Installations including a Dimmer:
• The load size and type must not exceed the rating of the dimmer.
(Typically 600 watts, 120 VAC, 60 Hz, incandescent lamps only.)
• If the dimmer is placed in it’s ‘OFF’ position, the timer cannot operate the lights.
• If the dimmer is set too low, the lights may not turn back on under timer control. If necessary, use a
• If the dimmer is set too low, the lights may not turn back on under timer control. If necessary, use a
premium quality dimmer that can be turned on at very low settings.
Multi-switch installation using a dimmer :
A 3-way dimmer should not be used. If a multi-switch installation is required, use the following diagram.
NOTE: For new construction or to replace a dimmer switch, a lighted switch, or a 3-way switch without screw
terminals, a single pole switch can be used at the remote location, as shown below.

Special applications
Because of it’s unique “hard contact” switch feature, your timer may be used for applications not previously possible
for electronic wall timers, such as use with dimmers, use without utility power, use on circuits other than 120 volts,
controlling relays or contactors, or to control DC voltage (for example in recreational vehicles). See instructions
above for dimmer applications. For DC and high voltage applications please note the reduced load ratings on prod-
uct label. Consult factory for application details.
