Thermostat not powering on

Long story short, I am installing a wyze thermostat for airbnb.

I had a jumper for e to aux, my understanding is that is for emergency heat and of no concern for power.

I followed directions exactly and can’t get it to turn on. Thoughts?

Thanks!

You need to check the furnace side of the wires and make sure the blue wire is connected to C. Also make sure the fuse isn’t blown.
If you still need help, post a picture of the furnace side of the wires here and I will attempt to assist.
