1. Follow the installation steps in both sections and see

Figure 3 for wiring connections.

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.
