2. Exchange to standby: when the pump is on standby but 50% of the
ET time has been exceeded
If ET has been set at 0 there will be exchange to standby. Whenever
a pump in the set stops, a different pump will start first next time it is
restarted.
If the parameter ET (Max. switching time) is set at 0, there will
be exchange at each restart, irrespective of the pump's actual
work time.
7.6.12 - AY: Anti Cycling
As described in paragraph 9, this function is for avoiding frequent switch-
ing on and off in the case of leaks in the system. The function can be
enabled in 2 different modes, normal and smart. In normal mode the elec-
tronic control blocks the motor after N identical start/stop cycles. In smart
mode it acts on the parameter RP to reduce the negative effects due to
leaks. If set on "Disable", the function does not intervene.
7.6.13 - AE: Enabling the anti-block function
This function is for avoiding mechanical blocks in the case of long inactiv-
ity; it acts by periodically rotating the pump.
When the function is enabled, every 23 hours the pump performs an
unblocking cycle lasting 1 min.
7.6.14 - AF: Enabling the anti-freeze function
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.
7.6.15 - Setup of the auxiliary digitali inputs IN1, IN2, IN3, IN4
This paragraph shows the functions and possible configurations of the
inputs of the control unit, connected by wireless to the device, by means
of the parameters I1, I2, I3, I4. For the electrical connections refer to the
control unit manual.
The inputs IN1..IN4 are all the same and all the functions can be associ-
ated with each of them. Parameters I1, I2, I3 and I4 are used to associate
the function required to the corresponding input (IN1, IN2, IN3 and IN4.).

Each function associated with the inputs is explained in greater detail
below in this paragraph. Table 15 sums up the functions and the various
configurations.
The factory configurations can be seen in Table 14.
