Just installed a Dual Speed pump and looking to take advantage of that feature when I install a digital timer (P1353ME). My question is: how does this work? I can't imagine this timer steps down the voltage. What is the interface that allows the pump to run at low vs high speed?
Interestingly (or maybe not), I was not expecting a toggle switch on the new pump (WhisperFlow WFDS-26) but it showed up with one. Currently hooked up to my old mechanical timer, but the toggle doesn't seem to do anything.
The installation/owners manuals for both are pretty worthless in describing the installation and operation.
Your input much appreciated
