7.4.3. GP – Booster sets settings
Par. Description
GP01 Mode
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) follow the procedure.
1. Operation to be performed for each pump:
1.1 Turn on the pump and set it to 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 correct booster set mode operation UP01 must be
the same for both pumps, also UP02 must be the same
for both pumps.
Booster set mode provides a random delay in switching
on (0-5s) and a random delay with respect to the timing
of the switch-off attempt (0-10s).
If using booster set mode, check the Mèta booster
set instruction manual available on the website www.

7.5. Operating modes
The operating mode allows you to keep the system
pressure constant at a setpoint value adjustable
with the UP01 parameter. The restart pressure
can be calculated by subtracting UP01 – UP02, the
latter defined as pressure
is equipped with a membrane
expansion vessel.
The AP06 parameter is the pressure drop at which

off attempt.
7.5.1. Warning for high number of starts/hour
The TANK symbol
for a 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) 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 management
In case of pump not primed and without water inside
the pump casing:
UP03=0 (default)
In normal operating conditions, i.e. after the first start
(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 until the error is reset or the pump is switched
off and back on again.
UP03=1
Alternative management, 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 is
no limit of attempts in this case). However, it is still
