When Installing this Product...  
1.  
Read these instructions carefully. Failure to follow the  
instructions can damage the product or cause a hazard-  
ous condition.  
2.  
3.  
4.  
Check the ratings given in the instructions to make sure  
the product is suitable for your application.  
Installer must be a trained, experienced service  
technician.  
After completing installation, use these instructions to  
check out the product operation.  
Installing Wallplate  
CAUTION  
Electrical Hazard.  
Can cause electrical shock or equipment damage.  
Disconnect power before wiring.  
Selecting Location  
Install the thermostat about 5 ft. (1.5m) above the floor in an  
area with good air circulation at average temperature. See  
Fig. 5.  
The thermostat can be mounted horizontally on the wall or on  
a 4 in. x 2 in. (101.6 mm x 50.8 mm) wiring box.  
1.  
2.  
3.  
Position and level the wallplate (for appearance only).  
Use a pencil to mark the mounting holes.  
Remove the wallplate from the wall and, if drywall, drill  
two 3/16-in. holes in the wall, as marked. For firmer  
material such as plaster, drill two 7/32-in. holes. Gently  
tap anchors (provided) into the drilled holes until flush  
with the wall.

Battery Tips  
1.  
2.  
3.  
Replace the batteries as soon as LO Batt flashes in the  
display. The LO Battery indicator flashes in the display  
one month before the batteries run down completely.  
Always use fresh AAA alkaline batteries. Non-alkaline  
batteries do not last as long and can leak, causing  
thermostat damage.  
Although the thermostat has a Low Battery indicator,  
replace the batteries once a year to prevent the thermo-  
stat and heating/cooling system from shutting down due  
to lack of battery power.  
M22430

Remove the old batteries and insert three fresh AAA  
alkaline batteries, as marked on the thermostat.

The thermostat microprocessor-based control requires that  
the user understands temperature control and thermostat  
performance. A conventional mechanical or electronic  
thermostat does not control temperature precisely at setpoint.  
Typically there is an offset (droop) in the control point as the  
system load changes. This is a phenomenon that most people  
in the industry know and accept. Many factors contribute to  
offset including switch differential, thermal lag, overshoot,  
cycle rates and system load.

offset. This makes temperature control more accurate than  
the conventional mechanical or electronic thermostats. The  
temperature control algorithm is called proportional plus  
integral (P+I) control.  
Temperature Recovery  
The thermostat feature, Adaptive Intelligent Recovery™,  
eliminates all guesswork when setting the thermostat  
schedule.  
The thermostat sensor, located on the thermostat or remote,  
senses the current space temperature. The proportional error  
is calculated by comparing the sensed temperature to the  
programmed setpoint. The deviation from the setpoint is the  
proportional error.  
Simply set the program schedule to the time that the comfort  
temperature is desired. The thermostat then turns on the  
heating or cooling at just the right time to have the home  
reach the scheduled temperature at the scheduled time.  
The thermostat also determines integral error, which is a  
deviation based on the length of error time. The sum of the  
two errors is the (P+I) error. The cycle rate used to reach and  
maintain the setpoint temperature is computed using the P+I.  
The additon of the integral error is what differentiates the  
thermostat from many other electronic and mechanical  
thermostats. See Fig. 31.  
For example—get up at 6:00 AM and want the temperature to  
be 70°F. Set the Wake period for 6:00 AM and 70°F. The  
thermostat then turns on the heat before 6:00 AM to raise the  
temperature to 70°F by 6:00 AM.

extremely high humidity conditions, the thermostat keeps the  
air conditioner running (energizing Y and G) for up to 3°F
