Functions and parameters
2.1.2 Tapping detection using the water flow sensor
In contrast to the DHW tapping recognition with a flow switch, the extent of tapping is indi-
cated as well as when the DHW tapping starts and finishes.
By activating the optimizing function
Adaptation , the device adapts itself to changing net-
work conditions without having to change the control parameters (see section 2.6). The opti-
mizing function can only be activated when a water flow sensor is used.
Hot water being tapped is also detected when the maximum flow rate of the water flow sen -
sor is exceeded.
Functions WE Configuration
F05: Current input 1 F01 - 1
F06: Function of current input 1 F02 - 1
F07: Measuring range of current input 1 F07 - 1
2.2 Set point changeover
The device can use two different set points, W1 and W2, for control, e.g. hot water tempera-
ture in normal used and for thermal disinfection. The set points changeover is implemented
by the binary input (BI1):
− BI1 open: W1 is the set point
− BI1 closed: W2 is the set point
It is only possible to change between set points W1 and W2 when the DHW temperature is
measured with a Pt 1000 resistance sensor (F05 - 0).
When the binary input BI1 is used, the current input cannot be used. It also not possible to
deactivate
the function to maintain the heat exchanger at a constant temperature (see sec -
tion 2.3) when the binary input is used for set point switchover.
Functions WE Configuration
F05: Current input 0 F05 - 0
F08: Function of binary input 0 F08 - 1
