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 > BufMid1Temp
The charging valve 1 switches off to the position „closed“ if one of the following conditions is true:
BufSupplyTemp < BufUpperTemp - CHG-02 OR
BufSupplyTemp < BufMid1Temp
BufUpperTemp >= OVHT-01
The charging valve 2 switches on to the position „charge“ if all the following conditinos are true:
BufSupplyTemp <= OVHT-02 AND
BufSupplyTemp >= BufMid1Temp+ CHG-01 AND
BufSupplyTemp > BufMid2Temp
The charging valve 2 switches off to the position „closed“ if one of the following conditions is true:
BufSupplyTemp < BufMid1Temp- CHG-02 OR
BufSupplyTemp < BufMid2Temp
BufMid1Temp >= OVHT-02
The charging valve 3 switches on to the position „charge“ if all the following conditinos are true:
BufSupplyTemp <= OVHT-03 AND
BufSupplyTemp >= BufMid2Temp + CHG-01 AND
BufSupplyTemp > BufMid3Temp
The charging valve 3 switches off to the position „closed“ if one of the following conditions is true:
BufSupplyTemp < BufMid2Temp - CHG-02 OR
BufSupplyTemp < BufMid3Temp
BufMid2Temp >= OVHT-03
The charging valve 4 switches on to the position „charge“ if all the following conditinos are true:
BufSupplyTemp <= OVHT-04 AND
BufSupplyTemp >= BufMid3Temp + CHG-01 AND
BufSupplyTemp > BufLowerTemp(if connected <> 999)
The charging valve 4 switches off to the position „closed“ if one of the following conditions is true:
BufSupplyTemp < BufMid3Temp - CHG-02 OR
BufSupplyTemp < BufLowerTemp (if the buffer lower temperature if connected <>999)
BufMid3Temp >= OVHT-04
