This series replaces our popular ET100 series.

Multi-volt operation from 120-277 VAC, 50/60 Hz.

Review: Works great for my 3/4hp pool pump - I installed this in my pool shed for the 3/4hp 220v pool pump. It works as it should and is very easy to program. I wanted something very basic to just turn the pump on and off at set times during the day and this fits the bill perfectly. I am very happy with it so far. Two things to note, this is not in a weatherproof enclosure so it needs to be installed inside, out of the weather. The other thing is if you do not have an advanced understanding of home electrical you may want to have a professional install this for you.
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.

### ⭐⭐⭐⭐⭐ No More Mechanical Timer Motor Burnouts
*by G***O on October 13, 2023*

Here in the Miami heat and humidity, my mechanical T104 Intermatic timers would cease to work because the little motor inside would fail. After replacing that little internal timer motor 5 or 6 times (about every other year) for $40 a pop, I decided I had enough and ordered this digital version. It was a perfect fit in the existing Intermatic box. I was a bit confused with how to properly wire it, but a call to Intermatic support gave me the information I needed to properly connect it. Honestly, I was extremely impressed with Intermatic support! They were friendly and efficient. I would go as far as to say that EVERY company providing customer support should model theirs after Intermatic. I intend to buy another one of these for my sprinkler timer when that old one fails.
