Good afternoon Gent's.

I'm a owner of Skoda Octavia 1.4 TSI iV for the last year. Didn't had much time to around it, but I have noticed something strange should I call it.

There is any why to change the air-conditioning to use the traditional petrol engine instead of high voltage battery?

The battery level goes down dramatically when used for demisting front and back windscreen and heating seats.

If there is any way let me know please?

And also do you recommend using the app for remote control aircon unit? And another features?

Thank you in advance and stay safe

I've never heard of such a modification - it should be next-to-impossible because there's other functions that electric compressor is used for - other than climate. E.g. the hybrid system uses it to manage the HV-system temperature. So there would be lots of special coding to be done on various units that were not already done from the factory.
The main reason for this platform to use an electric compressor is that the PHEV concept is also intended to be used exclusively electric over short distances; this purpose would be unachievable if the compressor would be driven by the ICE.

The AC compressor is only used to cool the car or dry the air/interior, it's never used to heat the car. For that purpose the VAG PHEV platform uses a PTC heating element - which is obviously draining the HV battery. That's of course valid until the cooling liquid of the thermal engine heats up - and then it takes over the heating function. I'm not sure, but I think the rear window and the seat heating most likely use the 12V battery of the car as is the case on non-hybrid variants.

I'm constantly using the App to cool or heat the cabin when exterior temperatures are too high or too low. I'm also using it to control (start/stop) the charging process in some cases.

Thank you soo much for your reply.

I thought there was some setting that could be adjusted.

I didn't thought that the a/c will be fully electric.

But what about when you run out of battery and outside temperature are high like this summer, the a/c compressor will stop working?

A PHEV is never running out of battery completely... When your battery state of charge reaches 0% on the dashboard there's actually a battery capacity (not accessible by the user) that still has some charge left such that your car is still able to drive like a simple HEV - using electric or combustion-engine propulsion in a way that is fully decided by the hybrid system.
That battery capacity is sufficient to run the AC as the user/driver demands. When it gets too low, the ICE kicks in and generates some more electricity...
