Do you need to purchase two sensors to replace water and air sensors? Do I really need a water sensor if I don't have a heater or only air sensor?

You do not need to purchase two. If your system only has one sensor that's all you need. In my case, the water sensor failed and this item replaced it perfectly. My system's original air sensor is still working fine and I expect it will for a long time as it is sheltered from the elements.

I don't know your setup as I used it to replace a bad one. It did the job, but didn't fit like original.

To monitor air and water would require two of these sensors. The air sensor is normally used to trigger the freeze protection mode. If you don't have a spa/pool heater then I would not see a need for the water sensor.

The unit is designed to monitor temperature, power, and water. It is not designed to incorporate other sensors. There is only one water sensor included and one input in the controller for the water sensor. I don't know if you could tie additional ones into the line for the control unit. The unit is designed for use in one building although you could conceivably locate the water sensor in one area (within 100' of the control unit), a basement for instance, and install the control unit in a garage to monitor the temperature simultaneously.

One sensor... remember you need two if you want to monitor the standard set of tires on a motorcycle. :)

Hello. It comes with one sensor (water) but can also work with several others (I use a temperature sensor with the SK642. I purchased the Ideal products through Amazon. VERY pleased with the dialer & both sensors.

The same sensor that I received has only two wires. READ CAREFULLY THE INSTALLATION INTRUCTIONS AND Y you will be on your way. Enjoy!

First of all you don't have to activate this sensors. Wires from thermostat should have connection to this sensors. You connect the sensors first and then thermostat. Hope this helps. Let me know if you have question.

I believe it did I purchased a second sensor and installed both of them so if the first senor failes I can hook up the 8ther sensor.

HiIf you already bought one of the iSmartAlarm packages the next step is to configure the system. All the necessary is included.If you only bought the sensor it is mandatory to acquire at least the prefe

You are better off replacing both and this kit will do it. I had the same issue in which I only needed one. But you are hard pressed to find just one sensor that will work. Save yourself the headache and use a kit.

Nope. The sensors and switches are all built in.Very easy to install the unit. Pick up some weather calking before installing unit. Takes 10 minutes to install.

The one I purchased came with two sensors. And they work WONDERFULLY!!! I bought two more, and added them. These little detectors are great. They are sensitive, too (placement is key).

No. I had to replace my sensor awhile back because I was getting hot water through the cold water tap. You need the sensor valve for it to work correctly.

Comes with 2 sensors. Just need a dry pair of underwear not new sensor as it does not stay wet.

Yes John, this includes the flow sensor. A very complete kit with great instructions; took a couple of hours for install and once running, it made a world of difference in pool water quality. Ran the last half of the summer by adding 4 more bags of salt... that's it! Water was clear and algae free right to closing in mid-Sept. Looking forward to my opening in 7 months!

No sensor included. If you do your own brakes, just monitor how much pad you have left and change it before the sensor gets tripped if you want to save a few extra bucks. MB sensors are not too expensive. BMW ones have a long wire attached and it runs like $30 to replace, ouch!

Same sensor. More about what you can afford. If you can spend $300 more dollars I would!
