* Function available for firmware V 26.1.0 and later versions
6.6.13.1
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.
6.6.13.2
Setting the external float function
The external float can be connected to any input, for all electrical connections, refer to paragraph 2.2.4.2. The float function is
implemented by setting the parameter INx associated with the input where the float is connected, with one of the values of Table 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.

6.6.13.3
Setting the auxiliary pressure input function
The auxiliary set points are disabled if the flow sensor is not used (FI=0) and when FZ is used in minimum frequency mode
(FZ ≠ 0).
The signal that enables an auxiliary set point can be supplied on any one of the 4 inputs, (for electrical connections, refer to paragraph
2.2.4.2). The auxiliary set point function is obtained by setting parameter INx, associated with the input on which the connection is
made, in accordance with Table 24.
The auxiliary pressure function modifies the system setpoint from pressure SP (see section 6.3) to pressure Pi . For electrical
connections, see paragraph 2.2.4.2) where i represents the input used. In this way, as well as SP there are four additional pressures
available: P1, P2, P3, and P4.
When this function is enabled, the symbol Pi is shown on the STATUS line of the main page.
The input must be active for at least 1 second for the system to operate with the auxiliary setpoint.
When operating with the auxiliary setpoint, the input must not be active for at least 1 second to return to operation with setpoint SP.
The function behaviour is summarised in Table 24.
