6. PURPLE WIRE CONNECTS TO TRANSFORMER
(PIN 1).

8. TO RUN DIFFERENT SPEED FOR HEATING AND
COOLING, DISCONNECT GEEEN JUMPER FROM
"COOL" TERMINAL AND REPLACE WITH
APPROPRIATE SPEED TAP. THEN PLACE
DISCONNECTED END OF JUMPER ON
"UNUSED" TERMINAL LEFT OPEN BY MOVING
THE SPEED TAP.

9. FOR LOW STAGE OPERATION ONLY, REMOVE
