    I moved into a new house earlier this year and the controller is pretty beat. I have never replaced a controller and have a few questions.

    Can I use a different controller instead of Toro?

    How hard is it to do?

    What controller would you go with if I can change to another controller?

    The IC-4... another relic of the early 1980's. LED display. Six keystrokes to activate a zone manually. One of Ed Hunter's last projects at Toro.

    Yes, you can replace with any standard 24 volt controller. I would recommend an ESP series controller from Rain Bird.

    Label your wires (common, 1, 2, 3, 4) before disconnecting from the old clock.

    The ESP will do it.
    Manual operation by individual zones is easier on the Irritrol Rain Dial, but it will cost you more.

    Most reliable controller. Ever.

    And one of the most limited. For instance, waiting for the balance of a half hour to finish before the next zone starts... a three hour watering window... hard when you have 3 of them to water 18 zones for instance... total of 9 hours watering window... :confused:

    At least RCs would advance to the next one and had up to 60 min. per zone.

    First controller i ever played with really. The older style with the fake wood grain decals and logo that looked like orbiting electrons...

    Limited, yes. Most reliable, yes.

    And what other controller features rack-and-pinion operation? :p

    Yeah, and the time dial turns COUNTER-CLOCKWISE, as all good timing devices should.:dizzy:

    I thought the Toro IC series was pretty cool when it first came out. It was not long after we got tons of calls to reprogram or replace them. :hammerhead:
