Irritrol Rd600-ext-r Review

I purchased this unit as a replacement for the prior generation of the same unit. If I had wanted to, I could have simply swapped out the control unit by detatching the ribbon cable and popping the old one off its hinges. However, I removed the entire old one and put this one in its place. I did not install the original unit, but the whole replacement process took around 30 minutes.

This new unit has a nice feature that allows it to be programmed "offline" by using power from the 9-volt backup battery. That's nice so that you don't need to stand at the terminal (outside, in the sun... it's over 100 degrees here) to perform the setup.

The unit is simple to configure and use and the manual is easy to understand, even if you have never seen this kind of unit before.

For those interested, the prior version (8+ years old) has a known bug in the code that causes it to "freak out" periodically and stop activating its stations. The temporary fix is to kill all power, remove the battery, wait a few minutes, then re-apply power. Usually, I needed to reprogram the thing after that little exercise. That works, but is inconvenient and you usually only find out it has happened when your plants start to turn brown.

This new version has NVRAM that stores your programming even if the backup battery dies -- oh, and the bug is supposed to be fixed. So far, so good.
