AUTOMATIC MODE:
In
Automatic mode
the RDCV is a “master” device, i.e. it needs to be connected to
a sensor via Modbus RTU in order to operate and control the environment based
on the information received by the sensor. If no sensor is connected, the display
will show “...” and the RDCV will not work. The sensor needs a few seconds in order
to take samples from the environment.
