Automatic Reduced Speed Selection

The imPower motor has been programmed with a feature called the Automatic

Reduced Speed Selection function that allows for the maximum energy savings

via multi-speed operation despite using a standard single-speed timer. This

feature also applies to a multi-speed timer where the Circuit 2 speed can either be

assigned to medium or low speed.

The reduced default speed is factory set to switch to low speed operation after the

initial two-hour high speed operational period. However, it can be modied to

medium speed as required by minimum ow / pressure requirements of various

pool-side equipment / features as dened by manufacturer specications. The

default speed should only be modied during the rst two minutes of applying

power to the unit.

Please follow all local/state regulations regarding pool motor and timer speed

settings when choosing default reduced speed operation.

Step 1: Allow the pump to achieve prime if starting the system for the rst time.

Step 2: Turn power to the motor o at the timer / controller once pump prime

is reached. Also turn power o to the motor if prime was previously

reached and now motor/pump are operating as dened by the timer.

Step 3: Turn the motor on after allowing the motor to sit for at least 30 sec-

onds. Ensure that HIGH speed / Circuit 1 is being commanded if using a

multi-speed timer.

Step 4: After allowing the motor to come

to full speed, press and hold the

high and medium buttons simulta-

neouslyasshowninFigure18until

the low speed LED indicator light

begins to blink and then release.

Step 5: The low speed LED will continue to

blink for three seconds to indicate a

modication to the automatic

reduced speed turndown is being requested. After a brief pause, a sec-

ond series of LED blinks will indicate the new default setting has been

set to either medium speed (medium speed LED blinks) or low speed

(low speed led blinks).

Step 6: Turn the motor o, wait 30 seconds, turn back on to activate new setting.
