Answer: 
The only difference that I can tell is the instruction sheet has been rewritten, with more emphasis on the instructions.

Answer: 
I believe the only difference is the t104r has only one "on and off" and the t104r3 has multiple "on/off" settings. To be sure, go to Intermatic Timers web site to confirm

The T104R is in a gray painted enclosure, the T104R3 is in a beige painted enclosure. Otherwise they are identical in function.

Answer: 
Yes, timer is easily removed and was re-installed without any modifications to fit perfect inside my existing box. Very simple for any DIY'er, just make sure you take pic of the wiring before you remove the wires from terminals of course, MAKE SURE POWER IS OFF!

I just purchased a new TIMER to replace a 14 year old timer that the clock stopped working. The new one, (the clock) is working but it is running

runs fast, two hours in one day. You can imagine how this will wreck havoc with my schedule of watering. IS THERE (LIKE EVERY CLOCK HAS) A SREW OR SOMETHING TO ADJUST THE CLOCK RUNNING FAST OR SLOW FOR THAT MATTER?
WILL I HAVE TO HAVE IT REMOVED AND REPLACED WITH ANOTHER COMPLETE TIMER? The expense of doing that is so high.

Answer: 
If its a 24 hour clock, it should run like a normal clock. If it isn't then it may be broken. You may have to return it.

Rated 4.6 out of 5 by 25 reviewers.
Rated 5.0 out of 5.0 by Intermatic Performance It took 45 minutes to throw circuit breakers off, take off old swimming pool pump, put on Intermatic T100, wire the Intermatic 240 volt/40 amp, program the automatic on/off function, flip the circuit breakers back on, and use the manual override to test the new switch. Perfect, and has continued to be so. October 18, 2016
Rated 4.0 out of 5.0 by now the lesser of 2 I have been around this product now for 50 years due to I am a electrical contractor and my dad was and my grandfather was so I have seen this company change hands and now they have closed production in the u.s.a. and moved to mexico, a few years ago they had American flag on everyone with made in the u.s.a. I noticed it gone but not a mexico flag so they must not be proud of coming from mexico. August 30, 2016
Rated 5.0 out of 5.0 by Perfect Replacement I bought this timer as a replacement to run my pool filter pump (the old one was broken, and the company who made no longer is in business for a replacement timer mechanism). The box mounted in it's place perfectly, and was a breeze to install and wire in. To top it all off, this unit was very inexpensive vs going to a pool supply house for the same type of replacement. I'm very pleased. August 3, 2016
Rated 5.0 out of 5.0 by Worked great Worked great. I ordered online and picked up at store, saved me a lot of time. June 28, 2016
Rated 5.0 out of 5.0 by The Gold Standard for Timers This time switch was purchased for use with pool equipment and replaced an earlier model with a plastic case. The new weatherproof enclosure is vastly superior to the older model which eventually suffered from weather exposure, became brittle and broke. This is a great example of product improvement. They left what worked well alone and only changed what needed to be improved. May 24, 2016
Rated 5.0 out of 5.0 by Very Dependable and Simple The time clock enclosure is well built and outdoor rated. The manual override switch makes testing connected equipment easy. The on/off settings are easy to install and adjust. A great alternative to buying a digital time clock. January 5, 2016
Rated 5.0 out of 5.0 by excellent timer, great price Needed a 220 timer for my pool pump. Found some online but was pleased to see Home Depot had the same price (or less) and it was in stock at my local store. Thanks for the help September 15, 2015
Rated 4.0 out of 5.0 by Reliable AC timer The installation instructions were clear and easy to follow. The unit performs as described and is very reliable. September 8, 2015
