Upgradeed RA4 not showing numeric temp on Climate slider control

I have this same radio in my car and on the temperature slider it displays a numeric temperature that changes as you move it up and down. My new radio does not, it is showing just a gray rectangle. If I move the slider up and down, it does send warm or cold air but it appears that it can’t determine the temperature. I installed the climate control module inside the dash behind the right side panel exactly as directed. What do I need to do to gain full functionality of the climate control feature?
