Hi, I recently tried to replaced my mothers timer on her underground
sprinkler system. For some reason its not working. The zones don't recognize
the new clock. The new clock is 24volt. I think that is where the problem
is. Her system is about 30 years old. Did they use a different voltage in
the past? Steven
Sort've doubt the voltage has changed much. The solenoids on the valves might
require more current than your present timer / wall wart is capable of
supplying. I'd try simplifying the problem, and just try jumpering the wall
wart directly to one of the valves to see if it actuates. Oh, and to cover the
obvious -- make sure that the water is actually turned on to the system -- if
the system had been winterized, the water is probably still shut off.
I just recently went through the same thing at my mom's house.
I replaced an older sprinkler timer with a Toro 8 station timer.
The sprinkler valves & solinoids are ~30 years old .
(I installed them personally when I was a kid)
They work fine with the new controller. When you say they "don't
work", do you mean in manual mode or in sutomatic mode?
The Toro unit requires that you press the manual start button twice to
Solinoids are pretty much unchanged for the past 30 years or so.
All the systems (5 total) I have installed or repaired in the last 30
years work fine with the currently avavilable Toro timer.
what brand is the new one?
I suggest getting a Toro
I use them in all my installations, at my houses & my mom's house.
24v solinoids have been pretty munch standard for ~30years all modern
timers should work fine.
