Controller operation

In normal operation the controller displays cabinet temperatures

in degrees C (default) or user-selected degrees F. Degrees C

temperatures are displayed to 1 decimal point.

The controller is pre-programmed with a +3.5 C (+38 F) set point

which provides a compressor cut-in at +3.5 C (+38 F) and cut-out at

+5.0 C (+41 F).

All set points have a 1.5 C differential. The 1.5 C differential means

that with a +3.5 C set point, for example, the compressor will turn off

at +3.5 C (+38 F) and turn on when the cabinet temperature reaches

+5 C (+41 F).

This temperature may not re ect the temperature of the blood

products in the refrigerator. The temperature of the blood products will be re ected on the recorder chart and the

recorder's digital temperature display. At times there may be a difference between the two displayed temperatures.

Adjust the controller SET value to achieve your desired blood product temperature as displayed on your chart

recorder.
