Unfortunately someone went to great lengths to copy/paste the wrong instruction guide to this solution. Like me, the OP has a 3 outlet PHOTOCELL timer, not a 2 outlet DIGITAL timer. Photocell determines dusk/daylight/etc. We also have the same issue. Wondering if has to be connected directly to outlet. Ours worked fine when plugged into outlet. When we moved it after Xmas to run year-round lights, plugged into extension cord and problems began. No response to date on emails sent to mfg.
