Process description
The consuming circuit keeps the temperature of the tank at 63°C. In this case, the set point of the
boiler = the set point of the consuming circuit (63°C).
If the sensor inside the tank detects a temperature = the set point of the DHW (61°C) -5°C, the
DHW cycle starts. The output temperature of the boiler is then = the set point of the DHW (61°C)
+ over-value (7°C) = 68°C.
The DHW cycle stops when the sensor inside the tank reaches the DHW set point temperature
(61°C). The boiler then returns to the set point of the consuming circuit (63°).
