Easytouch no longer controlling Intelliflo

Hello all, I have an easytouch 4 controlling my Intelliflo VS Pump. Everything has worked fine since installation. Recently Intelliflo stopped running its’ easytouch schedule and cannot be run manually either. Display correctly shows Display Not Active so there is some communication between easytouch and pump.

I contacted Pentair and they advised that it was either the connecting cable, Intelliflo drive or easytouch motherboard. First, I replaced the cable with no change. Now I have disconnected the cable and am running the Intelliflo on a program and it is working fine. Before I replace the motherboard, is there a way to test it, i.e. moving my spa pump over to F1 to see if it works?

ft,

If the pump says "Display Not Active" that "should" mean the mother board is OK.. Otherwise the pump would just show the standalone pump pages.

Show me the following set up page...


If your ScreenLogic works, the mother board has to be good.

I don't know what F1 is, but if your IntelliFlo is wired through the Pump/Filter relay, it is wired wrong.

Thanks,

Jim R.

ft,

Rats... I was hoping that the speeds had been erased.. If you change the pump type it will often erase all the speeds, but that is not the case..

Have you recently been adding any new schedules?

What does the "Delays and Alerts" page say?

The IntelliFlo is controlled by the cable and not the pump/filter relay, but the two do work at the same time.. It would be interesting to know if the pump/filter relay closed when it should, but the pump did not run.

When you schedule something like your spa or spillway, do the valves turn like they should, but the pump just does not run?

Thanks,

Jim R.

Hi Jim, no new schedules.

Delays and Alerts page shows
Pump 1: Communications Lost. That may have occurred when I disconnected the cable so I could run the Intelliflo on its’ own program.

I hooked the cable from easytouch to the Intelliflo and started the spa mode. The valves turned as appropriate and the heater light turned on, but no pump.

I am not sure where to go from here.. If this were my pool, I'd want to know if the IntelliTouch scheduling was trying to turn the pump on or not.. In theory, if the pump's display say "Display not active" that means the ET is controlling the pump.. For the pump to start, a schedule has to do two thing.. Send a RS-485 command to the pump over the cable to run and it will also close the Pump/Filter relay and the little light above the "F" button should come on.. I'd watch the light above the "F" button and see if it comes on when the schedule says to start the pump. If it does, it means the scheduling system is working.

Unfortunately, it does not really tell you if it is for sure the pump's control panel or the board in your Intellitouch..

Let's see if Tom has any ideas on how to isolate the problem... Calling @ogdento

Before you buy a new board, I suggest that you PM Tom..

Thanks,

Jim R.

Hmmm, as I was reading all of this I had "check pump address"... and then I saw Marty's reply saying it! The intellitouch allegedly always sees a single pump as pump #1, but I'm not sure about the easytouch - I don't know if it has to be set at the outdoor panel as well as the pump.

It sounds like your outdoor board's comm circuitry might be working, but to be sure I want to know if you can control anything using screenlogic... you said you started spa mode and the valves turned, but did you start it using screenlogic or from the easytouch outdoor panel? if it was screenlogic, we can say for certain your Easytouch comms are good

ok, that's great... so the communication circuitry on the outdoor board is working. Pentair equipment uses rs485, and each device (pump, screenlogic, outdoor board, wireless remote, etc) has it's own communication driver connecting it to the rs485 comm-bus (aka comm port).

I'd shut everything off (pump, easytouch, screenlogic - you don't want power on the red/black wires on the comm port), and then do the following tests:
- test continuity of the two wires (green/yellow) on your pump cable
- connect ONLY the pump to the comm port on the outdoor board, then power the system back on. See if you still get "display not active" and whether the outdoor board can control anything.

btw, your signature still has intellitouch in it... do you have anything else connected to the comm port besides the pump and screenlogic?
