5 Tank Priority
5.1 Systems with two tanks (Systems 2, 3, 9, 10, 13 and 17)
5.2 Systems with three tanks (Systems 11, 14, 15 and 18)
If the value of "dT" (T1 minus T2/T4) reaches the value required for charging, tanks 1 and 2 are
separately charged until the tanks reach the maximum temperature.
Priority for tank 1 (for Duplex)
For Multiplex systems 9, 10, 13 and 17 tank 1
always takes priority
Priority to tank 2 (for Duplex)
If T1>T2 and T2<T2 max (regardless of T4)
If T1<T2 and T2<T2 max and T1>T4 and
T4<T4 max
Charge tank 2 synchronously
Priority charging time/Priority pause time
If T1>T4 and T2>T2 max and T4<T4 max
If T1>T2/T4 and T2>T2 max and T4>T4 max
If the value of "dT" (T1 minus T2/T3/T7) reaches the value required for charging, tanks 1/2/3 are
separately charged until the tanks reach the maximum temperature.
If T1>T2 and T2<T2 max (regardless of T3 and T4)
If T1<T2 and T2<T2 max and the value of "dT" (T1-T3/T7)
reaches the values required for charging, tanks 1/2/3 are
separately charged until the tanks reach the maximum
temperature.
Synchronously charge tank 2
