• Factor > 50%: ∆p‑v characteristic curve becomes flatter. Factor 100% is equal to an Δp-c control.
The excessive or inadequate supply can be compensated by adjusting the factor:
• In case of inadequate supply in the partial load range, the value must be increased.
• In case of excessive supply in the partial load range, the value can be reduced. More energy can be saved
and flow noises are reduced.
9.2.7 Multi-Flow Adaptation mixer (from SW ≥ 01.05.10.00)
In the case of secondary loop with in-built 3-way mixers, the mixed volume flow can be calculated so that
the primary pump takes the actual demand of the secondary pumps into account. To do this, the following
has to be carried out:
Temperature sensors must be mounted on the secondary pumps in the respective feed and return of the
secondary loop and the heating or cooling quantity measurement must be activated.
Temperature sensors are mounted on the feeder pump at the primary feed upstream of the heat exchanger
or hydraulic shunt and at the secondary feed behind it. The function Multi-Flow Adaptation mixer is acti-
vated on the feeder pump.
9.2.8 Detection of thermal disinfection
The Stratos MAXO-Z uses a sensor connected to the hot water tank or the hot water output line to detect
when the hot water temperature exceeds a specified limit value. It detects that thermal disinfection has been
started and thus continues to supply at full speed.
The "Detection of disinfection" function has been provided in the "Set control mode" menu after the "Drink-
ing water – temperature T-const" application has been selected in the settings assistant.
This function monitors the feed temperature at the hot water source with an external temperature sensor in
order to record the significant increase in temperature in case of thermal disinfection.
Once the system detects thermal disinfection, the pump switches to maximum output to support disinfec-
tion and rinse the system with hot water.
NOTICE
If the "Detection of disinfection" option is not used, the pump reduces the power when it
detects a temperature increase. Thermal disinfection is prevented.
9.3 Settings assistant
Thanks to the settings assistant, it is no longer necessary to be familiar with the matching control mode and
additional options of the corresponding application.
You can select the matching control mode and additional options in the application's settings assistant.
You can also directly select a basic control mode in the settings assistant.
