6.6.15.1 Disabling functions associated with input
If an input is configured at 0, each function associated with this input will be disabled, regardless of the signal on the
terminals of the input itself.
6.6.15.2 Setting the external float function
The external float can be connected to any input, for all electrical connections, refer to paragraph 2.3.3.
The float function is obtained by setting the parameter Ix, for the input to which the float signal has been connected, on
one of the values in Tabella 23.
Activation of the external float function generates a system block. The function is envisaged to connect the input to a
signal from a float that indicates a water supply failure.
When this function is enabled, the symbol F1 is shown on the STATUS line of the main page.
The input must be activated for at least one second for the system to block and indicate the error F1.
When in the F1 error condition, the input must be deactivated for at least 30 seconds before the system unblocks.
The function behaviour is summarised in Table 23.
When several float functions are configured at the same time on different inputs, the system indicates F1 when at
least one function is activated and clears the alarm when none are activated.

6.6.15.3 Setting the auxiliary pressure input function
Auxiliary pressures P2 and P3 are available only on type M/T and T/T inverters.
The signal that enables an auxiliary set point can be supplied on any one of the 4 inputs, (for electrical connections,
refer to paragraph 2.3.3).
