Analog Input scaled for a signal of 0-5V
Using the Slave configuration ("Input Type" register = 3) it is possible to drive a fan at its max speed using a
signal 0-5V, without changing the max speed register configuration.
Constant Airflow curve example
In figure 23 are shown 4 constant airflow curves randomly chosen.
It is possible to modify the max and min constant airflow values (within the limits
indicated in Table 3 pag. 23) by modifying the Modbus parameters in the holding register
42 and 43.
The max airflow (Reg. 43) must be always higher than the min airflow value (Reg. 42).
