Assigning a Local Max Speed to a Slave
To assign a unique maximum speed setting to an individual
slave pump, hold the SET button on the slave until a bright
LED shows on the LED strip. This LED represents the locally
assigned maxi-mum speed for this slave pump.
To increase the maximum speed, turn the knob to the right.
To decrease the maximum speed, turn the knob to the left.
If you would like to restore the slave pump’s speed setting to
match the master pump’s speed setting, hold the SET button
until the brightly illuminated LED showing the max speed
goes dim. It will now revert back to always match the speed
input by the master pump.
Next, turn the knob to adjust the maximum speed for that
particular slave pump, which will be indicated by the LED
strip.
While normally you cannot change the speed of a slave pump, because the speed is determined entirely
by the master pump, with the EcoSmart driver you now have the ability to control the maximum speed
of individual slave pumps independently from the master. This will come in handy if your aquarium setup
requires higher flow in most areas but lower flows in other areas such as if a slave pump is used to
provide spot flow to a delicate coral, or if it is used on the back of a narrow tank. In the default setting, a
slave pump will always do exactly the same thing or the inverse of the master pump (based on whether
it is set to Sync or Anti-Sync), and therefore the maximum speed that a slave pump can achieve is
governed by the master pump.
