Scrape integration: i need help to send another mode to my dimplex (simular weishaupt?) heat pump with pcoweb module

Here is an example of what the configuration page looks like: http://62.147.201.147/http/index/j_modus.html
I am now trying to send the same post to my heat pump via Postman, which is necessary to switch from summer to party, for example.
I would like to make most of the settings for the heat pump from Home Assistant.
