1 Filtration modes.
2 Manual: Allows the ltration process to be turned on
and off manually.
3 Filter cleaning: This mode is used to backwash the
lter.
4 Automatic: In this mode, ltration is turned on
according to the start and end times set in the time
slots. The time slots always operate on a daily basis.
5 Smart*: This mode is based on the automatic mode,
with its three ltration intervals, but the ltration times
are adjusted according to the temperature. This is
done by setting two temperature parameters: the
maximum temperature, above which the ltration
times will be determined by the time slots, and the
minimum temperature, below which ltration will be
reduced to ve minutes, the minimum operation period.
Between these two temperatures, the ltration times
will be staggered linearly. The antifreeze mode can be
activated to turn the ltration on if the water temperature
falls below 2°C.
6 Heating : This mode acts in the same way as the
automatic mode, but it can also operate via a relay that
controls the temperature. The set point temperature is
determined in this menu and the system operates with
a hysteresis of one degree (for example: if the set point
temperature is 23°C, the system will start up when the
temperature falls below 22°C and shut down only when
it rises above 23°C).
Heating control OFF: The heating operates only during
the ltration periods congured.
Heating control ON: Keeps the ltration on after
the ltration period has expired if the temperature is
below the set point temperature. When the setpoint
temperature is reached, the ltration and heating stop
and only resume when the next programming period
begins.
7 Intelligent*: In this mode, the user has two operating
parameters: Select the required water temperature
and the minimum ltration time (minimum two hours
and maximum 24 hours). The ltration will operate
for at least ten minutes every two hours to check the
temperature. The minimum ltration time selected is
divided into twelve sections that are added to its ten
minutes. Example 1: Over twelve hours, the time
is divided between the twelve times a day when the
ltration starts up to check the temperature.
Example 2: (12 hours x 60 minutes) / 12 = 60 minutes
every two hours. This is the ltration and heating
period every two hours. If the programmed ltration
period ends and the required temperature has not
been reached, the ltration and heating remain on until
the required temperature is reached. To minimize the
number of hours during which ltration operates each
day, this additional time will be deducted from the next
ltration periods occurring during the rest of the day.
