These time switches provide a different “ON/OFF”
program each day of the week. They also provide for 4 pole single throw and 4
pole (2NO/2NC) switching. This series provides true 7-day load control with
minimum ON and minimum OFF times of 3-1/2 hours. The “BC” models with carryover
provide a carryover of 16 hours minimum to maintain accurate load control even
during power failure. When power resumes, the carryover automatically rewinds
itself. Only 1 hour is required to rewind the carryover for each 2 hours of
