Review: Replaced Mechanical Timers - I had 2 Intermatic mechanical timers in a T30404r outdoor box for 20 years this year to control my pools main pump and pool sweep/heater. I've moved the box several times now due to some remodeling. The last time I moved it, the wall I placed it on hums and can be heard just loud enough to be heard at night while I try to sleep. If not for the humming, I expect the timers would probably last another 10 years if not more. I ordered a ET1125c electronic timer which arrived in a few days. It was shipped from JD's Electrical Supplies. It was in new packaging as I would have expected. However I quickly released that I would need a second timer after all. I hit the "Buy Again" button and a few days later, I get what was obviously a returned unit. This one came from PLEXSUPPLY. While the unit itself still looked new, only one of the 3 installation sheets was in the box. There were 3 installation sheets in the first box, one in English, one in Spanish and one in French. The sheet that came with the box from PLEXSUPPLY was not in English. Without the English version, I would have sent back the unit from PLEXSUPPLY. But since I had the one that came with the first unit, I kept this used unit. Additionally, the second unit's plastic safety apron that covers the contacts after install barely stays on the timer due to rough handling. The unit was preprogrammed already which I had to clear and the voltage switch on the back was not set to the defaults as listed in the install sheet. I was pretty sure I would be returning this second unit expecting it would not behave as expected. I was very happy to find that the new electronic units snapped right into the T30404r box once I removed the mechanical units. I made some jumpers as listed in the install sheet, wired up the rest of the wiring, programmed on and off events and I was done. No more humming. I needed two 240v setups, one for each pump. Thanks to Intermatic for making high quality, long lasting products. The install was easy with the very detailed install sheet. Hopefully the return unit I received will not be an issue. Otherwise I'll be reaching out to PLEXSUPPLY.

### ⭐⭐⭐⭐⭐ Works as advertised
*by M***K on April 1, 2019*

I bought this timer for use with new landscape lighting. The landscape installer supplied a photoelectric control, which is nice if you want to turn the lights on @ sunset & turn them off @ dawn. Since there are quite a few exterior lights installed, I didn't want them all on all night. So, in installed this timer in-line with the power to the photoelectric control & lights. Now I turn on the power @ 5:00PM, if it is still light outside nothing happens. When it gets dark the lights turn on as expected. I turn them off @ 11:30PM. I also turn them on @ 5:00AM, which is when I usually leave for swimming. Programming is straight forward, the manual override is easy to do & this model has a second circuit, which I'm not using right now.
