out compressor operation to allow system
pressure equalization
Compressor Restart Protection is standard on all Zoneline
Units, and prevents the compressor from starting before
sufficient time has elapsed for the internal refrigerant
pressures to equalize. This situation could occur if a room
occupant turns the unit back on too quickly after shutting it
off - or if the thermostat is adjusted immediately after the
compressor has shut off. By locking out the compressor until
the pressures have equalized, the thermostat prevents the
compressor overload from tripping. That in turn, alleviates
any anxious moments for the room occupants while they
wait for the overload to reset.

• High Ambient Heat Pump Operation
Protection
Automatically protects the compressor during heat pump
operation.
High Ambient Heat Pump Protection is standard on the
3200 and 5200 Series Zoneline.
If a heat pump is operated in the HEAT mode when
outdoor temperatures are at a point where heat is not
normally required, the compressor may cycle on the
overload protector. An electronic sensor monitors indoor
coil temperature and terminates outdoor fan operation
when high temperatures are reached and resumes when the
indoor coil temperature drops.

• Emergency Heat Switch
The 3200 and 5200 Series Models are equipped with an
emergency heat switch that overrides the heat pump feature
and energizes the electric resistance heaters. With the
emergency override dip switch set, the heat pump function
is locked out and the unit operates as an electric resistance
heat model. Operating the unit in resistance heat results in
higher utility costs.
