I was able to get the heater to turn on/off via the outside panel (didn't have access to the inside panel) by:
1) At the outside panel, turning the filter on and putting it into "Spa" mode.
2) Once that was done, manually turning on the heater by hitting the "Spa" button on the heater's panel.
3) Then, when I hit the "Heater" button on the outside panel, it would turn on/off as expected.
4) I then only turned off the heater and filter from the outside panel.
5) I was then able to control the heater from the outside panel whenever I turned on the filter (in other words, it worked as expected)
My questions are:
-Is leaving it this way normal or a problem? I ask because when I turn the filter on, the heater's panel shows a green light for the spa, and the "pressure switch" led blinks red.
-I'm also not sure what happens if I would try to heat the pool (since its LED isn't light at the heater panel). Maybe in my setup it doesn't matter?
I'm attempting to attach pictures to this post as well.
