@Ngreenhalgh 

Do you have a picture of the original thermostat wiring that you can post?

There is no standard on what the different wire colors do, so you can't just go by that.

I don’t have a picture, but I did write it down…

Y- yellow

c- blue

w- white

g- green

rc- red

jumper between r and rc

Hello folks,

I wanted to stop by and see how I could help.

Thanks for lending a hand, @Patrick_Caezza.

@Ngreenhalgh, I appreciate you sharing the photos. It appears to be a heat pump issue you're experiencing. To be sure, what type of HVAC system do you have? Is this a conventional type with heating and cooling only or a heat pump? Also, could you share with us the make and model of your HVAC system?

I'll look forward to your response.

Regards,
Mark
