Howdy folks, have had our pool for about a month now and learning the ins and outs of the Easy Touch 4 system. I have our VS pump, pool cleaner on Aux 1, Spa Lights/Deck Lights on Aux 2, and Pool Lights on Aux 3. That's all my circuits. However, upon reading the manual, it makes note that if you do not have a solar heating system, that you can use the Solar circuit as an Extra Aux relay. Does anyone know if this is the case and how to do this? I want to take my deck lights off of the Aux 2 circuit and hook them up to this extra relay so that I have true independent control over all of my three lighting circuits. Thanks!
