Description
The function allows you to enable the remote sensor and select
the installed sensor type. It is also possible to rename the sensor
for easy identification, for instance by using the street name or zip
code.
You can enter a setpoint for the sensor. Based on the logged
data, CU 354 controls the outlet pressure at the pumping station
to achieve the set pressure at the remote sensor.
The sensor can be set to give an alarm if the pressure falls below
the defined minimum pressure.
You can see when the latest response from the remote sensor
was received. The remote sensor will send the logged data once
every 24 h (normally during the night).
