Just purchased your OS3.0 AC. My setup has has my Pump in a below ground pump house with drain. The pump house also has a separate pond pump which will be controlled by the OS3 as a zone. I made a overflow float shut off switch that is similar to the attachment and has 2 shutoff limit switches. I could attach the switch to shut off one phase of the 240vac pump and the other switch to shut off the 120vac pond pump in the event of an overflow/leak.
My question is, could I attach a “dummy zone” wire instead that would shut off the relay to the pump, and send me a notification of the error?
Thank You, Bill
Attachments:
One option is: you can connect this switch to the sensor port as if it’s a rain sensor, so that when it’s activated it will stop the watering programs, and you can configure IFTTT notifications to send notification on ‘rain sensor’ events.
Sounds good! A couple of questions:
1: Is this still true (firmware only supports the first sensor SN1 currently)?
2: I am limited on my in ground wires, can I use the common for one of the wires?
3: If I can use the common for one wire what would be best NC/NO. NC would seem best, with NO you wouldn’t get a failure notice if the wire or switch failed.I just installed my OS.3.0 today. Worked perfect the first time!
4: Looking at your 16 Zone expander- is it similar in size to the OS.3.0? Limited space in my control box.Thank You for a Great product!, Bill
1: Is this still true (firmware only supports the first sensor SN1 currently)?
With the current firmware (2.1.8) yes, but there is already a pull request in github to enable the second sensor, so we will look into that soon and should be able to get SN2 enabled soon.
2: I am limited on my in ground wires, can I use the common for one of the wires?
NO, you should NOT use common wire — common (COM) and GND are different on OpenSprinkler. If you have a switch-type sensor, it should be connected between SN1 and GND. Do NOT plug it into COM.
3: If I can use the common for one wire what would be best NC/NO. NC would seem best, with NO you wouldn’t get a failure notice if the wire or switch failed.
As I said, you cannot use common wire for sensor.
I just installed my OS.3.0 today. Worked perfect the first time!
4: Looking at your 16 Zone expander- is it similar in size to the OS.3.0? Limited space in my control box.Zone expander is about the same size as main controller, but shorter in depth. You can find out the size by going to the product page, and click the ‘Additional Information’ tab.
