INTRODUCTION You’re a very bright person.
How do we know?
Well, for one thing you just bought a T rane
Master Scheduler , the communications interface
for the T rane Integrated Zone
means you’ve opted for energy efficiency, lower
utility bills and doing a little something to save the
planet–all in one bold move.
You have, at the same time, provided yourself
with many options for controlling, scheduling and
programming your zoned air conditioning system.
As you know, this is an instruction manual for
the Master Scheduler .
Even the most intuitive trailblazers need a road
map sometimes, so this manual was designed to be
as self-explanatory as possible.
The Master Scheduler is a computer, but that’s the
last time we’ll mention it. These instructions are in
plain English with only a couple of unusual words
like setpoint and setback. No technical talk, no
complicated diagrams. All you have to do to become
a Master Scheduler 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.

TERMS
OF
Setpoint – The desired temperature setting. (heating or cooling).
Setback – Energy conserving setpoints for certain periods of the day.
LCD – Liquid crystal display
Default Settings – Factory settings for various periods. (easily changed)
Period – Portion of the day when different setpoints may be desired.
Examples:
Wake
Away
Return
Dead Band – The difference in degrees between the cooling and heating
setpoints (min. 4°F). For the typical setpoints of 78° cooling
and 72° heating the dead band is (78 – 72) or 6°F.
Home Automation – Computer control and/or monitoring of the air conditioning system.

OVERVIEW
Before getting into the nuts and bolts of how to
work with your Master Scheduler , let us take a brief
look at some of the rules it can play:
1. Your installer, (of a zoned system) may have
chosen to use an analog sensor , (thermister)
to control one or more of the zones. He would
then utilize the Master Scheduler as an
interface between the analog sensor
and the system controller , which is
designed to communicate with a digital
thermostat. He could also use the Master
Scheduler as one of the zone thermostats, if
desired. (in addition to its interface role.)
2. When programming setback times and
temperatures, (which we will soon be doing,)
the Master Scheduler can be used to copy
this data from any period to any other period,
in the same zone, other zones, or all zones (a
real time saver).
3. On a zoned system, the Master Scheduler
can be used to override any or all zone
thermostats. (It takes local control away from
the thermostat and substitutes your input to
the Master Scheduler .)

GETTING
STARTED
How T o Bring The Master Scheduler , T o Life.
You can start by pushing the right buttons.
Adjusts settings in various modes;
pressed once, they reveal current setpoints; pressed more than once they
temporarily adjust temperature settings.
Permits you to override scheduled setpoints in order to schedule temporary
temperature adjustments.
Initiates setback scheduling.
Programs setback time and
temperature setpoints.
Copies information to other
periods/zones.
Day/Clock
Selects operational modes: cool, heat,
auto, emergency heat, & off.
T oggles between automatic or
continuous fan operation.
Displays outside temperature.
Initiates setting the clock
Returns normal display to the Liquid
Crystal Display (LCD).
Selects zone number .
Note: The flashing green light in the lower
right corner indicates your sensor is
communicating with the system.

What The Master Scheduler Can Do For You:
For one thing, it can take a load off your mind.
Once you’ve set a schedule on the Master
Scheduler , it will maintain comfort control for
you. Energy efficiency and lower utility bills are
now the Master Scheduler’ s job, not yours. The
thermostat will adjust 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 Master Scheduler 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 factory
installed three button batteries for power backup.
Simply activate them and don’t worry about a
power failure knocking out your Master Scheduler
thermostat.
When the LCD clock flashes, it’ s time to
replace your batteries.* But even when you have to
change your batteries, your Master Scheduler
won’t forget it’ s schedule.
The Master Scheduler will stay in touch with
you and your Integrated Zone
TM
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 .
5
*Of course, the hours, minutes and day indicators will flash when we
are setting the clock (even when the batteries are OK).
BASIC
PROCEDURES
R
eady, Set…Relax.
Scheduling begins with three simple steps:
1. Remove the front of the Master Scheduler
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.
2. Replace the Master Scheduler to its
mounting bracket.
3. Read on.

Your First Question Is Probably Going T o Be:
HOW DO I MAKE IT STOP FLASHING?
Answer: T ell the Master Scheduler
what time it is.
TIME, PLEASE?
Day/Clock
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 21.
EXIT locks in the correct time and day,
as well as returns normal display to the
LCD.

Change Can Do A Body Good.
Maybe you’re mostly happy with your new

your scheduled setpoints until the next setback
period rolls around or until you change your mind
again, whichever comes first.

Say you’re going on vacation. Maybe you have

setback temperatures you entered earlier. Here’s
how to HOLD that constant temperature.
