Refer to product label for maximum ratings for various voltages and load types.
Introduction
The timer can replace your regular or 3-way light switch (where two switches control the same light) to control
lights for security, or can control an outlet to switch most 120VAC loads up to the maximum rating on the
timer label. The timer can control incandescent lights, fluorescent lights, flood lights (PAR lamps), stereos, or
appliances such as an air conditioner. The timer can also control many loads 12 to 277 VAC and 12 to 28 Volts
DC. Timer may not be used with lighted switches.
You will need to use a Decorator style wall plate with this timer (not supplied).
The installation instructions on this page are for replacing a light switch (or 3-way light switch) with the timer. See
"Other Installations" on the next page for wiring diagrams for new construction, switching from 3 or more loca-
tions, or using the timer with a dimmer.
Installation Instructions - Single Switch or 3-way - to replace an existing switch:
1.TURN OFF POWER by REMOVING FUSE or turning
7/16"
the CIRCUIT BREAKER OFF.
2. Remove the existing wall switch.
Prepare the ends of the building wiring as shown.
Trim building wires bare to 7/16".

3. Connect one of the building wires to the black wire
from the timer, using the wire nuts provided. Connect
the other building wire to the blue wire from the timer.
THE RED TIMER WIRE IS NOT USED FOR SINGLE
SWITCH INSTALLATIONS. Cap the red wire with a
BLUE WIRE
wire nut.
BE SURE THAT ALL THE WIRE NUTS ARE SECURE.

Battery Replacement
The 1.5 VOLT alkaline battery should operate your timer for 1

/
years or more under typical conditions. High
2
or low temperature or frequent use of the manual pushbutton or the 3-way switch will reduce the battery life.
Replace the battery when the digital display is dim, the message 'lobAt' (Meaning LOW BATTERY) is displayed,
or if the timer fails to operate. Press any button to clear the 'lobAt' message. The timer has built-in memory
protection providing at least 15 seconds to change a weak battery without losing your settings. You do not
need to turn off the load or the power in order to replace the battery, however, do not attempt to switch the
timer on or off while the battery is out or your settings will be lost and the timer will need to be reset.
Programming and Operating Instructions
Introduction to Operation and Programming:
The timer is a programmable switch.
At any time you can push the clear cover/switch to manually turn the switch ON or OFF, unless selected mode is
CLK or PGM.
You can program up to 12 ON/OFF EVENTS; times when the timer automatically switches the connected lights
(or other electrical devices) ON or OFF (up to 6 ON events and 6 OFF events). An EVENT can be set to switch at:
• any specific time, and day of the week,
• a specific time every day,
• a specific time on weekdays, or
• a specific time on weekends.
See Installation Instructions first if your timer is not already installed, or if the AAA Alkaline battery is not
installed.
Manual Override
Works like a light switch. Push and release the clear cover/switch
(area over buttons) to switch ON or OFF. Or switch ON and OFF
using the remote switch(es) in multi-switch installations.

LOAD MAINTENANCE
WARNING1 DO NOT USE THE TIMER TO TURN OFF POWER FOR MAINTENANCE (repairs, removing broken
bulbs, etc.). ALWAYS TURN POWER OFF AT THE SERVICE PANEL BY REMOVING A FUSE OR SWITCHING OFF
A CIRCUIT BREAKER BEFORE DOING ANY CIRCUIT REPAIRS.
Error Messages
The 'lobAt' message means the battery is low and needs to be replaced. Uses one standard AAA alkaline battery.
The display is 'noOp' (Meaning no Operation) if the timer fails to operate. This can happen in very cold tempera-
tures. Normal timer operation should resume at normal temperatures. Press any button to clear the message(s).
If the 'noOp' remains at normal temperatures with a fresh battery, timer needs repair.
