HUD home purchase. former owner torn a lot of things out before leaving. We have 8 wires coming out of wall where the thermoststat goes> Wire colors are:

Brown

Any suggestions to where which wires go? None were labeled. We have a Nordyne split system heat pump. Thanks for your time.

Remove the panel to your unit and write down the wire connections that were made there.
