Hi,

I keep tripping the house when I wire the astute controller to the geyser circuit breaker. The geyser has a 20A breaker. I take from the load of the breaker to the top of the controller L then a N to the neutral bar. I then take load of geyser into the bottom of the controller, switch power on and it trips. I then went and bought a 30A breaker for the geyser and the same thing happens. I have tested the astute controller by wiring it into the 10A light circuit breaker and it works without tripping. Any advise would be appreciated.

You have wired it to the wrong neutral bar

In other words. You should use the same neutral that fed the geyser before fitting the Astude.
