of all controllers within the network.
The total flow rate is calculated and displayed in each controller next to the icon for the valve.
The sensor values S1 to S6 are exchanged through CAN. First it is verified whether a local sensor is connected and if this
is the case, it will be used and its value transmitted through the CAN bus to the connected controller. If not, a value from
the CAN bus will be used.
Special features
1 The circulation pump is not controlled by the cascade. If there is a circulation pump connected, all the necessary
settings must be made using the controller the pump is connected to.
b
If the fresh water cascade is operated with a circulation pump, the correct hydraulic integration of the circulation
pump must be ensured. In such a case the circulation pump must be connected hydraulically outside of the cas-
cade.
2 If no fixed base is set, the cascade stations will rotate base operation. The entire duration of each station is recorded
in order to ensure an even distribution of operating times.
Signal V2
With this function, the PMW / 0-10 V output 2 can also be used to control an additional high-efficiency pump. If a pump
function is activated (e. g. circulation, solar, additional pump,...), additional settings for pump settings V2 and speed con-
trol V2 can be set or adjusted. Please pay attention to the technical information for the PWM/0-10V outputs.
Pressure Monitoring
In this menu, the system pressure monitoring can be activated through a direct sensor. Once the set pressure conditions
are exceeded, a message is generated and the LED flashes red.
RPS-Type
Type of pressure sensor
In this menu, you can adjust which pressure sensor is being used. Please note: If e.g. VFS1 is connected, RPS1 option
is not shown.
Pmin
Minimum pressure. If this pressure is not met, the controller emits an error notification and the red LED flashes.
Pmax
Maximum pressure in the system. If this pressure is exceeded, the controller emits an error message and the red LED
flashes.
Sensor Calibration
Deviations in the temperature values displayed, for example. due to cables which are too long or sensors which are not
positioned optimally can be compensated for manually here. The settings can be made for each individual sensor in
steps of 0.5 °C.
b
Settings are only necessary in special cases at the time of initial commissioning by the specialist. Incorrect meas-
urement values can lead to unpredictable errors.
Commissioning
Starting commissioning help guides you in the correct order through the basic settings necessary for commissioning, and
provides brief descriptions of each parameter in the display. Pressing the "esc" key takes you back to the previous value
so you can look at the selected setting again or adjust it if desired. Pressing "esc" more than once takes you back to the
selection mode, thus cancelling the commissioning help.
b
May only be started by a specialist during commissioning! Observe the explanations for the individual parameters
in these instructions, and check whether further settings are necessary for your application.
Factory Settings
All settings can be reset, returning the controller to its delivery state.
b
All of the controller‘s parametrization, statistics, etc. will be lost irrevocably. The controller must then be commis-
sioned once again.
Time & Date
Serve to set the current time and date.
For time-dependent functions such as circulation and anti-legionella and the evaluation of system data, it is essential that
