Had a co-worker looking at a foursome of RTAC's last week in the cold weather the building guys were saying that 2 of them would not start . ( part of their freeze protection scheme) the 2 chillers that would not start due to run inhibited, saturated condenser temperature below 25 degrees. So he called Trane tech support and told him that was the case live with it. Btw the units don't have low ambient. The Trane tech support guy would not elaborate on the reasoning as to what damage this would cause . Does anyone else know the reason for this?
