I am having issues wiring up a new Panasonic FV-0511VHL1. I removed an old vent/heat/light combo unit controlled by 3 single-pull switches. For me, the wiring diagram directions are confusing and do not match my current switch layout. Does anyone have any experience with this? I have attached images of the old junction at the unit and images of the new. I know the ground wires go together, the white wires go together, and blue wires for the light go together. I do not need the night light function. It gets confusing on how to hook up the fan and heater. Any advice?
