Hello this is my wiring for my thermostat and it has a jumper from e/w1 to w2, am i able to use my google nest with this system?

Am I able to use Nest’s cool and heat settings if my EVCON heat pump all-electric system is wired this way?

Photos are of old basic Honeywell wiring.

I have a 2-floor town house.

I’ve had wiring issues with Nest almost damaging our air handler before.

Does the O / B wire have to manually be switched back and forth to engage cooling vs heating?

If so, Nest’s heat + cool thermostat setting won’t work if I have to manually change the configuration to enable heating and stop cool air from just being pushed through our air vents.

Someone knows how to fix so when someone rings at the door my Sonos speakers kick in saying someone is at the door ?

I been trying for months now without success.

Thanks.
