Just tried installing nest from an old Honeywell thermostat that powers HVAC (Heating / Cooling / Fan).
Heat pushes not hot air.
Cool pushes hot air
Attached is the current nest configuration and back of the old thermostat with wire configuration...

Your nest thermostat is not set up properly for your heat pump. You can ignore the white jumper wire between Y and W, however, the white wire that was attached to O on your old thermostat needs to connected to the O/B of your Nest thermostat.
Start your setup over, the wires I use are:
Red on R to Nest R.
Yellow on Y to Nest Y1
Green on G to Nest G
White on O to Nest O/B
Your equipment type is Heat Pump.
Now the Nest works best with a Common wire and your cable has an unused Blue and Brown conductors. You can check the HVAC equipment and see if the blue or brown wire is attached to a C terminal.
Good luck!

Done!
I will all look to see if the HVAC unit has brown/blue/common connectors when I get access to it (condo unit) but glad to see the wiring is already there!
Thanks again!

Patrick, if you live in a Condo, your air handler is likely inside your condo unit. In an alcove perhpas?
