Not sure if anyone else has, or has had this problem with the Zodiac Z4.

If I set my pool pump program from say 8am - 6pm, but at 5:30pm I manually turn on the spa mode, at 6pm the spa and heater shuts off, the valves move to the pool setting and then nothing happens. I then have to manually switch the spa mode back on. Why is the manual spa mode not overriding the pool mode shutting off? Maybe a factory reset? I have tried a couple of times to 'clear memory,' but it does not help.

Any thoughts? Thanks.
