PRODUCT FEATURES AND BENEFITS (cont)

EASY ACCESS TO CHASSIS

Access to the chassis simply requires removing four

screws and then sliding the chassis out of the sleeve

for service. Once the power is turned off, connectors

can be separated on hard-wire units, or the power cord

can be disconnected on cord-connected units.

HIDDEN CONTROLS

The factory-wired control box houses all control com-

ponents and is quickly accessible without removing

the chassis from the wall sleeve. Remove two screws

and the hinged door lowers, providing quick access to

all the components and the wiring diagram.

Temperature Limiter

The limiter reduces operating costs by allowing the

owner to control the range of cooling and heating tem-

peratures available to the occupant. It is located under

the control panel, out of the occupant’s sight. Each

setback on the limiter is equivalent to 5° F and the

range of temperature settings available to the owner is

from 60 to 90 F. The limiter is not pre-set at the

factory.

The occupant’s temperature control knob is conve-

niently located on the control panel and is clearly marked

with a range of dial settings.

Outdoor Air Vent Control

The vent knob is located under the front panel. This

knob slides to manually open and close the outdoor

vent.

Fan Cycle Switch

This switch (not available on RC models) allows the

fan to operate in 2 modes:

• Continuous — This setting allows the fan to run con-

tinuously, circulating air even when the temperature

setting has been satisﬁed. This setting, which helps

to keep the room temperature closer to the thermo-

stat setting, is used for maximum comfort.

• Cycle — This setting allows the fan to cycle on and

off with the compressor during heating or cooling.

The fan stops when the temperature setting is reached.

The longer unit off-time makes this option more

energy-efficient with only slightly wider variations

in room temperature.
