Cylinder 1 maximum temperature
Menu: Service > Settings > Cylinder 1 maximum temperature
When the temperature detected by the cylinder temperature sensor reaches the maximum cylinder
temperature, charging of the cylinder is stopped.
7.5.7
Double Match Flow
Menu: Service > Settings > Double Match Flow
This function is used for quick charging of the top part of the cylinder to 45 °C to reduce the amount
of time the domestic hot water is reheated by the boiler.
This function is only possible when
Speed modulation
is active.
If the
Daily heating
function is also used, the
Double match flow
function may be limited as the
necessary sensor position for
Daily heating
(top 1/3 of the cylinder) may be within the part of the
cylinder reheated by the boiler.
7.5.8
Return boost cut-in temperature differential
Menu: Service > Settings > Reserve bypass cut-in temperature differential
If the Return boost function is active, the temperature of the solar storage cylinder is compared with
the return temperature of the heating system. If necessary, the return boost valve is opened to feed
heat from the solar system from the thermal store into the heating system.
The minimum difference from the cut-out temperature difference is 3 K (°C).
