I have an issue when I hooked up the control box to an old ASP 9000 unit the GFI breaker trips once the toggle switch is turned on. Diagnosing the problem I found that the When I remove the power wire from the electronic thermostat the breaker no longer trips. I did try just disconnecting the load from the thermostat first (i.e. the heating element) and it still tripped. So I am left to believe it is the thermostat as there is nothing else left. I can run the pump successfully without the thermostat but once the power wire is attached to the thermostat it trips. Am I right in my diagnosis that the thermostat is the issue? The thermostat is an ETS1000 electronic thermostat supplied by TecMark. If so do you have replacements in stock? Thank you.
