The charging valve 1 switches on to the position „charge“ if all the following conditinos are true:
BufSupplyTemp <= OVHT-01 AND
BufSupplyTemp >= BufUpperTemp + CHG-01 AND
BufSupplyTemp > BufLowerTemp (if connected <> 999)
The charging valve 1 switches off to the position „closed“ if one of the following conditions is true:
BufSupplyTemp < BufUpperTemp - CHG-02 OR
BufSupplyTemp < BufLowerTemp (if the buffer lower temperature if connected <>999)
BufUpperTemp >= OVHT-01
