on the back of the thermostat (see fig. 1) and switch it to the

ELEC position. This will allow the thermostat to energize the fan

immediately on a call for heat. If you are unsure if the heating/

cooling system requires the thermostat to control the fan,

contact a qualified heating and air conditioning service person.

When the thermostat is configured for Heat Pump, the thermo-

Attach Thermostat Base to Wall

1.Remove the packing material from the thermostat. Gently

pull the cover straight off the base. Forcing or prying on

2.Connect wires beneath terminal screws on base using

appropriate wiring schematic (see figs. 2 through 3).

3.Place base over hole in wall and mark mounting hole

4.Move base out of the way. Drill mounting holes.

5.Fasten base loosely to wall, as shown in fig. 1, using two

mounting screws. Place a level against bottom of base,

adjust until level, and then tighten screws. (Leveling is for

appearance only and will not affect thermostat operation.)

If you are using existing mounting holes, or if holes drilled

are too large and do not allow you to tighten base snugly,

6.Push excess wire into wall and plug hole with a fire-

resistant material (such as fiberglass insulation) to

prevent drafts from affecting thermostat operation.

2 “AA” alkaline batteries are included in the thermostat at the

factory with a battery tag to prevent power drainage. You

must remove the battery tag to engage the batteries.

If “BATT” is displayed, the batteries are low and should be

replaced. For best results, replace all batteries with new

premium brand alkaline batteries such as Duracell® or

Energizer®. To replace batteries, press system button to

OFF, install the batteries along the top of the base (see Fig.

1). The batteries must be installed with the positive (+) end to

Your thermostat is designed to determine the
optimum time to activate the second stage.
Simply raising the temperature in heating or
lowering it in cooling will not always force the
thermostat to bring the second stage on quickly.
There is a time delay from 0-30 minutes depend-
ing on the performance of the first stage of the
system.

Symptom

Forgot Keypad
Lockout Code ( conti nued)

Why won’t my 2nd or
3rd stage come on?

Possible Cause

First stage is keeping up with demand.

Corrective Action

Your thermostat display can be set to display temperature in Fahrenheit or
Celsius. This option can be set in the INSTALLER/CONFIGURATION MENU
of your thermostat. See page 6 step 12.

There is no need to select a time to stop a programming period. Starting a
new programming period will stop the previous program period.

Unless the thermostat appears to be damaged it will follow the program that
is in the memory. The most common reason a thermostat will appear not to
be following the program is a programming error. Verify that the AM or PM
settings are correct for each period. Also verify that the Day of the week is set
correctly. Models with EMR (Energy Management Recovery) start early to
make the temperature they are programmed for by the time specified in the
program. See the CONFIGURATION MENU on page 6 step 3.

Any time you wish to turn your system off, simply press the SYSTEM button
until “OFF” is displayed. This will not affect your thermostat’s programming
in any way. To turn the system back on, press the SYSTEM button to HEAT
or COOL and press RUN. The system will begin operating according to the
current thermostat program. See under OPERATION page 8 & 9.

Because it is soldered to the circuit board it is not possible to repair or
replace.

No. This thermostat has permanent memory, although you will have to reset
your clock.

When the thermostat compressor time delay occurs it will flash the setpoint
for about five minutes. This is intended to help protect the compressor from
short cycling.

You can perform software reset by pressing

simultaneously when SYSTEM mode is OFF. See “Forget Keypad Lockout
Code” under “TROUBLESHOOTING” for details.
