Is it really necessary to run 4 wires with the
corresponding 4 relays?  Is this just to prevent
losses by halving the current through any one wire, or
for redundancy, or something else my electrically
feeble mind can't follow...

My relay job just used 2 wires and two SPDT relays to
control both high and low.  I'm happy with the
results, just wondering why the guru suggested what he
did...

Thanks,
