With F08=4 the ST2 output is activated when the temperature reaches a value equal ST1 minus the
configurated value in F09 (ST1-F09), or when the temperature reaches a value equal ST1 plus the
configuratedvalueinF10(ST1+F10)
Ex.:
- Temperature in ST1 = 25 ºC
- Value in F08 = 4
- Value in F09 = 2
- Value in F10 = 5
