After switch between Celsius/Fahrenheit, the temperature set-point of parameter item St automatically adjusts to the
corresponding temperature value of Celsius/Fahrenheit, and the temperature set-points of other parameter items related
to Celsius/Fahrenheit automatically adjust accordingly.
For example, St is set to 0
℃
, and it will automatically adjust to 32
℉
after switch; C4 (calibration value of cabinet sensor)
is set to +8
℃
,and it will automatically adjust to +20*(8/10)=+16
℉
.
Suggestion: Switch Celsius/Fahrenheit first, then adjust the value of related parameter items to ensure correct parameter
configuration.
