Hello, has one of you ever measured the three-pole pressure switch of the climate on passage?? I get the values: From the middle to the left connection —- No passage From the middle to the right connection — 20 K Ohm From the left to the right connection — 12 KOhm everything seen in the direction of travel. I understand the switch like this: If the gas values are in order this passage. If the pressures are abnormal, the respective switch opens and the system switches off…. Do I make a mistake of thinking? Many greetings from the elk
