What schedule should I use on a Woods 50016?

Set ON three to four hours before departure and OFF at departure. For a 7:30 a.m. commute, 4:00 a.m. ON and 7:30 a.m. OFF is a practical deep-cold schedule.

Why does the Woods timer stay on?

Check whether the manual override is in ON rather than AUTO, confirm the displayed day and AM/PM, and review every stored program for an overlapping ON period.

Will it remember the program after an outage?

Models and internal backup condition vary. Verify the current clock and AUTO mode after a long outage instead of assuming the schedule survived.
