REMOVING THE OLD THERMOSTAT

1. Switch electricity to the furnace and air conditioner OFF; then proceed with the following steps.

2. Remove cover from old thermostat. Most are snap-on types and simply pull off. Some have locking screws on the side. These must be loosened.

3. Note the letters printed near the terminals. Attach labels (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.

4.  Loosen all screws on the old thermostat and remove it from the wall.

MOUNTING THE CAG1500

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

CAUTION
Be careful not to drop the unit or disturb electronic parts. Leave the door closed while the body is being removed from the base.

3. 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.

4. 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

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

These diagrams are provided for new installations or unreferenced wires.

All COMMON WIRES MUST BE TAPED OFF.

  * If “Y” and “C” are both present, “C” is a common wire. DO NOT USE “C”! TAPE IT OFF!
  * If a “B” wire in your system is a system common, then connecting it at the “B” terminal may cause damage to your system. TAPE IT OFF!

COMPLETING YOUR INSTALLATION

7. See Setup Options to configure jumpers.

8. Install two new Energizer or DURACELL “AA” size alkaline batteries at this time. For instructions, see BATTERIES/MAINTENANCE.
   NOTE
   Remove sticker from display.

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.

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.

NOTE
The FAN switch works only if your system provides a wire for the CAG1500’s “G” terminal.

• 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

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

TEMPERATURE CALIBRATION

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

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.

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
