Nest thermostat Connecting to older Honeywell hemostat

[Roadcorreo]

Hey there. any one else has the problem with extra wiring. The nest  Mirror hemostat only has 6 terminals. Other model I have 8 terminals. where do we go with the extra wires?

There isn't  enough information on Google for the specific low cost product!

NOT a Do It Yourself type product.

@Roadcorreo ,

If you search for “Nest Compatibility” you would have found the Google Nest Compatibility Checker: https://store.google.com/intl/en/widget/compatibility/thermostat/

just input your wire terminals that were being used, and it will advise on which Nest Thermostats are compatible with your system.  If you chose the basic Nest Thermostat because it was less expensive, you will not have support for multistage heating or cooling systems.

Thanks for the answer 

In google nest help page comes up a directional  o/b  via menu ? 
when the nest run a test it worked fine. After I installed google home it display cool and blew heat? Can I try that?

The O/B is the control wire for the Heat Pump reversing valve. The valve switches the Heat Pump form Heat to Cool or Cool to Heat.  There are two Heat Pump styles out there. They are called O models or B models.  O models are by default Heat models and B models are by default Cooling models.  You might need to change your mode From O to B.  Check your SETTINGS > EQUIPMENT > HEAT PUMP.
