Re: single zone sprinkler timer question/help

According to kyle <cartesiankyle@xxxxxxxxx>:
I need a SINGLE ZONE OUTDOOR timer (it's on a 20amp 110v breaker).
Can anyone be so kind as to link me to something that will work for
me? Also, excuse the ignorance if a 4 zone outdoor timer will work, I
just couldn't find that answer out.. the people at home depot weren't
as helpful as they usually were (maybe it was a busy Sunday).

"Normal" multi-zone sprinkler systems with sprinkler pumps
usually work like this:

1) high voltage relay to turn on pump while the zones operate
2) low voltage (usually 24V) to control electric valves for each zone.

However, since you only have one zone, no valves, and just the pump,
you can get away with a simple 120V timer and have it simply
turn the pump on and off.

For all intents and purposes, this is exactly the same as controlling
a pool pump.

The Intermatics that someone else pointed you at will do the job well.
I have one controlling our pool pump.

However, unless the unit is specifically rated "outdoor", these should
really be installed in a protected location, preferably inside the house.
[Mine is inside the house which is a bit of a PITA if I want to turn
on the pump outside of the timer.]

If the pump has a 3 prong plug cord (instead of direct wiring) you could
also use a regular three prong electrical utility timer, provided that
it's rated for the motor and suitable for the location you want to put
it in. It should be considerably cheaper than the Intermatics.
