Summary of the rules for DHW set point adjustment on the STRATTON MK3
Setpoint of consuming circuit 1 (1859) = setpoint C1 Rubis + 10°C = 68°C
DHW setpoint (1610) = setpoint C1 rubis - 2°C = 58°C
Boiler setpoint temperature over-value (5020) = 16 °C
Process description
The consumer circuit maintains the tank temperature at 68°C. In this case, the boiler
setpoint = consumer circuit setpoint (68°C).
If the sensor inside the tank detects a temperature = the set point of the DHW (58°C),
the DHW cycle starts. The output temperature of the boiler is then =
the set point of the DHW (58°C) + over-value (16°C) = 74°C.
The DHW cycle stops when the sensor inside the tank reaches the DHW set point
temperature (60°C). The boiler then returns to the setpoint of the consuming circuit
(68°).
