I just picked up a H10-PM today and need a little clarification on the settings when running in automatic mode. The manual says to use the medium switch position on R-22. The manual doesn't spell it out but the way I interrupt is that one would want to use the small setting for 410A. R-22 and 410A is the only two refrigerants that I work with so any constructive input on the setting when using the automatic mode would be much appreciated. Thanks in advance.
