Help with 6 wire heat pump connection

After a/c company installed new heat pump system everything worked as it should. I installed nest Gen 4 and could only heat the house using emergency heat setting.  Should I put the * wire to W2 instead?

Post a picture of the original thermostat's wiring here if you can.

If the camera icon isn't present yet, you can use the Igmur.com site and post the link it provides here.

Click on the green New Post link in the upper left corner of the site.
