I have this timer and know I don't need the High/Low speed timer feature since the Dig220 does this but I would like to use the On/Off feature. The wiring diagrams are somewhat vague in the Pool Pilot manual and since my Whisperflo is two speed I am trying to determine how exactly to wire this from the Pool Pilot. Any suggestions would be welcome! I have had several electricians look at this and they all say the timer wiring diagram in the Pool Pilot manual can't work when it is wired up for a two speed pump unless it is set to only turn it off and on when it is on either high or low but not both.
