Even before my Zodiac Z4-PSi arrived, I was looking at the installation manual and scratching my head. Now I am flat out confused!
What I have in boxes in my garage are a Pentair Intelliflo VSP, Zodiac Z4-PSi, and an Aquatherm heater (Aquacal). My first question is, according to the instructions, to wire the pump to the relay on the Z4 controller. Does this mean there is no power to the pump until the relay kicks on? Therefore the pump control panel itself is off? If that is the case, how does the pump know what speed to run at when it kicks on? How does it get its instruction from the controller?
My second question is, unlike the pump, the wiring diagram does not show a heater relay, only Aux 1 (which is shown connected to a blower), Aux 2, and Aux 3. Do I connect the heater to an Aux position on the Z4 controller, or wire the heater directly to the breaker and just use the 'Heater' position shown on the 'Green Terminal Bar' (top center of diagram) and connect it to the Y and Z positions on my heater's control board (Jandy control)?
Thanks for any insight.
