Hello and thanks in advance

I recieved the Dig220 & sc60 unit today -- wow it's alot bigger / heavier than I thought. I was surprised that the bottom of the unit was open and not enclosed.

I have a couple questions:
Can you install the controller on vinyl siding (on the house) or do I have to cut out the vinyl siding or should I build a flat surface on a post? I don't think the wire to the cell would be long enough for me to mount inside.

Electricity -- do you use conduit to connect to the bottom electrical or do I need weather proof connectors? Where the wires come out confused me - I'm used to knock outs.

Is the directions for the wiring of the pump to run under the autopilot timer under "Connecting Pool Pilot to One-Speed Pump" on page 5/6 of the manual? Also my pump is a single speed (without a timer) on a 110 volt line. Should I wire the autopilot to 220 v or 110 v to run the pump?( I have a 220 line ther as well). Do I need to do anything with the existing switch - or just ensure it remains on?

On the cell -- I have 1.5 piping -- should I just use a 2 x 1.5 converter? Should I add quick connects union on each side?

Thanks again
