Instructions for AC Control V3 touch pad?

Are there any specific instructions on how to use the touch pad? It’s the middle of winter here and 80% of the time when I turn on the heat pump from the touch pad it goes to COOL mode. Sometimes if I go off and on again a few times it’ll turn to HEAT which is what I want. But I can’t figure out how to reliably do this? Am I missing something? I don’t have any schedules set up, I usually just manually turn on / off via app or device. I specifically purchased Tado because of the touch screen but it’s proving annoying.
