Replacing Thermostat, confused about wiring configuration.

I have a W and a O wire in the configuration of my original thermostat. Do I need to take the O Wire and put it in the W slot (since it has O/B next to it) and take the W wire and put it in the W2 slot of the Honeywell?

Just need some help, thank you!

 

Welcome to the forums.

Your old wiring shows a heat pump with back up electric heat. Is that correct ?

If that is correct - this is your wiring......

White ----- > AUX / W2
Orange ----> O/B / W
Green -------> G
Red ----------> R [put switch in R & Rc position]
Blue ---------> C
Yellow -----> Y

 

Do I need to make a jumper between the R and Rc?

 

No...... Since your old thermostat had only one R-wire connected,
make sure the slider tab is pushed up to cover the RC connection.

 

Thank you! I ran into complications last night, the Lyric unit kept displaying there was no power to the unit. I turned the power off to the AC unit at the outside breaker box beforehand, but I guess that didn't turn the power off the main unit inside. So while wiring the Lyric, wires touched at one point and it caused a fuse to blow and that's why it wasn't displaying any power to the unit on the Lyric. The guy we had coming out today to refill the freon, took a look at it and replaced the fuse, but he advised the wiring was correct to the Lyric. So again, thank you PJmax!

 

You're welcome. Lesson learned.... no problem.

 

A multimeter is your friend.
