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.

12.Your installation is now complete.

RC RH

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.

NOTE: If you have an Electric Heat system and the blower does not operate

after installation, locate the "Gas/Electric" option inside the back of the

thermostat. Move the jumper to the "Electric" position.

CLEAN CYCLE™ (PATENT PENDING)

LUX's Clean Cycle^TM(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.

1. To access your unit's battery location, remove the front half of the thermostat

from its base plate by applying opposite pressure on the two thumb tabs

located on the bottom edge of the thermostat and separate the unit.

2. The battery tray is located adjacent to the circuit board.

3. Remove the used batteries from the battery tray (if present) and install two

JUMPER SETTINGS

If “Y” and “C” are both present,

There are five (5) headers (or jumpers) located inside the thermostat at the

rear of the circuit board. These settings can be changed from their default

values by removing its corresponding black jumper cap and reinstalling the cap

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

HARDWARE RESET is performed. An OPEN jumper means the cap is only on

one (1) metal pin, and a CLOSED jumper

servicing the thermostat or any part of the system. Do not

turn the electricity back on until the work is completed.

4. Install your CAG111 thermostat back onto its base plate. To do this, line up

the tabs on all four corners and gently push the unit straight onto the base. Do

not use unnecessary force if the body does not snap into place easily. Remove
