If the measured temperature < SEt , Output : 0%.
If the measured temperature = SEt , Output : Minimum oMin % set value.
If the measured temperature < SEt + HYS , Output : 100%.
The output will be scaled to the according to temperature value (Max. 100%), when the
measured temperature is reached to the SET + HYS parameter value.
The output will be equivalent to the oMin parameter when the temperature value is reached
to the SET value.
If the temperature value is lower than the SET value, no output operation will be performed. Output rate %20
