CONTROLLER
HI-LO ALARM
The Medi+ controller features a built in audio/
visual Hi-Lo alarm. If the temperature within the
cabinet storage area exceeds the factory set alarm
temperature and duration, the control will display
a temperature alarm and activate a sounder. The
alarm can be cancelled by pressing the
“i”
button.
PROBE FAIL SAFE FEATURE
The Medi+ controller features a special fail-safe
condition. In the event of a temperature probe
failure the compressor will not continue in normal
sequence.
Instead the compressor will switch to a five minute
cycle, which it cycles on for five minutes then off
for five minutes. The normal compressor cycle
will be restored upon the repair of the probe fault.
This feature is designed to avoid the compressor
overheating and protect the stored contents of the
equipment until manual intervention is possible.
