Re: AutoPilot Pool Pilot Digital RC-42 out for delivery...
OK - Here we go!
Here's the existing cell:
...and the existing controls:
Let see what's going on with the existing wiring:
(Note - I am experienced with electrical repair. I left the power on if needed to determine the circuits. As I suspected, residential pool wiring, no diagrams.... Better to track a circuit by voltage than by continuity with power off. As soon as I figured out the existing circuits I disconnected power to all the pool equipment at the sub panel.)
Best possible scenario, relay for the pump is internal in the existing SWG as the Pool Pilot will be. O2 light is wired parallel off the motor relay. Wiring will be very straight forward.
I decided to install the control unit first as the weather looks threatening. Would like to get the electrical done before everything gets muddy and wet, and early in the day before it gets too hot. I think I'd rather deal with gluing PVC than wiring in the mud and the heat!
All wires labeled.
Old control box hangs on a section of super strut by a lip. New box has hang holes so here goes another trip to Home Depot, for some spring nuts. Also, note the large bolt head on the QuikChlor box... I know what that is! (pics later)
OK, back from the store with the proper hardware...
Pool Pilot mounted, starting to rain, better put the cover on!
Here's what I knew was inside, a HUGE toroidal transformer!
Output is 9.2 amps @ 28VDC, DIG-220 output is 8 amps at an unpublished DC voltage. Transformer is much lighter and smaller. Eek! Hope this is because newer technology is more efficient and needs less power...
Way less electronic circuitry inside the QuikChlor:
Hey! Rain stopped, going to go finish the wiring and cut some PVC....
