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.
1. Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the
floor, and in a room that is used often.
2. 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.
3. 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.
4. Do not locate in a damp area. This can lead to corrosion that may
shorten thermostat life.
5. Do not locate where air circulation is poor, such as: in a corner or an
alcove; or behind an open door.
6. Do not install the unit until all construction work and painting has
been completed.

9.  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.
10. Turn the power back on to your heating and/or air conditioning system.
11. Verify that the system and its fan are operating properly. When set to a
high 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.
12. Your installation is now complete.

N O T E

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.

MOUNTING THE CAG1500

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.

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.

CLEAN AIR CYCLE.

The 

CLEAN AIR CYCLE

insures that the fan runs for at least the specified

duration each hour to circulate and filter the air in your home. Hourly fan run
time may be specified from 9 to 60 minutes per hour."60" = ON or
continuous run. The default minimum run time is 15 minutes total per hour.
Additional fan run time is not called for when the heating or cooling
requirement exceeds the threshold setting. When additional fan run time is
required, it is met by running the fan at 20 minute intervals, for 1/3 the hourly
run time setting. 

EDITING CLEAN CYCLE PROGRAMS

1. Turn rotary dial to

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.

AIR FILTER

position.

2. Simultaneously press 

NEXT & HOLD

.

3. Use 

UP/DOWN

keys to change swing.

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 

or 

TIME DISPLAY FORMAT 12/24 HR CLOCK - J1
