How to detect power


#1

Now that the Wi-Fi is reestablished my app indicates that the irrigation zones are working. Problem is no water.
How can I determine if the controller (gen2) is actually sending power to the pump?


#2

@GDO - if there is a pump start relay in the system, first check to see that the pump start relay option is enabled under More/Controller Settings/Advanced Wiring (M terminal)/ Well or Pump Start Relay (should have a blue dot). When activating the system you might be able to hear a click when the relay is energized. Or if you have a volt meter you should see 24 volt AC current on the M terminal when checking between the C and M terminals.

Last season the master valve was connected to the M terminal. Just tried selecting the start relay, still no water. Will check voltage in the morning. Thanks.

Checked the voltage on the M terminal (between M and C) and got 0-.4VAC.
Same reading with either Master Valve or Start Relay selected under Advanced Wiring choices.

Does this test the output of the controller to the pump?


#5

Did you get that reading under load or with the wires disconnected?

Thanks for asking but problem solved about four months ago.
