TIMER PROGRAMMING
1. Adjust the programming ring on the unit by turning it in the
direction of the rotation arrow until the timing arrow points
to the actual time of day. (This can also be accomplished
by rotating the minute hand on the real time clock, (shown
in figure 5) clockwise, until both the real time clock and the
timing arrow indicate the actual time of day.)
2. Restore power to the circulator and set the switch on the
timer dial to the “
I
” (ON) position.
3. Program the “ON/OFF” times by pushing the programming
tabs toward the center of the dial for “OFF” operation and
toward the outside of the programming ring for “ON” time
periods. A pencil, pen or similar object may be used in
making adjustments to the programming tabs.
4. Set the manual switch to the “TIMER” position, which is
centered between the “
I
” and “O” on the timer dial, in
order to cycle the pump according to the programming tab
settings. The pump will run continuously when the switch
is set to the “
I
” (ON) position. The “O” (OFF) position of the
switch will shut the circulator off at all times.
5. In the event of a power outage, the timer must be adjusted
for the correct time of day after power is restored.
