JP5 - DAYS / HOURS FILTER LIFE COUNTER  
This setting will determine how the remaining filter life will be displayed on  
the screen. In the DAYS setting, the screen will count down the number of  
calendar days remaining before a filter change is recommended. In the (%)  
setting, the screen will count down the amount of percentage (%) of air filter life  
remaining before a filter change is recommended. Either option will display the  
visual bar graph.

Clean Cycle™ (Patent Pending) feature. This will assist in improving Indoor Air  
Quality by circulating and filtering the air by using the system's blower fan on a  
timed basis. Your heating and cooling systems will still work as they normally  
would. This Clean Cycle™ feature will ensure that the blower fan will run for a  
minimum of fifteen (15) minutes per hour every hour, even if there is no demand  
for either heating or cooling system activation (this includes when the System  
Mode Switch is in the OFF position). The 15 minute required run time is  
accomplished by monitoring the amount of time the heating or cooling system  
has already run the fan within the past hour based upon a total of three 20  
minute segments. If the required 15 minutes per hour of run time has already  
been met by running either the heating or cooling, there will be no additional fan  
run time made by the Clean Cycle™ feature.  
Thank you for your confidence in our product. To obtain the best results  
from your investment, please read these instructions carefully and thoroughly.  
You should become fully acquainted with this thermostat before installing it for  
usage. Follow the installation procedures carefully, and one step at a time. This  
will save you time and minimize the chance of damaging either the thermostat  
or the systems that it controls. These instructions may contain information  
beyond that required for your particular installation. Please save these  
instructions for future reference.

AIR FILTER LIFE COUNTER  
The air filter monitor feature tracks the total amount of fan run time to  
calculate the estimated remaining life of the filter or recommended calendar  
days. The LCD display shows the remaining filter life in an easy to view bar  
graph that can be set to display either days remaining, or percent (%) remaining  
(refer to the "SETUP OPTIONS" section for instructions on changing options for  
this feature). The default filter life is ninety (90) days. This duration may be  
altered by pushing the FILTER button on the front of the thermostat and using  
either the UP or DOWN buttons to cycle through the available choices of: 000,  
30, 60, 90, or 120 days. A selection of 000 will disable the filter counter  
completely and remove the bar graph from the display. When the filter usage  
timer has counted all the way down, it will indicate the need for filter  
replacement by displaying a flashing red box containing the words "FILTER  
CHANGE". If you are in the DAYS mode (which is default), the LCD will count  
down to zero (0) and then back upwards to indicate the amount of days over the  
recommended filter replacement time. If you are in the percent (%) mode, the  
LCD will count down to zero (0) and then back upwards to indicate the amount  
of percentage over the recommended filter usage amount up to 100 percent  
over. To reset the filter counter after replacing your filter, either press and hold  
the FILTER button for at least three (3) seconds, OR press the FILTER button  
once and then the UP or DOWN buttons to change to a different filter duration  
setting.

If the ambient temperature displayed on the LCD screen does not exactly  
match a nearby thermometer, or perhaps another thermostat in the home, the  
user has the ability to adjust or shift the displayed temperature. The displayed  
temperature can be altered by up to 5°F (or 3°C) in either direction. This  
adjustment is performed by first placing the System Mode switch to the OFF  
position, then by pressing and holding both the UP and DOWN buttons  
together for at least two (2) seconds, the lower (red) portion of the screen will  
display the word SET, and the default selection of zero (0). Press either the UP  
or DOWN buttons for the associated direction of change. Note: If no buttons  
are pressed within four (4) seconds, the thermostat will return back to normal  
run mode.  
The CAG111 is protected against normal static electric discharges.  
However, in extremely dry weather you should touch a grounded metal  
object before touching the CAG111 to minimize the risk of causing  
damage to the unit.

CLEAN CYCLE™ (PATENT PENDING)  
LUX's Clean CycleTM (Patent Pending) allows you to enable a forced air system  
to periodically flow air through your system's filter, cleaning the air in your home,  
even when heating or cooling is not being utilized. In CLEAN mode the fan  
maintains the pre-programmed minimum run time of fifteen (15) minutes per  
hour; it may run additional time as required to maintain temperature control.  
The algorithm used avoids additional fan run time when the 15 minute minimum  
has been met over the last hour through temperature control. Minimum fan run  
times are met by running one third of the hourly requirement at twenty (20)  
minute intervals. The minimum fan run time is 15 minutes per hour.  
SETUP OPTIONS  
NOTE: This thermostat is able to be installed and used without changing the

so that it is positioned on only one (1) of the metal pins, and not both. A change  
to ANY of the jumper settings will not be recognized by the thermostat until a
