24 VAC to J5-4 closes J11-1 to 2 and is the fan interlock to allow heat to work.
24 VAC to J5-5 does absolutely nothing
24 VAC to J5-6 closes J11-3 to 4
J5-7 connects to J1-1 by a trace in the circuit board
J5-8 connects to J1-3 by a trace in the circuit board
J6 - Some of the wiring diagrams are wrong for J6.
The diagram should be, J6-1 OUT to Unit B, J6-2 OUT to Unit A, J6-3 24 VAC IN.
When 24 VAC is applied to J6-3, the K5 and K7 relay will close outputting 24 volts from J6-1 and 2.
