INTRODUCTION
How do we know?
Well, for one thing you just bought a Trane
Home Comfort Sensor, the communications inter-
face for the Trane Integrated Comfort System.
This means you’ve opted for energy efficiency,
lower utility bills and doing a little something to
save the planet–all in one bold move.
As you know, this is an instruction manual for
the Home Comfort Sensor.
Even the most intuitive trailblazers need
a road map sometimes, so this manual was
designed to be as self-explanatory as possible.
The Home Comfort Sensor is a computer, but
that’s the last time we’ll mention it. These
instructions are in plain English with only a cou-
ple of unusual words like setpoint and LCD. No
technical talk, no complicated diagrams. All you
have to do to become a Home Comfort Sensor
expert is follow the simple steps in this booklet.
But before we begin, you might want to spend
a few moments looking over the glossary of terms
on the next page. It will make those unusual
words we mentioned earlier more meaningful.
You’re a very bright person.

For one thing, it can take a load off your mind.
Once you’ve entered the setpoints on the Home
Comfort Sensor, it will maintain comfort control
for you. It will adjust your home‘s heating and
cooling when it’s supposed to, and it won’t forget,
as a mere mortal might.
It will remember what you tell it, even during
emergencies. You’ll be happy to know that –
unlike your VCR and other electronic digital clocks
– the Home Comfort Sensor won’t forget its
setpoints during a power failure. You have plenty
of other things to worry about when that happens.
You probably won’t find the instruction manual
by then anyway, so that’s why we’ve included
three button batteries for power backup. Simply
install them and don’t worry about a power failure
knocking out your Home Comfort Sensor thermo-
stat. When the LCD clock flashes, it’s time to
replace your batteries and re-set your clock. But
even when you have to change your batteries, your
Home Comfort Sensor won’t forget its setpoints.
The Home Comfort Sensor spends
practically all of its time connected to AC house
power, but when the word Connect is displayed in
the lower left corner, your thermostat is running
on battery power and needs to be reconnected to
AC power. When the thermostat is running on
batteries, it will automatically go into a battery-
saving mode to extend the life of the batteries.
Don’t be alarmed if you see the word Off dis-
played on the front panel. This simply indicates
that the AC power is off. Press any key to exit the
battery saving mode.
The Home Comfort Sensor will stay in touch
with you and your home comfort system. A little
green light will flash to let you know it’s talking
with the heat pump or air conditioner. That’s
good. The last thing you want is a senseless
sensor.
What The Home Comfort Sensor Can Do For You:

BASIC
PROCEDURES
Start-up begins with four simple steps:
1. Find a comfortable, well-lit spot to
sit down with the Home Comfort Sensor and this
manual. (Relaxing in an easy chair is the most
comfortable way to meet new challenges.)
2. Remove the front of the Home Comfort
Sensor from its mounting bracket. On the back
side you’ll see the batteries on the left edge.
Remove the plastic insulating strip from between
the batteries. The Home Comfort Sensor will then
begin operating after a short delay.
Now you can adjust your setpoint and set the
clock right from the comfort of your easy chair.
3. This sensor has a back lit display. This will
help you see the LCD if the lighting is dim. It is
activated by pressing one of the keys on the key
pad and will be on for approximately 25 seconds.
4. Read on.
Ready, Set…Relax.

BASIC
PROCEDURES:
CLOCK HOW DO I MAKE IT STOP FLASHING?
Answer: Tell the Home Comfort Sensor what
time it is.
TIME, PLEASE?
CLOCK triggers the Set Time mode. It
also hides everything else on the LCD so
you can focus on the job at hand.
Keep pressing CLOCK. Whatever flashes
– digits or words – may be set with the
UP or DOWN ARROW keys.
Settings go in the following order:
hours, minutes, days. But you’ve
probably already figured that out.
The clock is preset to display
standard time. If you prefer a
24-hour clock (military time),
see page 11.
EXIT locks in the correct time and day,
as well as returns normal display to
the LCD.

BASIC
PROCEDURES:
MODE Depends on the season, right?
HEAT/COOL sets the mode, just as the
flip switch did on your old thermostat.
But HEAT/COOL gives you more options.
As you press HEAT/COOL,
the LCD offers
• Cool
•Heat
• Auto – the Home Comfort
Sensor decides which mode,
cooling or heating, is needed
to maintain the setpoint; an
excellent feature for
in- between
seasons when days are warm
and nights are chilly.
•Emergency Heat (Emerg Ht) –
directs the auxiliary heat
source to kick in (if your system
has one). The compressor
won’t run in this mode.
•Off
