Carrier Control module 2-wire thermostat EcoBee Smart Thermostat
I looked at the thread Carrier Control module 2-wire thermostat EcoBee 3
and I have a similar situation where I am trying to figure out an extra wire. The control module wiring guide is the same as in the referenced thread.
OLD..................................NEW
Rh -------------> red ---------> Rh
W/W1 --------> white -------> W1

O/W2/B -----> orange -----> O/B (?)
Y1/W2 ------->yellow -------> ????
This is for a Carrier heat pump and A/C system. Looking to replace the thermostat with the latest ecobee

That is a very good question.
Is that a compressor stage or heat strip control.
That may be a terminal that can be configured either way.
We should probably look that up in the manual.
What is the model number of the old thermostat?
