I tried also to connect the waterpump to "NC" and, actually, I can solve the resetting problem. However, after that few seconds of reset the pump stays ON forever until I give the command to close the waterpump. So, I thought that what I need is the NO state.
What do you mean that my connections/wiring are not fine? If you mean in terms of esthetics I agree with you, but it was a fast example to show you. If you mean that I did some mistakes, please tell me.
Thanks
