It is important to note that after a power outage, the timer will resume the program based on the state it was in before the outage. For example, if a cycle program of “on for 5 minutes, off for 10 minutes” was interrupted during the 3rd minute of the “on” cycle, the timer will resume by starting the “on” cycle from the beginning when power is restored, and similarly for the off period. 4. We suggest hanging the timer vertically with the bottom outlet pointed towards the ground and at least 2ft above the ground for maximum weather resistance. Also, additional measures to protect the timer from heavy rain or snow are recommended as the bottom outlet of the timer is not 100% weatherproof due to its structure. 5.
