I have 4 valves: The first 3 need to activate a pump to draw water from a well. The 4th valve doesn’t need to activate the pump because it draws water from the municipal water system. How can I connect and configure my Inkbird to work like this?

You could do this by using a relay between the Inkbird Master Valve output and the relay that turns on the pump. This would be Normally Closed and you could connect the coil of the relay to the output of zone 4. One wire going to the relay and another to the valve. So when the valve is ON the relay will open which will disconnect signal to the Pump Relay.

Thank you Φοίβο!
Sorry for the long delay in responding. Unforeseen circumstances kept me from installing my Inkbird until today. The old system is out, Inkbird is in and working just fine. It was all very easy to do and the app worked without a hitch.
Not being an electrician myself, I’ll need expert help to look into implementing your suggestion. And I’ll let you know how it goes!
