Can I control the pump speed when solar turns on?

I have an easytouch 8 (first gen) and a superflo vs pump with the autmation cable and two speeds hooked up to relays (aux 6 and 7.) I also have solar hooked up to the easy touch and when the solar turns on the eash touch activates a valve to divert the water to the roof.
Can I somehow set the pump speed on aux 7 to run when solar is called? I see some references to this with a solartouch in another post, but would rather not have to purchase that.
 
E,

Yes... If you unplug the Aux 7 relay from Aux 7 connection and plug it into the Solar (booster pump) connection J17, then when the solar valve turns, it will turn on your Aux 7 relay (Now the Solar relay).

Thanks,

Oops, I misremembered which connection was j17. They are not labeled in the manual, but I see that solar booster connection. It's kind of strange they do not address these 4 connections in the manual.
I'll try it out today. Thanks!
 
It's working!

I have the superflo vs pump power hooked up to the filter pump relay and the speed one cable hooked up to aux 6. Can I move the speed one cable to the filter pump relay and save aux 6 for something else, or would some power mismatches occur?

Thank you
 
E,

It makes a difference in how you have the SuperFlo VS wired. Is your SuperFlo VS wired to constant AC power or does the AC power come through the pump/filter relay? I "assume" that your Aux 6 and 7 are currently wired to the low voltage control wires going to the pump.

Thanks,

E,

The way it is now your pump should start as soon as the Pump/Filter relay comes on at Speed X. When you turn on Aux 6 the pump should run at speed XX and when you turn on Aux 7 it should run at speed XXX.

If you connect either Aux 6 or 7 to the "Solar booster" relay connection, then that is the speed the pump will run when solar is on.

How would you like to see your system running? Sorry, but I do not fully understand what it is you are trying to do.. :scratch:

Thanks,

I just got the superflo vs automation cable and installed it yesterday, so it's kind of being setup new.

How it used to work is, the filter pump relay would be powered on by a schedule and the pump itself would control the speeds via timer settings on the pump. Speed 1 would run for a preset time, then speed 2, then speed 3.

Now that I have the cable, I want speed 1 to run when the filter pump relay is callled, and I want speed 2 to run when the solar is called. I'll use speed 3 for some other undetermined item.
Yesterday, I connected speed 1 to the aux 6 relay and have a schedule for the pool filter pump to run x time and a different schedule for aux 6 to run at the same time. I have connected aux 7 to the solar booster (j17) so that speed 2 runs when solar is called.

What I want to know is, can i move the low voltage wires from the aux 6 relay to the filter pump relay, thereby saving my aux 6 relay for some other use. I'm guessing no since the filter pump relay wires are high voltage and the digital control wires on aux 6 are low voltage, but thought I would ask.

I hope that makes sense.

Thank you

E,

In "theory" you should not have any low voltage wiring in the High voltage (relay) section of the EasyTouch.

For sure I would not wire the same relay with both High voltage wiring and low voltage wiring.

I suggest that you try this. Set the internal timer for the pump to run 24 hours at speed #1. In theory, if that is all you did, then whenever the pump/filter relay came on, it would start the pump at speed #1. You can then set a schedule in the EasyTouch that actually controls when the pump starts and stops, just by turning the pump/filter relay on or off. Then use Aux 6 to control speed 2, and if you want Aux 7 to control speed 7

You can schedule the Aux relays to come on or turn off when you want. Or you can connect Aux 6 or 7 to the Solar booster port so that it controls the pump speed when solar comes on.

Thanks,

Jim R.
 
E,

Well, maybe something has changed. :scratch:

I suggest that you run a quick test and see how it works..

Have the pump running a normal internal schedule at a low RPM. Not in External only control, and then just turn on Aux 6 or 7 and see what happens.

I could swear that it used to allow the external input to take control and then ramp the speed up to whatever you had set for Aux 6 or 7 inputs. When you turn off the Aux relay the pump should go back to its internal programming.

Thanks,

Jim R.
