PDA | Installation and Operation Manual
b) Programmed Operation
The pump will go to the speed programmed. However, if the pool/spa heater, solar heat, or heat pump is on,
the pump will not go any lower than the pool/spa heater, solar heat, or heat pump speed setting.
c) Freeze Protection
In the Freeze Protect mode the pump will turn ON and be set to at least the freeze protect speed. If the Filter
Pump speed is higher than the Freeze protect speed, then the pump will run at the filtration speed. Also, if
speeds have been assigned to auxiliaries and if those auxiliaries are freeze protected, the pump will be set to
the highest of the speeds.
6.15.12 Auxiliary Pump Mode
a) Manual Operation
Setting speeds by turning ON auxiliaries that have speeds assigned to them.
1. The speed assigned to the auxiliary that was pressed takes precedence. For example, if the pump is at 3000
RPM, and then AUX 1 is pressed, the pump will switch to the speed that is assigned to AUX 1 regardless of
whether the speed is higher or lower than the speed that the pump is currently running at. So, referring to the
table below, if all of the auxiliaries are OFF and then AUX 3 is turned ON the pump will go to 3000 RPM.
Then if AUX 2 is turned ON the pump switches to 2000 RPM.
2. However, if you have several auxiliaries ON and all of them have a speed assigned to them, what speed does
the pump go to when you turn OFF one of the auxiliaries? The pump will switch to the highest speed that is
assigned to the auxiliaries. For example, referring to the table below, if all 3 auxiliaries are ON and the pump
is at 1000 RPM, what speed will the pump go to when AUX 1 is turned OFF? The answer is 3000 RPM, the
highest speed that is assigned to the auxiliaries that are ON.
AUX # SPEED ASSIGNED TO AUX
1 1000 RPM
2 2000 RPM
3 3000 RPM
Setting speeds from the VSP Adjust/Set Speed menu (accessed from the other devices screen).
1. Regardless of what speed is ON, the pump will switch to the speed depending on which one of the 8 buttons
on this screen is pressed.
b) Programmed Operation
Programming pump SPEEDS.
1. The pump will go to the speed that is being turned ON by the program regardless of what the speed currently
is. If a program time ends and there are other programs overlapping, the pump will go to the highest
programmed speed.
Programming AUXILIARIES that have speeds assigned to them.
1. The pump will go to the speed that is assigned to the auxiliary that is being turned ON, regardless of the
current speed. If several programs are overlapping for auxiliaries that have speed assigned to them, the pump
will operate at the speed of the auxiliary that was most recently turned ON.
2. If several programs are overlapping for auxiliaries that have speeds assigned to them, and then one of the
programs end, then the pump will switch to the highest speed of all the auxiliaries that are ON.
