Hi there 

I got new nest thermostat . The old one is Honeywell with four wires  : the diagram  connection is like this 

Red wire o -R 

Yellow - Y 

Green - G

White -O

and there is bridge RC-RH

the nest  has only one R no RC/RH and   As they explained in the video we dont need the bridge . Now the AC is heating only !! Any thoughts how to connect it please ?

You have a heat pump system and need to wire it like this.

Red - R to R (jumper not needed)

Yellow - Y to Y

Green - G to G

White - O to */OB

@Patrick_Caezza Thank you Patrick . I think I tried thus connection but It gave me hot air .!!    

[Patrick_Caezza]

Do you have access to the furnace/air handler?

If yes, look at the control board and verify where each wire is connected.

The white wire being connected to the blank terminal on the thermostat confuses me a bit.

@Patrick_Caezza  The unit on the roof and its two stories twon house. The white wire connected to the O terminal .

Ouch.

When you set up the Google Nest Thermostat, which wires did you tell it you had when it asked?

This is the Google Home app screen I'm referring to.

@Patrick_Caezza I think I should start over setting the thermostat . Can you help me with video showing the steps of setting the thermostat for heat pump unit please ? 

[Patrick_Caezza]

I don't usually provide video links as I never review them for accuracy.

First, you need to factory reset it.

Then you'll need to set it up again.

Wire it like this.

Red - R to R (jumper not needed)

Yellow - Y1 to Y

Green - G to G

White - O to */OB

When asked by the Google Home app which wires do you have, select these.

R, Y/Y1, G/G1, and O

This should configure the thermostat correctly.
