SETTING THE CLOCK/TIMER
1. Rotate the dial in a clockwise direction until both the time
shown, and the appropriate AM or PM indicator, correspond
to the current time of day. (This adjustment is required for
initial operation, following a power interruption, to adjust for
daylight savings time, or for periodic time correction.)
2. Remove the clear plastic cover from the dial.
3. The outer ring of the dial has an adjustable tab for each 15
minute time interval of a 24 hour day. To enable circulator
operation for a specific time interval, slide the corresponding
interval tab toward the perimeter of the dial. All tabs
positioned toward the center of the dial disable circulator
operation for those time intervals.
4. Verify the manual override switch is in the “AUTO” position.
5. Replace the clear plastic cover on the dial.
