POWER FOR MAINTENANCE (repairs, removing broken
bulbs, etc.). ALWAYS TURN POWER OFF AT THE
SERVICE PANEL BY REMOVING A FUSE OR CIRCUIT
BREAKER BEFORE DOING ANY CIRCUIT REPAIRS.
(2) In case of a conflict (for example you have programmed
the timer to be on at 4 pm every day of the week and also
programmed the timer to be off at 4 pm on saturdays) the
higher program number is followed. In case of a conflict
within a program number Off is followed rather than On.
