9.4.3 Configuring a DHW tank with two sensors
When a domestic hot water tank with two sensors is connected to the
boiler, the loading of the tank depends on the water temperature
measured by the two sensors:
Loading of the tank will start when the top sensor measures a
temperature below (desired setpoint + CP700 – CP420).
Loading of the tank will stop when the bottom sensor measures a
temperature above (desired setpoint + CP700).
