7.4.4. Booster set with random starts
To activate the mode booster set with random starts
(which consists of the single pump behavior with the
addition of a random delay both when the pump is
turned on and off) just follow the procedure.
1. Operation to be done for each pump:
1.1 Turn on the pump and set it in STOP
1.2 Access the GP menu
1.3 Set GP01=1
The settings of the stop pressure and restart pressure
remain enabled by parameters UP01 and UP02 as for
normal single pump mode.
For a correct booster set mode operation UP01 must
be the same for both pumps, also UP02 must be the
same for both pumps.
7.5. Operating mode
The booster set mode provides a random delay in
switching on (0-5s) and a random delay of the timing of
the turned off attempt (0-10s). The AP06 parameter is
the pressure drop which all taps are considered closed
and so the pump switched off.
The AP07 parameter allows to regulate the switch off
attempt.
7.5.1. Warning for high number of starts/hour
The TANK symbol
will light on, due to a warning
for high number of starts and stops, if the pump
achieves at least 20 starts in a short time (cycle time
less than 5 seconds).
Press (enter) button to reset the warning.
If the pump starts more than 150 times in 1 hour, Er05
will be displayed.
7.5.2. Dry-run settings operation and management
In case of pump not primed and without water inside
the pump casing:
UP03=0 (default)
In normal operation conditions, i.e. after the first
starting (15s), the warning Er01 is displayed so the
pump will try to start again every 10 minutes for 5
seconds for maximum 5 times.
In the case that all these attempts fail, Er01 is kept
displayed and a manual reset or turn off and back on
the pump is required.
UP03=1
Alternative operation mode, i.e. after the first attempt
(15s), Er01 is displayed and the pump will try to start
again every 10 minutes for 5 seconds, after that the
pump will try to start again every 24h for 5s (there’s
no limit of attempts in this case). However, it is still
possible to manually reset or restart the pump.
Obviously, manual reset is possible even by switching
the pump off and back on.
In case of pump not primed with water inside the pump
casing.
The first priming attempt lasts 120s and the next ones
last for 30s for maximum 5 times.
If UP03=1 the attempts continue every 24h lasting 30s.
