Thanks for the response. I now had a new borehole controller installed on which the overcurrent protection is active, and the controller does not show any overload, and also nothing in the logs.
Everything is exactly the same, however; the stations show being activated, but the station allocated to the pump goes red after a short while, and the borehole controller shows no activity. After waiting about 10-15 minute, the pump station suddenly activates, together with the other sprinklers.
Please assist wih how I may debug this further. I’ve got a 90% running system; it’s now only the pump start issue that remains.
Kind regards,
Charl
