wow.. that is exactly what i'm looking for..thank you for the link - and thank you wally for the write-up - now i can test this system and see what i got going on - i did see where wally said the auto system does not control the fan speed so i wonder why mine turns on and off (seemingly at random) - the fan control switch works the fan at every speed correctly but if it's set to "0" it will just come on for 5-10 seconds then stop then repeat that every 5 minutes or so - i was thinking that was the head unit trying to get the temp to the set range but now...??? - thanks again
