Well I opened up the automatic transfer switch yesterday to check connections, etc. All the connections were tight and there was no obvious evidence of a problem, although the contacts were pitted on the generator side of the relay. I ordered a new transfer switch, but I doubt that it was giving me any trouble, since it is on the power cord side that I am having issues when running my rear A/C unit.
Doug,
You seem to be pretty knowledgeable about the Penguin II. Can you tell me how I would be able to identify whether or not my unit has the 12 to 5 button conversion kit? I have the 5 button thermostat controlling both my original Penguin unit up front and my "new" Penguin II unit in the rear.
One thing that may be a clue here, is that although I am able to select either unit 1 or unit 2 using the zone button, both number 1 and 2 are always visible on the display. I don't recall seeing both unit numbers displayed at the same time on the same style 5 button thermostat in my old Dutch Star, with the 2 Penguin units.
Any thoughts?
And thanks for all the assistance from all of you so far.
Roland
