Setting the temperature
Place the system switch on COOL, and
the fan switch on AUTO. Then set the
temperature by using the indicator on
the thermostat* control.
Now your system will cool your house
whenever the indoor temperature climbs
above the thermostat setting. It will shut
off when the desired room temperature
is reached.
In winter, it works the same way. When
the system switch is on HEAT, the
system will operate whenever the room
temperature falls below the temperature
setting. Once the desired temperature
is reached, the system will shut off.
Save energy with an electronic
programmable thermostat.*
Program the thermostat for the temp-
eratures that meet your comfort level.
The American Standard electronic
programmable thermostat has up to
four setup or setback periods each day,
plus weekend and vacation programs.
How to operate your system for peak performance
Let the thermostat do its job.
Your system will perform most efficiently
when you let the thermostat control it.
Turning the system on and off manually
is usually much less efficient. So let the
thermostat do its job.
We recommend keeping the tempera-
ture setting at 78°F for cooling, 68°F for
heating. However, you can select
the temperature that meets your
comfort level.
The point is, once you’ve set the
thermostat, keep subsequent adjust-
ments to a minimum.
When you’re going to be away from
home for a few days, or when outdoor
temperatures are moderate, don’t let
the air conditioner run unnecessarily.
Lower the thermostat to 55°F in the
winter. And raise it to 85°F in summer.
Then when you return, or when
temperature conditions dictate, you
can reset the system and it will resume
making your home comfortable again.
Never stop the system by
shutting off the main power.
If the main power is ever disconnected
for more than three hours, turn off the
thermostat. Then wait for at least three
more hours after the power has been
restored before turning the thermostat
back on. Failure to follow this procedure
could result in damage to your system.
How to help reduce
summer humidity.
In summer, your air conditioner does
more than cool the air — it helps remove
the excess moisture, that can make the
inside of your home feel muggy. When
removing this moisture your system
must work harder than when simply
cooling the air.
That’s why kitchens, bathrooms and
utility rooms should have vents and
exhaust fans. These devices help
prevent accumulation of moisture
throughout the rest of the house so
your air conditioner works less to keep
you comfortable.

read the accompanying thermostat manual
for complete operating instructions.
If heating system is not operational during the cold
weather months, provisions must be taken to
prevent freeze-up of all water pipes and water
receptacles. This is very important during times
of vacancy.
