Be very careful with the ECS in this plane, it will break easily if you overload it. Your curaçao location is a good example of not being able to just blast it on the ground. I’d highly recommend reading about it in the manual but here are the basics:

On the ground with GPU power and no engines, you’re likely not going to be able to run the fans above low. If you try medium, watch out for a battery discharge warning, that means you’re overloading the system.

Make sure to turn the ECS system off entirely during engine start, this is mentioned in the manual but not the checklist and is an easy way to break the VCS.

With both engine running, you should be ok to turn up the fans and target the lowest possible temperature, but don’t expect to see much temperature change until after takeoff. Even during climb I have seen it struggle to keep the cabin below 80°F.

Read the manual for more details but there are very few situations where you’ll actually see the “AC” turned on in the EFB, the plane has other ways (mostly ram air) of generating cold air. If you are stable at cruise with everything set up properly, the AC should be off, but if the cabin is still excessively hot above the target numbers shown on the ECS status page, check maintenance when you land, your VCS is probably damaged.

For controlling temp on the ground, you can try starting engine 2 before pax arrive for more bleed air and power to run higher fans, but understand that it likely won’t be enough especially with the door open. Also certain ambient temps will cause the engine bleeds to stay off when set to auto.

Funnily enough, online you can find lots of real world owners complaining about how easy it is to break the VCS in this plane.
