Alexa & Smart Skills for someone with basic skills

Hi guys – I have the SmartThings app installed on my iPhone 13 Pro Max. I have the Alexa smart skill for SmartThings installed. When I ask Alexa to turn the ducted air conditioning on, she does, but it’s not the last setting on the wired controller, but a totally different setting. I cannot find where I change this though – can anyone assist me?

Try " Alexa, set the air conditioning to xx degrees" or “Alexa, set thermostat to xx degrees” or some variation that includes a temperature setting.
