timer programming
1. Set the current time by turning the programming ring clock-
wise until the timing arrow points to the current time of day.
2. Restore power to the circulator and set the manual switch on
the timer dial to the "on" position ("i").
3. Set the required "on/o" times by pushing the program-
ming tabs to the outer position for "on" time intervals. For
"o" ("o") operation keep the programming tabs in the
inner position.
4. Set the manual switch to the center position, between the
"i" and "o" on the timer dial in order to cycle the pump ac-
cording to the programming tab settings. The pump will run
continuously when the switch is set to "i" (on) position. The
"o" (o) position of the switch will shut the circulator o at
all times.
5. In the event of power outage, the timer must be adjusted for
the correct time of day after power is restored.
Note: The 24-hour timer requires manual resetting for day-
light savings time.
