wiring for an old Rheem heat pump to T-stat
I need a basic wiring diagram for an old Rheem heat pump. Wiring connecting to T-stat to Air handler to Heat Pump.
Tstat: B (blue) O (Orange) G (Green) Y (Yellow) W (White) R-Rc (Red)Air Handler: R C G W1 W2 Y
Heat Pump: Y B C R D
This what I have wrote down. My question is how or where should i get my common connected from Tstat-Air-Heat?
T-stat -----------------------> Air -------------------------------------> Heat
R jump Rc--------------------- R---------------------------------------R (Red)
W --------------------(W1 (wht/blk - W2 (wht/blu) -----------------D (purple)
Y ---------------------------------Y----------------------------------------Y (yellow)
G----------------------------------G
O (Not used)
B ----------------------------------------------------------------------------B (blue)
C - ?????????????????? C (brown) -----------------------------C (brown)
My T-Stat doesn't have a "C"

Tstat C connects to the same spot as heat pump C.
You will have 2 wires on the air handler C.

Thermostat ----------- air handler ---------- condenser
------B -------------------------------------------------> B
------G ----------------------> G
------Y -----------------------> Y ---------------------> Y
------W ----------------------> W1 -------------------> D ?
----- R/Rc ------------------> R ----------------------> R
------ C ---------------------> C ----------------------> C
The confusing part is the orange wire on O at the stat. If the orange is not connected at the air handler...... yes..... you can use that orange wire as a common between the stat C and the air handler C.
