The controller displays [COOR] in place of a temperature offset until the sensor comes within 0.3 C (0.5
F) above or below 0 C (32 F).
The controller displays the actual temperature offset when the sensor temperature is within 0.3 C (0.5 F)
above or below 0 C (32 F).
NOTE: The sensors should be in the ice bath a total of 15 minutes or more to assure the sensor
temperature has bottomed out.
