Control 1.3 Swimming Pool Control Unit
Operation

The Forced Overflow Channel submenu is only available if an overflow pool has been set as the pool type
( Treatment

Level Control

Pool Type ). The filter pump continues to run at normal speed for
the set time (max. 200 min) after backwashing, regardless of the switching times.
6.4.3.3 Pump Type (Setting)
You need to go to the Treatment

Pump Type submenu to set the pump type used. Here the user can
choose between the following pump types:

Single-phase: corresponds to a 230 V pump

Three-phase: corresponds to a 400 V pump

Frequency converter: the pump is controlled by a frequency converter and can therefore be
operated at different speeds

Contactor: pump is connected to an external contactor that is activated by the control unit
The power supply lines of the single-phase pump, the three-phase pump or the external contactor must be
connected to the terminals A1. If a frequency converter is used, the pump must be supplied externally with
continuous voltage. Only the control lines are then connected to the control unit. The following terminals are
available for connection of the control lines:

A13 (speed 2-normal, potential-free N/O contact)

A14 (speed 3-increased, potential-free N/O contact)

A15 (speed 1-slow, potential-free N/O contact)

A16 (stop signal, potential-free switch)

A18 (percentage speed, standard signal 0-10 V)
6.4.3.4 Frequency Converter Settings
The Frequency Converter Settings
submenu is only available if “Frequency converter” has been set as
the pump type
(
Treatment

Pump Type ).
You need to go to the Treatment

Frequency Converter
Settings submenu to set the frequency converter used. This is shown in
Figure 5. The user can set the following frequency converter parameters:

Frequency converter type: if an external frequency converter (external) or a pump with an integrated
frequency converter is used. If the pump has an integrated frequency converter, you can choose
between a frequency converter with or without a stop signal. The potential-free terminals can be
switched in different logic depending on the setting. This can be found in table 2.

Fault signal: defines whether the fault signal of the frequency converter works as an N/C or NO
contact.

Speed X: the corresponding speeds can be specified in percentage values if the integrated
frequency converter is controlled by means of a standard signal (0-10 V). The values entered here
are also displayed in the remote portal.
