INSTALLATION

Your Timer replaces a standard light (toggle) switch. It fits into a wall box easily and uses the same wires as the switch you took out. If you can install a light switch, you can install the Timer.

Single Pole (has two black wires)

Three Way (has one red, blue and black

Supplied:

Wire nuts (2 or 3)
outlet box screws (2)
black control panel screw (1)
control panel screw (1)
Jumper wire (1) (three way only)

Tools needed:

Step by Step Installation:

1. TURN POWER OFF to the wall switch by removing fuse or turning off circuit breaker.
2. Remove switch plate and pull the existing switch out.
3. Carefully pull off the pushbutton (time dial) 3a and remove the cover assembly from timer 3b.
   
4. Note: If the old switch has a ground wire (normally a bare wire connected to a green hex head screw) fasten it securely to metal box or to timer metal bracket.
   1. Single Pole Disconnect wires from old switch and connect them to the Timer. Use wire nuts provided.
      
      
      Go to step 6 below
   2. Three Way Identify the "common" wire. (The common terminal normally has a different color screw, or is marked on the old switch. The common wire is the power wire and is usually black.)
      
      
      Connect common wire to black timer wire (use wire nut) a. Connect the other two wires to the red b and blue c timer wires (use wire nuts).
      Three way wiring diagram for old wiring (using the existing 3-way switch)
      
      Three way wiring diagram for new wiring or when existing remote switch was a dimmer, lighted or back wired switch (a standard single pole switch is used for the remote switch).
      
5. Three Way continued (at the second three way switch)
   Note: These instructions use trial-and-error to figure out how to install the jumper wire.
   1. Be certain power is off.
   2. Remove switch plate and pull the existing switch out.
      Note: If the existing switch is a dimmer, illuminated switch or back wire pressure terminal switch: Replace it with a standard (single pole non-dimmer) switch. Identify the "common" wire. Attach the common wire together with one of the other wires, to either screw terminal. Attach the remaining wire to the other screw terminal.
   3. Identify the "common" wire. (The common terminal normally has a different color screw, or is marked on the old switch. The common wire is the power wire and is usually black.)
      
   4. Loosen the common terminal just enough to add one end of the jumper wire. Retighten.
   5. At either of the other two terminals 5a or 5b, loosen the terminal just enough to add the other end of the jumper wire. Retighten.
   6. Re-install the switch (do steps 6 - 8 below to install the timer).
   7. If the timer and remote switch do not turn the light on and off correctly, repeat steps 1 and 2 of 5 (above).
   8. Leave the jumper attached to the common terminal. Switch the jumper to the other of the two remaining terminals.
   9. Re-install the switch.
6. Mount the timer into the wall box. Be careful not to cut the wires on the edges of the box. Use 2 outlet box screws provided.
   
7. If using a decorator wall plate do 8a and 8b. If using a regular wall plate do 8c.
   If neither AM nor PM is centered in its window turn the gear with your finger.

8a. Install the decorator wall plate with screws provided with the decorator wall plate.

8b. Mount the timer plate:

1. Insert the indicator rod into its hole.
2. Insert the black timer screw.
   
3. Insert the timer screw.
   

8c If using a regular wall plate:

1. Don't use the screws provided with the wall plate.
2. Insert the indicator rod through the top hole in the wall plate and into its hole.
3. Insert the black timer screw through the toggle switch hole.
   
4. Insert the timer screw.
   
5. Install the pushbutton time dial. Rotate it two turns to make sure AM/PM indicator works.

1. Move the control lever to ON.
2. Push and release the pushbutton. The light should turn on.
3. If a 3-way installation, check that the remote switch also turns the light on and off. If not go to step 5 -7 above and switch the jumper wire.

PROGRAMMING

Telling the timer when to turn the lights on and off (programming) can be done 2 ways.

In Rapid Programming you set all the on/off times in just minutes.

In 24 hour self programming simply use the timer as a light switch for 24 hours and the timer 'remembers' those settings and repeats them red indicator automatically.

Rapid Programming

1. Move control lever to OFF-CLEAR for at least 5 seconds

• red indicator light goes off
• all time settings are erased.

2. Move control lever to ON.

• red indicator light will start flashing.

3. Check a clock; then turn pushbutton time dial clockwise at least one click.

• stop at the half hour nearest to present time (note AM or PM).
  Note: When turning pushbutton time dial, do NOT accidentally PRESS at the same time.

4. Press pushbutton time dial once to enter presenttime.

• red indicator light goes off (present time has been recorded).

5. Turn pushbutton time dial clockwise to desired ONtime.

• red indicator light blinks with each click.

6. Press pushbutton to enter ON time.

• controlled light(s) will turn on.

7. Turn pushbutton time dial clockwise to desired OFF time.

• red indicator light blinks with each click.

8. Press pushbutton time dial to enter OFF time.

• controlled light(s) turn off.

9. Repeat 5-8 for other on/off times.
10. Turn pushbutton time dial for at least 2 more turns from the first ON time to complete this program

• red indicator light will turn on and stay on (steady light means timer is in automatic).
  Note: Pushbutton time dial does not turn automatically after settings to indicate time of day.

24 Hour Self Programming

1. Move control lever to OFF-CLEAR for at least 5 seconds

• red indicator light goesoff
• all time settings are erased.

2. Move control lever to ON.

• red indicator light will start flashing.

3. Turn light(s) on and off as you normally would during a 24 hour period.

• When you turn lights on the first time, the red indicator light will go off and stay off.
  Note: Each on/off period must be at least 30 minutes. If you turn light(s) off or on in less than 30 minutes, RED INDICATOR will resume FLASHING.
• After 24 hours, your Timer will be fully programmed, red indicator will stay ON and timer will automatically repeat the lighting pattern you entered during the 24 hours.

Program Review

Program Review lets you check the ON/OFF settings in Timer memory without erasing them.

1. Timer must be in AUTOMATIC mode

• red indicator light on and steady.

2. Turn pushbutton time dial clockwise at least one click.

• Stop at the nearest half hour to present time (Note AM or PM).

3. Push pushbutton time dial once to start review.

• red indicator light goes off.

4. Turn pushbutton time dial clockwise slowly

• red indicator will flash with each click.
• lights turn on and off at programmed times
• watch the time on the pushbutton time dial.

5. Press pushbutton time dial once to end review.

• red indicator light turns on and stays on.
• timer returns to automatic mode.

MANUAL OPERATION

Push the pushbutton time dial quickly twice to switch to manual operation.

• The stored program remains.
• The red indicator light goes off.
• Lights can be turned on or off by pushing the pushbutton time dial.

Push the pushbutton time dial quickly twice to return to automatic operation.

• The red indicator light is lit and steady.

TIMER IS ALWAYS A LIGHT SWITCH

With the Timer in automatic.

• The red indicator light is lit and steady.
• Push the pushbutton time dial to turn lights on or off. The automatic program is not changed. Lights will still turn on (or off) at the next programmed setting.

BURNED-OUT BULBS

If a bulb controlled by your Timer should burn out, the red indicator light will go off. To restore normal operations, move control lever to OFF-CLEAR and replace light bulb. Re-program timer.
