6.6.13 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.
WARNING: Valid only in case of inverter type M/M. There could be some pressure increasing in the system, thus the
starting frequency must be close to the rated one for a while, in a single-phase pump, to enable its turn on (see
sections 6.6.17 and 6.6.18) each time that comes on the antifreeze to utilities closed conditions can increase the
pressure in the system.
Valid only in case of inverter type M/M. Please check your pump can face the system prevalence. If
not, its better not to enable the anti-frost function.

6.6.14 AF: Anti freeze

If this function is enabled the pump is automatically rotated when the temperature reaches values close to freezing
point, in order to avoid breakages of the pump.
WARNING: Valid only in case of inverter type M/M. There could be some pressure increasing in the system, thus the
starting frequency must be close to the rated one for a while, in a single-phase pump, to enable its turn on (see
sections 6.6.17 and 6.6.18) each time that comes on the antifreeze to utilities closed conditions can increase the
pressure in the system.
Valido solo in caso di inverter di tipo M/M. Please check your pump can face the system
prevalence. If not, its better not to enable the anti-frost function.
6.6.15 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. Inputs I2
and I3 are available only on type M/T and T/T inverters.
For electrical connections, see section 2.3.3.
The inputs are all the same and all functions can be associated with each. The parameter IN1..IN 3 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.
