Don’t Worry—Programming Is Easy!

Start Up

This may seem to be a highly comprehensive and lengthy presenta-

tion of our product's features—don’t be intimidated.

We have a lot to say because our product does have a lot of fea-

tures. And we want to make sure you have complete information. You

may find you'll want to use only a simple program…or all the features

we have to offer.

Just follow this manual one step at a time and you should quickly

begin to feel comfortable with your new thermostat.

Besides, we’ve installed preset programs at 78° for air conditioning

and 68° for heating. These programs are up and running immedi-

ately at installation. In case you don’t have time to enter your own

programs right away.

Keyboard Quick Reference

You can generate significant savings with a programmable thermo-

stat. The idea is to reduce usage when you don’t need it—when

you’re not home or at night while everyone’s asleep. For example,

during the heating season you can program lower temperatures dur-

ing the day while you’re at work. Then program a comfortable tem-

perature just before you get home, so you walk into a warm house.

Studies conducted by the Department of Energy estimate that setting

your thermostat back 10° for two-8 hour periods on winter days can

reduce your fuel bill as much as 30%. During the summer, setting

your thermostat up 5° for two periods can reduce your fuel bill as

much as 25%.

And the digital display on your thermostat gives you precise tempera-

ture control for convenience as well as maximum savings and

comfort.

The thermostat is truly 7 day programmable and can hold separate

programs for winter and summer. It is capable of holding 4 separate

heat and 4 separate programs for cool, each day.

You can program Monday to Friday, Saturday and Sunday to have

the same 4 programs as shown in the table or each day can have a

different set of 4 programs. (4 for winter and 4 for summer).

Suggested winter and summer weekday and weekend programs are

shown below.

Keyboard Lock Feature

Your thermostat is provided with an optional electronic keyboard lock.

You may use this feature to prevent tampering with the programs.

The keyboard can be made active by using the key provided with

your thermostat.

If you elect to use this feature, remove the cover from the thermostat

and look for the switch shown below on the printed circuit board near

the key hole. Be careful not to disconnect any wires. Then slide the

keyboard switch to “lock” mode.

Once the switch is moved to “lock” mode, no entry is possible by the

thermostat keys. Even the manual override is not possible. To acti-

vate the keyboard (open lock) for changing programs or setting new

time, insert the key in the key hole. After programming is completed,

remove the key to lock the keyboard again.

If the keyboard selector switch is in “unlock” mode, there is no need

to use key. Programs can be changed any time without using the key.

Reset

When you first install the three AA size batteries, as directed in the Installation Instructions, the thermostat automatically sets the day and time to

Monday, 12:00 AM, shows the current room temperature and is programmed for 68° in heat mode and 78° in cool mode for all 7 days.

Press the reset button to reset and start the clock. Use a thin probe such as a

straightened paper clip to gently push the reset button through the hole in the front

panel. (See Figure 3.) The LCD display should read 12:00 AM, indicate the day of

week as Monday (MO), the current room temperature of your house. If it shows ran-

dom numbers or partial digits, press the reset button once again.

■Initial read-out after pressing reset button.

■Current room temperature is 72°F.

■Day of week is Monday (MO).

■Time is 12:00 AM.

Before Programming

■To program for winter, the function switch (OFF-A/C-HEAT) must

be in the HEAT mode.

■Similarly, to program for summer, the function switch must be in

COOL position.

■You cannot program or view programs in OFF position.

■Whenever the compressor is in 4 minute restart safety delay,

“DELAY” will appear on the display. Compressor will turn on

automatically when this 4 minute delay period is over. This feature

is designed to protect your compressor from restarting too quickly

which could damage the compressor.

■Replace batteries as soon as low battery indicator appears on the

display.

CAUTION: When the batteries are completely dead, the display

will fade out and the thermostat will not switch

“ON” your system.
