A1 Error

What does an A1 error code mean?

Hello,

Cincinnati Sub Zero also manufactures an ECMO heater, which uses the same board but with different software. The A1 alarm is used on the ECMO to notify a difference of 1°C or more between the set point and actual water temp. However, that being said, the unit is operating with the incorrect software. I would strongly recommend contacting Cincinnati Sub-Zero for a replacement p/n 39958 control board.
