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 examples for the most common
uses . For other ideas call the toll free Tork Tech Help
