It will also be possible to set the alarm levels for maximum and minimum level. The minimum settable level (including the minimum alarm level)
cannot be lower than 15 cm. The maximum settable level (including the maximum alarm level) cannot be higher than the tank height minus 5 cm.
The various levels are separated from one another by a minimum of 5 cm.

Operation with depth sensor without display

In operation with a depth sensor, the parameters must be set with the Trimmers SP and DP, see Figure 42.
SP represents the maximum level in the tank (L
•
DP represents the minimum level in the tank (L
•
percentage of SP.
If the level in the tank is the same as or higher than SP, the pump P1 is started and, if the level continues to rise, pump P2 is also started after a
delay of 4 seconds.
When level DP is reached, both pumps stop.
The following table sums up the behaviour described:

P2 Pump P1 = started for at least 4 seconds and tank => SP

KIWA PRESSURE BOOSTING FUNCTION

The E.box panel can be used for making a system to increase water pressure that respects the KIWA standard. This mode is available only if the
language chosen is French, Dutch or English. As control inputs, either pressure switches on a pressure sensor can be used. A pressure switch
for low pressure must be used to put at the intake of the set.
8.1

Expansion vessel

In KIWA pressure boosting it is necessary to use an expansion vessel of at least 19 litres per pump.
8.2

Electrical connections of pump and supply

Connect the supply line and the pumps as described in chapter 2.1.
8.3

Connection of additional protections: high pressure and motor thermal protection

It is possible, but not necessary, to use the alarm inputs to the E.box so that the pumps stop in the case of pressure that is too high or too high
motor temperature. In the case of an alarm, the pumps stop, the alarm leds blink, the corresponding alarm outputs are activated. If the display is
present, the type of alarm is indicated. When the alarm conditions no longer exist, the E.box resumes normal operation.
