Settings on the Rubis
Adjust the outlet temperature set point on the Rubis to 58°C.
Summary of the rules for the adjustment of the set points for the DHW
Set point of the consuming circuit (low limit) = set point of the outlet T° of the Rubis +5°C
Set point of the DHW on the boiler = set point of the outlet T° of the Rubis -2°C
Over-value of the boiler outlet temperature when the DHW is restarted = 13°C
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 (56°C) -5°C=51°C,
the DHW cycle starts. The output temperature of the boiler is then = the set point of the DHW
(56°C) + over-value (13°C) = 69°C.
The DHW cycle stops when the sensor inside the tank reaches the DHW set point temperature
(56°C). The boiler then returns to the set point of the consuming circuit (63°).
