How to hook a water hose to a water timer to an A/C unit to turn water on/off when a/c goes on/off, respectively.
Requesting information on how one would go about programming a gadget such as an electronic water timer (such as a GroundWork Automatic Water Timer) hooked up to a hose and also hooked up to my Central air unit wiring outside.
Specifically, I would like to have the Water Timer be "triggered" to come on when the A/C unit kicks on. I want to do an experiment which would require spraying water on a portion of my roof for temperature measurements, but I only want the hose to be spraying when the A/C unit comes on and stop spraying when the a/c shuts off.
I would be greatly appreciative for any direction or guidance.
