How do we know?

Well, for one thing you just bought a Trane

Master Scheduler, the communications interface

for the Trane Integrated Zone

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.

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.

INTRODUCTION You’re a very bright person.

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.

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.

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.

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

OVERVIEW

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.)

You can start by pushing the right buttons.

Adjusts settings in various modes;

pressed once, they reveal current set-

points; pressed more than once they

temporarily adjust temperature settings.

Permits you to override scheduled set-

points in order to schedule temporary

temperature adjustments.

Initiates setback scheduling.

Programs setback time and

temperature setpoints.

GETTING

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

What The Master Scheduler Can Do For You:

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

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.

*Of course, the hours, minutes and day indicators will flash when we

are setting the clock (even when the batteries are OK).

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.

PROCEDURES

eady, Set…Relax.

HOW DO I MAKE IT STOP FLASHING?

Answer: Tell the Master Scheduler

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.

Your First Question Is Probably Going To Be:

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.

Setback scheduling. What’s that, you say?

Setback means different temperature set-points

for different times and days. It’s why you bought

the Master Scheduler, right? And it’s a feature

you’ll love, especially when you begin to notice

the savings on your utility bills.

• Press PERIOD to start scheduling.

(The word Schedule will light up.)

The six setback periods will be

displayed in sequence when you

continue to press PERIOD. An arrow

period.

Naturally, the Master Scheduler will accept whatever

time you enter into each of the setback periods.

• Press ZONE to select the zone you wish to

program.

• Press TIME/TEMP until the hours flash,

then press either ARROW to reach or

change the hour you want to initiate

this setpoint. Press TIME/TEMP again to

adjust the minutes in 10-minute

intervals.The bars at the bottom of the

display will graphically show the

relationship between this period and

adjacent periods.

Note: There is no need to program a “stop” time.

(This is determined by the “start” time of the next

time period.)

the ARROWS. Follow the same

procedure for your Cool setpoint.

Note: The Cooling setpoint will always be at

least four degrees higher than the Heating

setpoint. If one setpoint infringes on the required

four-degree separation, the Master Scheduler will

automatically adjust the other to maintain the

difference.

Maybe you’re mostly happy with your new

schedule, but right now you wish the temperature

were different. There’s a way to temporarily override

your scheduled setpoints until the next setback

period rolls around or until you change your mind

again, whichever comes first.

• Press either ARROW, and you’ll see

Say you’re going on vacation. Maybe you have

picky houseguests. Or you’re keeping unusual

hours. For whatever reason, you want the Master

Scheduler to maintain a constant temperature in a

zone, but you don’t want to reschedule all the

setback temperatures you entered earlier. Here’s

how to HOLD that constant temperature.

• Press either ARROW to display and

change the setpoint to a new

temperature. Then press HOLD SET

POINT to lock in your new selection.

That’s where it will stay until you tell it

otherwise.

• Press EXIT to return the LCD to its

normal display. HOLD should now

be blinking.

• To cancel HOLD and return to your

original schedule, press EXIT or

The “HOLD SET POINT” command will

stay in effect until you cancel it.
