The climate parameter Heat Cool in knx is not recognized by knx. They are converted into 0x01, 0x03 and other values and transferred to the knx bus. Ha has made these values into fixed values, but the actual knx manufacturer does not completely follow this parameter. The preset point made many knx climates controlled by ha and cannot be used. Many people also reported this problem on the forum, but the replies were all inconsistent. In fact, the responders did not carefully look at the essence of the problem. This requires the developer to tell the user in which file the Heat Cool is changed to 0x01 0x03, or whether to consider making a customizable function. Taking care of the 40% of users who use knx? ?
