Welcome . . . to the family of
American Standard comfort
products. We sincerely believe
that your new American Standard
Central Air Conditioning System
will provide you with many years
of reliable service.
With Two Stage Heating
operation, you will realize
operating economics with an
energy efficient system, while
enjoying gentle, filtered,
conditioned air flowing from your
new American Standard system.
This booklet has been prepared
with the owner in mind. We hope it
will help you understand the
system, and assist you in obtaining
its most efficient operation, and
serve as a guide should you have
questions or problems concerning
the system.
How To Operate Your Heating/Cooling Manual Thermostat
A. Temperature Selector
B. Temperature Indicator
C. System Switch
D. Fan Switch
Setting the Temperature (A)
The lever on top of the
thermostat is for selecting the
desired indoor temperature for
heating and/or cooling.
For cooling, set the cooling
temperature selector at the
desired indoor temperature and
the system switch to COOL.
For heating, set the heating
temperature selector at the desired
indoor temperature and the
system switch to HEAT.
This thermostat is designed to
optimize your Two Stage Heat
Furnace for maximum efficiency
and comfort. The thermostat
signals the furnace system
control for heating requirements
in low or high heat.
Setting the Fan Switch
continue to run when there is no
heating or cooling required. This
provides constant air filtering and
more even air distribution to all
conditioned spaces. In some
cases, particularly with multi-level
homes, comfort may be enhanced
by continuous circulation of indoor
air.
To turn the system OFF, position
the switches as follows:
SYSTEM — OFF; FAN — AUTO:
CAUTION: In cooling mode, rapid
changing of the thermostat
temperature setting in such a
manner that turns the compressor
OFF and ON rapidly may cause
the compressor motor protector
to open and turn OFF the
compressor for a short time.
The protector is an automatic reset
type and the compressor
will restart after a few minutes.
“Jiggling” the thermostat is not
recommended. Anytime the
system is turned OFF, allow
approximately 5 to 10 minutes for
system pressures to equalize
before restarting.
The Fan Switch may be set at:
AUTO or ON.
When the Fan Switch is set to
AUTO, the indoor fan will cycle
“on” with the call for heating or
cooling and “off” when the
thermostat is satisfied. This “on”
and “off” cycle is controlled by
the thermostat as it operates the
system to maintain the selected
indoor temperature. This mode of
operation will provide the lowest
operating cost and better humidity
control in cooling operation.
When the “FAN” switch is in the
“ON” position the fan will run
continuously. With the “FAN” in
the “ON” position your cooling
and heating system will still
operate as the conditioned space
temperature requires, but the
indoor fan will not cycle off. It will

may seem cool but it is also
moisture-laden. This increases
the work your system must do
the next day.
6. Don’t block supply and
return registers with furniture
or drapes. — Don’t let shrubs,
vines, or fences block air
intake and/or discharge on
condenser unit outside. Don’t
put a lamp, TV or radio too
near your thermostat.
7. Don’t try to operate unit if
there is any indication of a
malfunction. — Turn the
system “OFF” at the
thermostat immediately, and
call your serviceman.
Indications of malfunction
include: no cooling, short
cycling of compressor or
motors, and unusual system
noises.
1. Do use filters — Clean or
replace filters monthly. (Note:
turn off all electrical power to
unit and turn thermostat to OFF
position before you start).
Follow a Few Basic Rules:
1. Don’t be a “thermostat
jiggler.” — Set the thermostat
at the desired temperature and
forget it. Frequent changing
upsets temperature and
humidity control and may
increase operating cost.
2. Don’t set the thermostat too
low for cooling or too high for
heating. — The greater the
difference between the
outdoor and indoor
temperature — the greater the
operating cost.
3. Don’t turn the system off just
because you’ll be away for a
day or two. — It takes quite a
while to restore comfort — but
costs relatively little to maintain.
4. Don’t be concerned if your
air conditioning unit operates
after sundown. — Heat stored
in the roof and walls is still
there. On exceptionally hot
days, expect your unit to work
more.
5. Don’t open windows after
dark. — The summer night air

KEEP FILTERS CLEAN —
This is an important
responsibility. A dirty, clogged
filter reduces the efficiency of
your system, causes erratic
performance of controls —
can result in damage to the
motor, heating element, or to
the compressor. On new
homes check filters every
week for four weeks to begin
with.
2. Do keep windows and doors
closed — (and pull drapes or
shades on windows exposed
to the sun). The less heat and
moisture there is to remove —
the lower your operating cost
for cooling; in addition,
airborne dust and pollen are
minimized.
3. Do “heat and moisture” work
— in the morning as much as
possible. Then your cooling
system can easily offset the
effects of washing, drying,
mopping, etc. before afternoon
heat arrives.
4. Do turn on bathroom exhaust
fan — (or open window slightly)
during showers. Use plastic
shower curtains instead of
moisture-holding fabric
curtains.
5. Do keep attic ventilators
open. — Attic space can
become an oven unless there
is good ventilation.
Consider this:
During cooling season, when
possible, avoid adding heat such
as clothes dryer and kitchen
range during peak temperature
periods in the afternoon.
In winter, excessive use of
fireplaces and open chimney
dampers will draw warm air out of
the conditioned space and add to
operating cost of the system.
A regular program of service/
maintenance can extend the life
of your heating and cooling
system and ensure maximum
efficiency. See your American
Standard service dealer for
maintenance details.
