Description

Upgrade your irrigation system with the Hunter Wireless Solar Sync® Sensor, a weather-responsive sensor that automatically adjusts watering times based on conditions at your property. The Hunter Wireless Solar Sync® automatically adjusts irrigation run times based on local weather conditions and works with compatible Hunter controllers including X-Core®, Pro-C, ICC2, I-Core, ACC, ACC2 and MCC. Solar Sync® measures sunlight and air temperature to calculate local evapotranspiration (ET), then adjusts compatible Hunter controller run times to help your landscape receive the right amount of water as weather changes. Built-in rain and freeze sensing can also stop irrigation during wet conditions or when temperatures reach 37°F. The wireless design simplifies installation without running sensor wire back to the controller, while an integrated battery provides maintenance-free operation. It is ideal for homeowners who want smarter irrigation, improved plant health and less unnecessary watering without replacing their compatible Hunter controller.

Dependable 10-year sensor for Hunter X-core controllers

I purchased a WSSSEN for my Hunter X-core controller from the Sprinkler Supply Store 10 years ago. The sensor worked well during its entire 10-year lifetime. The sensor is supposed to be replaced every 10 years, so I purchased an identical sensor through Amazon. Amazon offered the best price and a trusted distributor (Sprinkler Supply Store). I have installed the new sensor, and everything is working well. I am expecting to have 10 more years of good service from this new sensor.

Great price! The hook up is easy and works fine so far.

Works perfectly.

Bought this kit to replace the original receiver and transmitter. Installation of both items was easy since they were replacing originals. Syncing of the 2 was seamless. The real test would be when we had our first rain, and that came a couple of weeks later. Worked as it should have.

All items pictured not included in shipment received.

It didn't matter in my case because it was a replacement part, but be advised that all items pictured (extender and mount) were not included in the package.

Saves water, saves money.

Installed into my existing Hunter irrigation controller. I have it a few months now and I see a real big difference in my water bills. works very well, and was easy to install.

A good addition to my sprinkler controller system.

Seems to work well. It definitely changes the setting on my sprinkler controller. Will know better about its performance once I get an entire season of experience with it. My yard maintenance guy is a bit sceptical about it, but so far has taken a wait and see approach.

Nice tool.

I was skeptical of this but after installing it, pretty nice. Works like it’s supposed to and I don’t worry about over or under watering. Takes a little bit of time to calibrate it for your own scenario but very easy.

Easy to install. Would give it 5 stars but am still monitoring its operation. Seems to be working as described, so, far.

This was easy to install into my existing Hunter irrigation controller. It has been in operation for nearly a month and has performed flawlessly.

Research YouTube prior to setting up if you are weekend dyi type.

Impressed with ease of installation (used guidance ) from YouTube. Have been very satisfied with working properly especially since we had several rainy days this past month in which the system would turn off and on automatically depending on outside conditions. Was especially happy since this was purchased at a much lower price due to previously opened box.

I'm going to give this 4 stars seems I only had it installed for a month or so. So far it has worked very well. I had the wired model and went through 2 sensors before a full refund. Wireless is definitely the way to go and worth the extra couple bucks.

Well Worth It

Now after having this product a few months in happy to report it works Great! It has saved me not only money but the hassle of hav8to worry if I've watered too much or too little. I mounted to a tree about 150 ft or so from the receiver and have had no issues. Worth the cost. Highly recommended!

Electronic control of sprinkler timing

Great effective water conservation add-on. It will set back the set times for each station depending on recent moisture and temperature conditions. For instance a week after we received 6" of rain, the controller indicated that the sprinkler times would run at 56% of the settings. During that week we had warm dry days and the soil was dry near the surface. Of course after a rain, the Solar Sync will prevent watering until the controller senses that evaporation has occurred. We received 50% rebate for the cost of the Solar Syncs from the City for adding the devices to our 5 , I-Core controllers.

I think there are better options out there

After using the builder supplied Hunter I-core system and the Solar Sync add-on a couple months now, I think there are better options out there.This feels like 1990s software. Time to re-engineer Hunter.

A quick and easy install is all it takes to save water.

Receiver unit installed into my Hunter Sprinkler XC600i X-Core 6-Station Indoor Controller Timer 6 Zone with no problems. Just two wires to connect with a screwdriver.Transmitter was easy to install off of a rain gutter.NOTE: Install the Receiver FIRST, then check/verify the pairing before climbing up on a ladder and installing the transmitter.

Excellent Addition

Easy to install and works as expected. Excellent addition to postpone watering when it rains.

A must-have for every irrigation system

I think this is worth paying a little more than the freeze-clik. The wireless sensor is a good option to minimize wiring, and can easily be brought inside when the system is winterized to protect it. This will pay for itself with just a few water bills/saves a lot of water and was very easy to install after viewing videos on the Hunter Industries website. I see irrigation running when it rains and during freezing and this will prevent it. The seasonal adjustment was a little tricky - make sure you locate your sensor in the sunniest part of your lawn for it to work properly. If you locate it in a shady area it drops the seasonal adjustment too low, meaning not enough water for your lawn/plants.

Correctly adjusts irrigation in Phoenix area

I have the Solar Sync connected wirelessly at a distance of about 30' to a Hunter Sprinkler XC600i X-Core 6-Station Indoor Controller Timer 6 Zone. I adjusted the Solar Sync Setting to 4 5 for the Phoenix, AZ extreme heat and low humidity. That gives an a summer seasonal adjustment of 80-90%. The max temperature has been about 115F. The few times it rained the irrigation was shut off correctly for a day. I recommended to my landscape architect that he quote this unit with every job that uses an XC600i.Update: 5 months later the unit is still working fine and the winter seasonal adjustment runs between 20 and 30%.

Frequently Asked Questions

What does the Hunter Wireless Solar Sync Sensor do?
The Wireless Solar Sync automatically adjusts irrigation run times based on local sunlight and temperature conditions. It also detects rain and freezing temperatures to help prevent unnecessary watering.
How does Wireless Solar Sync adjust my watering schedule?
The sensor measures solar radiation and temperature to calculate local evapotranspiration, or ET. Your compatible Hunter controller uses this information to automatically adjust programmed watering times as weather conditions change.
Does the Wireless Solar Sync have freeze protection?
Yes. The sensor prevents automatic irrigation when temperatures reach approximately 37°F to help avoid watering during freezing conditions.
Does the Wireless Solar Sync require Wi-Fi?
No. The sensor communicates directly with its wireless receiver and does not require a home Wi-Fi network or internet connection.
