Safety switch not working on new condensation pump, what wiring do I need to change?
I've got 3 inverters on a split system; basement unit uses a mini pump which I just replaced. When stress testing the new pump, the reservoir filled to the top without the AC shutting off.
The purple and grey wires are from the alarm switch; brown and blue are from the main pump unit; yellow/green is ground (also from main pump unit). The red, white and black wires in terminals 1-3 are from the A/C, I haven’t changed any of those yet.
What do I need to change for the alarm/safety switch to work as expected (i.e. turning off the A/C when the condensate reservoir gets too high)? Or is there some other component that I’m missing?
