Auto climate control system indentify 700

Hello: I have a 91 740 & 940 wagons, both B230FT. How do I tell if I have automatic climate control vs non-auto? I am going to replace both htr control valves but there appears to be two types (auto & non)?

Auto climate control system indentify 700

Manual climate control (MCC) has a sliding or rotating heat selector on which you manually choose the temperature of the air. The automatic climate control (ACC) has a selector marked with temperature set points which automatically controls the temperature of the interior of the car by adjusting outlet air temperature. Electronic climate control (ECC) does the same thing electronically.
