Hope this topic finds you all great, here is my problem and hopefully, someone can help me:
TLDR; My setup is the controller (Rachio Gen 3) connected to an Orbit 1-2 HP Pump Start Relay (Master and Common wires) and everything seems to be working as the well pump starts as expected when I try a quick run. The problem is that even when the countdown is over the pump doesn’t stop (cause the relay doesn’t switch to off).
That is the short version, now the discoveries: Experimenting with a multimeter I found out that when the controller is not connected to the relay (thru the 24 vac wires) it effectively stops sending 24 volts once the quick run stops (countdown reaches zero). However, when it is connected to the relay - and using the multimeter - once the countdown reaches zero the voltage on the wires is still 24 volts, explaining why the relay never switches to off. Then of course only turning the controller off or pulling the cable from the relay, switches the relay to off stopping the well pump.
Any idea what can be happening here?
Thanks in advance.
Note: The controller is more than 15 feet away from the relay.
