Planning Your Program
The single channel unit will operate as a standard
timer for typical indoor or outdoor control needs. Only
if a photo sensor is connected can it operate with a
photo and time logic.
Two channel units allow you to set-up different control
logic for each channel by using the Select Switch. To
meet Title 24 requirements, one channel could be
sunset to sunrise while the other channel is sunset
to time OFF. Also one channel could be used for indoor
lighting control with fixed ON and OFF times while the
other channel is set for sunset to sunrise.
The photo sensor will only operate when the program is
set to ON. Here are samples for the most common
uses. For other ideas call the toll free Tork Tech Help
Line 888-500-4598.
1. Sunset ON and Sunrise OFF 7 days a week:
Program the channel for an ON event at 12:00am
Monday through Sunday. The photo sensor will take
full control and turn on the load ON only when light
level drops to the preset footcandles then turns OFF
when the light level is twice the preset footcandles.
