(optional if AC powered).
AC Power
The thermostat can be powered by 24
VACpower, or by batteries.
To wire the thermostat {k)rAC power,
connect the coilln-lon side of the
cooling tmnsfbrmer 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 o_, 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 11).
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.

CAUTION: EQUIPMENT DAMAGE HAZARD
Compressor protection (minimum off time) is bypassed during testing. To prevent
equipment damage, avoid cycling the compressor quickly.

Installation Guide
Auto Changeover is a feature used in
SystemAuto climates where both air conditioning and
heating are used on the same day.When the
system is set to Auto, the thermostat auto-
matically selects heating or cooling depend-
ing on the indoor temperature.
Heat and cool settings must be at least 3
degrees apart.The thermostat will automatical-
ly adjust settings to maintain this 3-degree
separation (called "deadband").
The 3-degree separation between heating
and cooling set temperatures is fixed, and
cannot be changed.
Adaptive Intelligent Recove W eliminates guesswork when setting your schedule. It
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 th_e.
For example: Set the Wake tfllle to 6 am, and the temperature to 70°.The heat will
come on before 6 am, so the temperature is 70 ° by the time you wake at 6.
This feature helps prevent damage to the
compressor 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 before restarting.
Message flashes until safe
restart time has elapsed
During the wait time, the message Cool On
or Heat On (heat pumps only) will flash on
the display.When the safe wait time has
elapsed, the message stops flashing and the
compressor turns on.
