C terminal
The C (common wire) terminal is optional
when thermostat is powered by batteries,
W(O/B) terminal
If thermostat is configured for a heat pump
in the Installer Setup, configure changeover

Wire specifications
Use 18- to 22-gauge thermostat wire.
Shielded cable is not required.
Wiring
1 Loosen screw terminals, insert
wires into terminal block, then
re-tighten screws.
2 Push excess wire back into the
wall opening. Keep wires in shaded
area as shown at left.
Plug the wall opening with non-

to "C" terminal
L E A_x G ©E_ C Y R R_,
Install batteries in back of thermostat
(optional if AC powered).
AC Power
The thermostat can be powered by 24
VACpower, or by batteries.
To wire the thermostat [i)rAC power,
connect the common side of the cool-
ing transformer to the "C" terminal as
shown at left.
Important: Remove R/Rc jumper for
2-transformer systems only: (See wiring
diagram on page 5.)
Battery Power
The thermostat can be powered by
batteries alone or, if used with AC
power, can provide backup power.
During power interruptions the
batteries will save time/day settings
and power the display:
After installation, batteries can be
changed without removing the the>
mostat from the wall (see page 15).
To Mount Thermostat
Align the 4 tabs on the wallplate with
corresponding slots on the back of the
thermostat, then push gently until the
thermostat snaps in place.

InstallationGuide
I
Auto
Auto Changeover is a feature used in
climates where both air conditioning and
heating are used on the same day:When the
system is set to Auto, the thermostat
automatically selects heating or cooling
depending on the indoor temperature.
Heat and cool settings must lye at least 3
degrees apart.The thermostat w_ automatically
adjust settings to maintain this 3-degree
separation (called "deadband").
The 3-degree separation between heating
and cooling set temperatures is fixed, and
cannot lye changed.
Adaptive ]intelligent Recove W eliminates guesswork when setting your schedule, lit
allows the thermostat to "learn" how long your furnace and air conditioner take to
reach the temperature you want.
Just set your program schedule to the time you want the house to reach your
desired temperature.The thermostat then turns on the heatfl_g or coolfl_g at just the
right time to reach your scheduled temperature at your scheduled thne.
For example: Set the Wake tline to 6 am, and the temperature to 70°.The heat will
come on beff)re 6 am, so the temperature is 70 ° by the time you wake at 6.
This feature helps prevent damage to the
COlnpressor in your air conditioning or heat
pump system.
Damage can occur if the compressor is re-
started too soon after shutdown.This feature
forces the compressor to wait for a few
minutes betk)re restarting.
During the wait time, the message Cool On
Message flashes untilsafe or Heat On (heat pumps onl)) will flash on
restart time has elapsed the display:When the safe wait time has
elapsed, the message stops flashing and the
compressor turns on.

[f you have di[Yiculty with your thermostat, please try the suggestions below. Most
problems can be corrected quickly and easily:
Display is blank * Check circuit breaker and reset if necessary.
. Make sure power switch at heating & cooling system is on.
• Make sure furnace door is closed securely.
• If thermostat is battery powered, make sure fresh AA alkaline batteries
are correctly installed (see page 10).
