The other switch is a pressure switch for the LOW speed fan function. It will engage the fans at low speed only if refrigerant pressure exceeds some limit. The fans DO NOT come on automatically with the compressor.

As you can see, the R/D has only one sensor. Not sure why. All works perfect wrt cooling. Only the aux fan is suspect.
Not sure which role that red sensor plays.
