7/12
Parameter list PA2 (cold regulator)
Access: Set key switch 1 to position P, press buttons 3 and 8 simultaneously for 4 seconds, select PA2 using button 3, keep
button 12 pressed and set -7 (minus 7). Now button 3 or 8 can be used to scroll through the parameter list.
The value of the parameter selected is displayed when button 12 is pressed. It can be adjusted by pressing button 3 or button 8
in addition. The new value is stored immediately when button 12 is released.
The value is automatically reset to the original value if no key is pressed for 45 seconds or by simultaneously pressing buttons 3
and 8 for approx. 4 seconds.
