10.11.2 Primary flow temperature sensor
With plant types DHW 4 and DHW 5, a primary flow temperature sensor can be
configured as an option.
In that case, mixing valve control with plant type DHW 4 is accomplished via the
primary flow temperature.
If the primary flow temperature sensor is configured, its temperature will be used during
active DHW charging to ensure discharging protection.
The function is to be activated via "Extra configuration":
Main menu > Commissioning > Extra configuration > DHW > Inputs > Primary flow
sensor Assign terminal
There are no settings required.
10.11.3 Circulating pump
A circulating pump can be configured for DHW circulation.
The output is to be activated via "Extra configuration":
Main menu > Commissioning > Extra configuration > DHW > Outputs… > Circulating
pump Assign terminal
Control can take place via a specific time program or depending on user requirements
(DHW time switch). Using setting Acc to DHW time switch, the circulating pump will
run during operating mode "Normal
".
By activating the circulating pump for the period of time the legionella function is
performed, the circulation pipe can also be protected against legionella viruses
For detailed information, refer to subsection 10.6.2 "Sequence of legionella function".
