why does it say International use only? Does it work in the USA?
A shopper on May 21, 2013
What do you mean international usse only?
A shopper on Sep 13, 2012
I have a question about this item witch I already have. My sprinkler system is not working and I think my timer is bad it only works when I do it manual do these timers go bad?
Greg W on Jul 30, 2013
BEST ANSWER: I first tried to replace the timer sprocket, still didn't work. I just went ahead and replaced entire unit.
It states that it is 1 zone but we have 3 zones is this what we want?
John K on Apr 12, 2015
BEST ANSWER: I am not sure what you mean by zones. The zones referred to in the product description refer, to the best of my knowledge, to the number of power receivers, motors. The flow valve is what directs the water to different sets of sprinklers. At least that is the way my set up works. I also have three areas or arrangements of sprinklers. Each time the pump comes on the flow valve sends the water to the next area of sprinklers. It stays on that area until the pump goes off. Then the next time it comes on water is directed to the next area, and so on. So, if your application is similar to mine you should be OK. If you have more than one motor or receiver of power, then this timer won't work for you. I hope this helped.
can you use this timer with a 1hp pump?
derek g on Oct 29, 2013
BEST ANSWER: this can be used on any motor less than 2 horsepower ,it has a Dual contact poInt contactor/relay for any single phase 220-230 volt motor, a Lower horsepower motor will actually give this less of a load and it should even last longer
I Have a 5HP pump. Will this work on it? The one I have has been on 30 years and all the numbers are faded off. It looks JIM like this one and it is 220 Volt Thank You JIM
A shopper on Nov 10, 2016
BEST ANSWER: I used mine on a 1.5 horse, but I think the power of the pump would make no difference. As long as it is a 220 volt system. I replaced the old version of this controller on a three zone system and it works fine. You probably have more zones with a pump that big, but the physical switching of the zones is done by the index valve, and the controller just opens and closes the 220 volt circuit to to the pump, allowing the indexing to occur in the time gap you program into the controller between zones. The 220 V ten gauge wiring is hard to work with, I used leads to the posts to make it easier.
Why won't this unit work in the US? I have a 22 year old 220 volt version of this unit I need to replace.
jtmacon on Jan 29, 2014
BEST ANSWER: I don't know why it says that. I installed one last summer and it works just fine here in Florida. It also replaced an old version whose timer motor died.
Are you able to have just one zone turn on continuously?
A shopper on Feb 21, 2019
BEST ANSWER: I use the model 2120 timer that controls pump operation; I intend to run the sprinklers twice a week. The pump is connected to a 6-station/zone selector valve. To cause the pump to operate 6 times in sequence, I insert a cluster of several timing pins tight together into the time dial (2-4 15-minute white pins), one cluster for each station/zone. Leaving an empty space between clusters in the time dial will causes the pump to shut down. When the pump shuts down, the multi-station selector valve cycles to the next station/zone, thus when the pump is restarted by the time dial rotation to the next cluster of timing pins, water is then sent to the next station/zone. And so on, through all of my stations/zones.
The questioner here states he/she has a simple single-zone setup (implying there is no multi-station selector valve between the pump and the single zone). In this instance, simply install a single cluster of timing pins into the time dial, e.g. use 4 pins to run the sprinklers for an hour.
A general precaution regarding the 2120 controller: it operates on a 24-hour time dial clock, with day change occurring at midnight. I choose to run the sprinklers at night, over a span of about 6 hours. The controller will interrupt operation at midnight (shut down), as it cycles to the next day (oops). My simple solution is to treat the time dial as changing to the next "day" at noon, not midnight. Thus, the night operation is not interrupted due to a "day change."
I have a K-2120 it has stopped working because the little motor shorted out, can this motor be replaced or do I have to replace the whole thing?
A shopper on Feb 2, 2015
BEST ANSWER: This motor can be replaced you can get the part # from the owners manual which can be found on the internet. Before replacing the motor make sure you have the proper voltage coming into the motor you are replacing. K rain does have the owners manual online.
Is the 2120 the replacement for the model 1120 and is it the same voltage 220?
david r on Jul 10, 2013
BEST ANSWER: I have the K-Rain "1000/2000 Hydrotek Single Station Controller" manual in front of me. Page 9 of this manual shows both 1000 and 2000 Series Controllers can have either 110VAC or 220 VAC Components - clock motor, relay coil etc. I have used, and still use, the Model 2120 for 220 VAC operation with 2hp pumps. The sticker inside the door shows this to be a 220 VAC unit. In the early days I had to use a different part number for the 220 VAC Controller. Also, there are some pump options that allow you to use either 110 or 220 through the use of a jumper cable connection at the back of the pump. So, for the biggie question - is one model a replacement for the other - probably. BUT! based on the above K-Rain parts listings I would check my old controller to make sure since I do not how old it is. If nothing on the old controller box tells you, remove the two brass screws on either side of the large Time Dial, pull out the electronics, and look at the back of the unit for relay coil or timer voltage labels. You can look at your pump to see if it requires 110 or 220. And, if all else fails, just measure the voltages with a meter. Another interesting thing I found on the Sprinkler Warehouse internet site was the words "for international use only" in the description for the Model 2120. I do not know if it was Code, Lawyers, Manufacture/Seller issues, or politics that forced this statement, but 220 VAC 60 cycles is the same here and at Timbuktu. I have used the Model 2120 for years without any problems. Be careful working on electrically connected equipment. Best Wishes.
I have figured out how to use this product manually. But I cannot seem to get the timer to work properly. any tips?
A shopper on Mar 30, 2013
BEST ANSWER: To make the timer work automatically, the switch has to be turned upward into the " Auto " position. Then, as the timer wheel is turning, you have your pins inserted into the correct hourly holes so that the pump will turn on as the timer wheel pin "runs" over the switch that you turned into the ' Auto " position. Each pin inserted is 15 minutes on, so if you want the pump to run 30 minutes for that section of lawn to be watered, 2 pins would be next to each other, 3 pins for 45 minutes ...etc. Leave an empty space between each set of pins for each different section of lawn watered. Now, if the timer wheel isn't turning, then the small metal motor is bad, and will need to be replaced. It is easy to do, just pay attention to how you dis-assemble it.
Do yuou have the same model in 110 Vol. to use in USA? can I water 5 stations with it?
Thank you for your answer.
Mario D on Jul 30, 2012
BEST ANSWER: The 2120 controller is an international model rated at 220 volts. I replaced one for a neighbor because of his familiarity with this model. You can water 5 stations if you have that many zone pins and if you have a multi-port valve with 6 outlets. One of the zone pipes will be capped if you have 5 zones.
I have a problem with the unit causing the breaker to trip in the breaker box. I can manually override it, but I want it to work automatically. Is it a grounding problem?
Robert D on Jun 11, 2018
BEST ANSWER: Is your unit on a separate breaker? I know that mine is and that may be what's causing your problem by overloading the main breaker panel for the house. As far as grounding goes, if you don't have it grounded that also may be a problem.
is K-rain model
2120 the same as Hydrotek model 2120?
A shopper on Apr 26, 2015
BEST ANSWER: Yes the exact same thing, different housing box is only difference. It works great.
I just moved to a house that has the 2120 K. How do I get it to change zones on manual or does it change after a period of time? I just fertilized my yard and want to soak it

Just installed a brand new unit and it will not work manually. Does it have to run a complete cycle first? It is receiving power but just won't click on!
