Thnx everyone for the input . I intend to do this the next couple of days (first chance I get work has been crazy ). I have residental hvac experience and when doing home hvac there is a table that list the other variables like ambient temp etc. That are useful.... I would love to have a copy of that table if it exist...... Are there are any techs out there that might share this with us . But with the info I have recieved this far I feel confident this will rectify my problem... If I am successful in recieving the table I spoke of I will consider doing a diy on this but I would like to insure I have all pertinant information before posting such ..... Thanks again to everyone on the forum you guys are the best
