99.9 C
Function: To set maximum allowable high
temperature limit and alarm.
Example:
Setting this parameter at
0
99.9 C will not allow the set point to go
0
above 99.9 C. Also if the temperature
0
reaches or goes above 99.9 C.the display
will show High Temp. Alarm & at this point
the alarm will activate.
Once set at a particular range, this will
not allow the set point to go above this
range.
