Fellas:

Anybody have any schmatics of the carrier optimizer?
Anybody have any idea how this thing works?
Sorry about the spelling.

Thanks

Carrier

Which one? Carrier made an Optimizer I, Optimizer II and the new Optimizer logic built into their electronic dual fuel tstat. I probably have schematics on all of these. Let me know which one you need. -DF

INFO.....

The 1 used an O.D. stat with a isolation relay on the O(reversing valve). They did not hook up W2 at tstat. They took Y from t-stat to OD stat which either went to contactor or furnace depending on setting and temp. They take O (from tstat) and common to coil side of relay. They take R and O (to heat pump) to the normally open relay contacts. This prevents backfeed. They do this to prevent furnace and H/P from running together. Make sure H/P has high pressure switch. GOOD LUCK
