I am replacing it to get humidity control. Thought I could just pop the unit onto the old back plate, however the old plate has:
Y2 . RC
L . R
E . O/B
AUX . Y
S1 . G
S2 . C
With Black connected to E and White to AUX
New plate has:
Y2 . RC
L . R
AUX /E . O/B
(blank) . Y
S1 . G
S2 . C
The new unit has no E by itself, just one connection labeled AUX/E
How do I connect the Black & White wires? All other wires on right side match up.
