6 - HISTORY
In this submenu, merely informative, record is shown of the latest alarms, if any, due to motor current, or detection that
the pump is running dry. If there is more than one, modify the viewing by pressing .
The information is presented in the following format:
XX-DD/MM/YY-##
Where:
XX = type of alert (OL for overcurrent, DR for running dry)
DD/MM/YY = Day/Month/Year of alert
## = Number of alert on the same day
7 - MAINTENANCE
The time controller can advise when cleaning the basket in the pump is recommended as well as when it is recommen-
ded to clean the sand filter.
The alerts, if they are active, simply show a message on the screen, which can be reset.
Warnings can be adjusted individually, indicating how frequently, in days, we want to be warned regarding the cleaning
of the basket or filter, as the case may be. If they are active, they will simply show a message on the screen accompanied
by a blinking light "ALARM". These warnings are only informative, with the aim of helping us to carry out the general
maintenance tasks of the filtration system.
We will also find the function "SKIMMING", disabled by default, which allows us to select how frequently, in hours, the
pump will be activated for a few minutes. The operating time once these hours have been completed is 3 minutes. When
this time has passed, the programmed hours will be counted once again and the pump will be activated for 3 minutes,
and so on. This function is very useful in swimming pools where waste often falls onto the surface of the water, such as
leaves from trees, insects, etc...
8 - METERS
Informative screens that show the total count of partial operating hours (press to reset), and also a totaliser of
F2
the pump's general operating hours (not resettable).
Press to select the total or partial viewing of the pump's operating hours.
9 - INTAKE/OUTPUT
The external intake as well as the relay output can be activated in this submenu (deactivated by default). Press to
F2
activate/deactivate.
If the external intake is enabled, the pump will automatically start if active contact is detected, and will deactivate when
contact is deactivated. Activation by active contact depends on programming in section "3. FILTRATION". Deactivation
by deactivated contact takes into account the programming in section "3. FILTRATION" to decide whether the pump is
in a programmed filtering cycle or not.
This intake also enables the remote activation/deactivation of the pump through a PT-100 type temperature probe.
In this case, the system decides, depending on the temperature recorded by the censor, the activation and deactivation
time of the pump, from running for 1 minute and stopped for 59 minutes at +3ºC up to a maximum of 55 minutes
running per 5 minutes stopped at very low temperatures (-30ºC). In this extreme range of temperatures, activation and
