iOS Climate Conflict (HA Climate vs Tado)

Hi all,

I present my AC Unit via HomeKit through HA on the Climate options. My AC Unit is controlled using an ESP32 connected to H-Link bus on the AC unit itself.

When using Siri to control my Air Conditioning unit and set the temperature. It is also turning on the radiator (Tado, linked via official Tado integration). Why is this? Can they be separated?

For example;

“Hey Siri, set the air-conditioning to 16 degrees with a high fan speed”

You can see the results in the picture. Including the fact the AC unit actually went in to heating mode.
