INSTALLATION

Please read all instructions carefully before beginning installation.

Turn off electricity to the appliance before installing or servicing thermostat or any part of the system. Do not turn electricity back on until work is completed.

Do not short (jumper) across electric terminals on furnace or air conditioner to test the system. This may damage the thermostat and void your warranty.
All wiring must conform to local codes and ordinances.
The thermostat should be limited to a maximum of 1.5 amps; higher current may cause damage to the thermostat.
Your thermostat is a precision instrument. Please handle it with care.

TOOLS REQUIRED

#1 Phillips screwdriver (small)
Drill with 3/16-in. (4.8mm) bit
Wire stripper/cutter

THERMOSTAT LOCATION

On replacement installations, mount the new thermostat in place of the old one unless the conditions listed below suggest otherwise. On new installations, follow the guidelines listed below.

Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the floor, and in a room that is used often.
Do not install it where there are unusual heating conditions, such as: in direct sunlight; near a lamp, television, radiator, register, or fireplace; near hot water pipes in a wall; near a stove on the other side of a wall.
Do not locate in unusual cooling conditions, such as: on a wall separating an unheated room; or in a draft from a stairwell, door, or window.
Do not locate in a damp area. This can lead to corrosion that may shorten thermostat life.
Do not locate where air circulation is poor, such as: in a corner or an alcove; or behind an open door.
Do not install the unit until all construction work and painting has been completed.

Read instructions carefully before removing any wiring from existing thermostat.
Wires must be labeled before they are removed.
Do not allow wires to touch each other or parts on thermostat.
When removing wires from their terminals, ignore the color of the wires since they may not comply with any standard.

REMOVING THE OLD THERMOSTAT

Switch electricity to the furnace and air conditionerOFF; then proceed with the following steps.
Remove cover from old thermostat. Most are snapon types and simply pull off. Some have locking screws on the side. These must be loosened.
Note the letters printed near the terminals. Attachlabels (enclosed) to each wire for identification. Remove and label wires one at a time. Make sure the wires do not fall back inside the wall.
Loosen all screws on the old thermostat and remove it from the wall.

MOUNTING THE CAG1500

Strip insulation leaving 3/8 in.(9.5mm) bare wire ends and clean off any corrosion.
Fill wall opening with noncombustible insulation to prevent drafts from affecting the thermostat.

Be careful not to drop the unit or disturb electronic parts. Leave the door closed while the body is being removed from the base.
Remove the body from the thermostat's base by pressing the thumb latch at the bottom center of the unit and swinging the body away.
NOTE
If you are mounting the base to soft material like plasterboard or if you are using the old mounting holes, the screws may not hold. Drill a 3/16 in. (4.8mm) hole at each screw, and insert the plastic anchors provided.
Hold the base against the wall. Route the wires through the hole below the terminal block. Position the base for best appearance (to hide any marks from an old thermostat). Attach the base to the wall with the two screws provided.

CONNECTING THE WIRES

Wires must be trapped between black clamp and brassterminal.
Securely tighten all 7 electrical terminal screws.

These diagrams are provided for new installations or unreferenced wires.

COMPLETING YOUR INSTALLATION

See Setup Options to configure jumpers.
Install two new Energizer or DURACELL "AA" size alkaline batteries at this time. For instructions, see BATTERIES/MAINTENANCE.
NOTE: Remove sticker from display
Install your CAG1500 on its base. To do this hang the top of the unit by the tabs on the base, then snap the bottom of the unit into place. Do not use unnecessary force. If the body does not snap into place easily, remove the body, re-hang it from the tabs and try again.
Turn the power back on to your heating and/or air conditioning system.
Verify that the system and its fan are operating properly. When set to ahigh temperature, the heating system should provide warm air after a short time. Likewise, a cooling system should provide cool air after a short time. Usually sound from the furnace and air conditioning units can be heard while they are running. The rush of moving air should be heard within a short time after either has been started.
Your installation is now complete.

warning NOTE
If you have an electric system and the blower does not operate after installation, find the electric/gas heat jumper on the back of the body. Move the jumper to ELEC and perform a HARDWARE RESET.

OPERATING INSTRUCTIONS

The CAG1500 alternately displays the current time and the room temperature. It also displays the day of the week and the current program period, MORN, DAY, EVE, or NITE. Set temperatures are indicated in the right side of the display.
You can make program or setting changes with the thermostat body on the wall, or conveniently removed from its base plate.

SYSTEM MODES

The Mode switch has three positions HEAT, OFF, and COOL. In the winter, set the system switch to HEAT to control your heating system. In the summer, set the switch to COOL to control your air conditioner. In spring and fall or when the windows are open, you can set the switch OFF.

UP/DOWN/CHANGE ARROW KEYS

There are two arrow keys just right of the unit's display. They are used to adjust set temperatures and change other settings.

TEMPERATURE ADJUSTMENT

Pressing an arrow key once adjusts the set temperature by one degree in the associated direction. Holding the key will automatically advance the setting in the associated direction.

CHANGING OTHER SETTINGS

If there are many choices for a value, usually that setting will automatically advance by holding one of the arrow keys. Some settings though, must be changed one press at a time.

DISPLAY ILLUMINATION

Press the light bulb button to illuminate the display. Pressing other buttons will keep the display illuminated until no button has been pressed for approximately 20 seconds.

FAN MODES

The fan switch has three positions AUTO, CLEAN, and ON. Setting the FAN switch to AUTO automatically runs your system's fan as required only for heating and cooling. The CLEAN position insures that your system's fan runs at least the programmed minimum duty cycle. The default duty cycle requires it to run 15 minutes every hour. Setting the FAN switch to ON runs your system's fan continuously. The FAN icon will flash whenever the fan is running.

warning NOTE
The FAN switch works only if your system provides a wire for the CAG1500's "G" terminal.

Repeat programming for each remaining day.
Rotate the dial back to RUN to accept all current values and end the programming session.

AIR FILTER USAGE MONITOR

The AIR FILTER USAGE MONITOR counts the number of days a filter has been in use. In RUN mode, the display shows the remaining filter life via a bar-graph, and the number of DAYS LEFT in the 3 digit filter display area.

CHANGE FILTER will appear when the days remaining has reached zero and the filter should be changed. DAYS OVER is indicated when a filter change is past due. The filter counter can count up for days over from 000 to 999 days.

SETTING THE AIR FILTER LIFE
This value sets the number of days to be counted before a filter change is indicated.

To set the AIR FILTER USAGE LIMIT:

Rotate dial to AIR FILTER.
LCD shows: SET LIMIT at lower left, with current setting at center screen.
With a new filter installed, use the UP/DOWN keys to change this value to the number of days of useful filter life specified by your filter manufacturer. The available settings are: 000, 30, 60, 90, and 120 days. The default air filter life setting is 90 days. A selection of 000 days will disable the Air Filter Counter feature completely, and hide both the "number of days" and the "bar graph" items from the red lower portion of the display.
The counter for the Air Filter Usage Monitor is automatically reset back to zero when the usage limit setting value has been changed.
Return the dial to the RUN position when finished.

RESETTING AIR FILTER COUNTER

To reset the air filter counter when you replace your filter:

Press and release COPY to reset counter
Press and release COPY again to restore previous count.
Return the dial to the RUN position when finished.

TEMPERATURE OVERRIDE

OVERRIDE allows you to change the current SET TEMPERATURE in HEAT or COOL until the next program period without changing your temperature control programs.

Press UP/DOWN to change the current temperature setting. The OVERRIDE indicator appears on display.
The OVERRIDE will be canceled at the start of the next program period, and the temperature setting will return to its programmed value.
An OVERRIDE may be terminated by rotating the dial, switching the mode to OFF, or initiating a HOLD.
Adjusting the set temperature to its program value will also cancel an OVERRIDE.

TEMPERATURE HOLD

HOLD may be used for manual temperature control. HOLD is the simplest means to set and maintain a fixed temperature. It allows you to set and maintain a fixed temperature indefinitely in Heat or Cool without concern for programming. To initiate a HOLD:

Press and release HOLD.
Adjust temperature as desired with UP/DOWN.
Temperature setting will not change until the HOLD is cancelled.
To cancel a HOLD, press and release HOLD again, rotate the dial, or switch mode to OFF.

ADVANCED FEATURES

TEMPERATURE SWING

A thermostat works by turning your heating or cooling system on or off whenever the room temperature varies from the set-point temperature. This variation is the "swing." Your system should cycle on about 3 to 6 times per hour. A smaller swing number increases the number of cycles, so room temperature is more constant. A larger swing number decreases the number of cycles, but saves energy in most cases.

SWING SETTING

Rotate dial to the AIR FILTER position.
Simultaneously press NEXT & HOLD.
Use UP/DOWN keys to change swing.
Choices are 1 through 9. The default is 2.
Rotate the dial to the RUN position to finish.

TEMPERATURE CALIBRATION

Rotate the dial to SET DAY/TIME.
Simultaneously press NEXT & HOLD.
Use UP/DOWN keys to adjust the thermostats calibration by as much as ± 5°F (± 3°C).

LOCK

LOCK
To prevent tampering, press NEXT NEXT NEXT HOLD. This sequence of keys will lock and unlock the set temperature, programs and other settings. When the keys are locked, a padlock icon will be visible above the time and temperature display. The Lock will be disabled after a Hardware Reset.

SETUP OPTIONS

JUMPER SETTINGS
There are four jumpers, each controls a setting depending on its position.

GAS/ELECTRIC MODE - J4
The position of this jumper controls when the thermostat requests the system fan to run. In HEAT mode with the gas jumper in place, the fan is controlled by the heating system itself. In HEAT mode with the jumper open or removed, the fan is controlled by the thermostat.

5MIN/2MIN MINIMUM RUN TIME - J3
The position of J3 sets the minimum length of time that the thermostat must remain with Heat or Cool either on or off before it will automatically switch to the alternate On or Off state. This feature prevents short cycling and provides compressor protection for cooling units. Choices are 2 or 5 minutes.

TEMPERATURE DISPLAY FORMAT °F/C - J2
The position of this jumper controls whether temperature is displayed in degrees F° or C°

TIME DISPLAY FORMAT 12/24 HR CLOCK - J1
The position of this jumper controls whether time is displayed in 12 hour or 24 hour Military Time format.

REPOSITIONING JUMPERS
To change a setting, the jumper must be repositioned and a HARDWARE RESET must be performed. These jumpers are located inside the thermostat on the rear of its circuit board. To access them, remove the unit from the wall by pressing up on the thumb latch at the bottom of thermostat and swinging the body out and away.

	OPEN	CLOSE
J4	ELECT	GAS
J3	2MIN	5MIN
J2	C	F
J1	24HR	12HR

The table pictured on the right is also printed on the circuit board. The closed or shorted position is that which covers both a jumpers pins. To prevent its loss, a jumper may be placed over one pin only for the open positions. After settings have been changed, press S8, the HARDWARE RESET button for the changes to take effect. See HARDWARE RESET

BATTERIES AND MAINTENANCE
