6.6.12 AE: Enabling the anti-blocking function

This function serves to avoid mechanical blockages in the event of prolonged disuses; it acts by periodically
activating the pump in rotation.
When this function is enabled, every 23 hours the pump complete an unblocking cycle lasting 1 minute.
6.6.13 Setup of auxiliary digital inputs IN1, IN2, IN3, IN4
This section shows the functions and possible configurations of the inputs by means of parameters I1, I2, I3,
I4. For electrical connections, see section 2.2.4.2.
The inputs are all the same and all functions can be associated with each. The parameter IN1..IN4 enables
the user to associate the required function with the input of the same name.
Each function associated with the inputs is explained in more detail further in this section.
Table 22 summarises the functions and various configurations.
The default settings are those in Table 21.
