I got the call at 0600 this morning on the chiller, said it was a Transition fault, chiller was running. They looked at the code and returned to operating window of 74. Said it was no longer flashing. Told me to wait till Monday, not to run the call. Of course I couldn't go back to sleep. I don't have my manual at home on the unit. They didn't toggle the unit off, is it truly reset? What is this fault?
