3.4 Bottom drain recirculation
3.4.1 Overview
With the installation of a push-pull 3-way valve or any combination of 2-way valves, the water can flow
either over the skimmer, overflow channel or over the bottom drain. This is useful especially for outdoor
pools when the low outside temperature can cool down the water temperature. Energy loss can be
reduced, when the water doesn’t flow over the channel or skimmer. This option can work in 3 scenarios:
Automatic mode – when enabled (see section 0), bottom drain valve will switchover when
the following conditions will apply:
o Pool cover is installed and closed
o Outside temperature is lower than water temperature
Custom timer – when custom timer is defined (see section 0), bottom drain valve can
switchover during defined schedule. This is useful when cover is not installed or in case
the Automatic mode cannot be used.
In combination with pool cover drain – when the bottom drain and pool cover drain (see
3.8.2.3 for details) is enabled, the bottom drain will open when cover will be closed. This
is to ensure circulation on overflow edge pool when the water level is decreased by the
pool cover drain.
NOTE:
This option can be used only with push-pull backwash valve type (read details in section 3.11).
With an installed multi-port (6-way) valve this option cannot be used!
3.4.2 Electrical connection
The device has a powered relay output (230V AC,
50/60 Hz) and enables direct switching of small
loads. This enables to connect push-pull (like
Besgo) or similar valve from any vendor with 230V
coil. Built-in circuit breaker has “LVLØ System” sign
on devices front panel. Example of connecting a
Besgo 3-way valve is on a picture bellow. Connect
terminals of “6 WAY VALVE” output to the valve
using two wires:
CLOSED – (L1) to valve coil phase L
N - to valve coil neutral N
3.4.3 Configuration
Setup of bottom drain option has to be performed via LVLØ mobile application in Service section; select
Basic setup. Relevant settings are:
Bottom drain control: <installed/not installed> Enable or disable the bottom drain feature. The water can

3.5 Filtration
3.5.1 Overview
LVLØ is ready to connect one high-current load filtration pump. Filtration pump output has a failure
monitored motor circuit-breaker combined with contactor with feedback. This provides complete
protection for filtration pump concentrated in a single product.
With LVLØ mobile application, it is easy to set custom timers for filtration pump. Start and stop the pump
several times a day manually or operate in an automatic mode which will activate the pump according to
current pool parameters such as actual temperature or installed technology.
LVLØ is able to operate variable speed pump with up to 4 speeds, where “speed 1” is the fastest and “speed
4” is the slowest pump operation. Thanks to selectable speed profiles, system is able to save enormous
amount of operating costs by running in an automatic mode or in a manual mode, with custom timers for
each speed individually.
3.5.2 Electrical connection
3.5.2.1 Motor circuit-breaker TeSys GV2
LVLØ built in Motor circuit-breaker from Schneider-Electric - TeSys GV2 provides thermal magnetic motor
protection. Breaker is built in LVLØ and fulfills motor control and protection regulations in accordance with
IEC 947-2 and IEC 947-4-1 standard.
The addition of an under voltage trip enables the motor circuit-breaker to be
tripped in case voltage is lost.
Thermal magnetic circuit breakers incorporate both techniques with the
electromagnet responding instantaneously to large surges in current (short
circuits) and the bimetallic strip responding to less extreme but longer-term
over-current conditions. The thermal portion of the circuit breaker provides
an “inverse time” response feature, which trips the circuit breaker sooner for
larger overcurrent but allows smaller overloads to persist for a longer time.
On very large over-currents during a short-circuit, the magnetic element trips
the circuit breaker with no intentional additional delay.
Breaking capacity is 100kA at 230/240/400/415 V AC 50/60 Hz. Rated service short-circuit breaking capacity
(Ics) is 100 % at 230/240/400/415 V AC 50/60 Hz conforming to IEC 60947-2.

Please check vendor specification of filtration pump connected to LVLØ
and adjust rated current of the motor circuit-breaker (see picture).
3.5.2.2 3Pole contactor iCT
iACT Schneider-Electric contactor used in LVLØ is electrically controlled switch
used for direct switching of power circuit. Contactors used are compliant with
EN 61095 and CEI 1095 standards.
Unlike general-purpose relays, contactor for filtration pump in LVLØ is designed
to be directly connected to high-current load devices. Continuous safety for
operators by unqualified personnel is allowed because of Class-2 insulation.
Contactors in provide state indication, interference filtering and dual control
– manual and remote.
Electrical endurance of used iACT contactors is 100,000 cycles (O-C).
Contactor remote and manual operation options:
NOTE:
Remote control of contactors will override manual ON switching (remote off will turn off when
contactor switched on manually) if the contactor is not locked in I+P position.

3.6 Flow switch
3.6.1 Overview
Flow switches have wide application in swimming pool engineering. Flow switches are used to ensure that
adequate flow exists and provide proof of proper water circulation before heaters, dosing and other
devices are turned on.

Optical: Overflow edge pool
Optical Water Level Sensor terminal
BLK – flow switch BLU– flow switch
Ultrasonic: Skimmer pool
5V/3A terminal:
+5V – flow switch
Ultrasonic Level Sensor terminal:
0-10V – flow switch
In LVLØ the switch is used to give a signal to shut off the filtration pump and trigger an alert, in case of no
flow signal within 2 minutes after turning on the filtration pump. This will shut down all critical processes
like chemistry dosing, heating, backwash, etc., to avoid further damage on swimming pool equipment.
3.6.2 Electrical connection
Any flow switch with potential free digital output (On/Off) can be implemented within LVLØ hassle free
technology. Unused terminals of water level sensors can be used. Connection diagram for overflow edge
and skimmer pool is shown on pictures bellow:
3.6.3 Configuration
Flow switch setup has to be performed via LVLØ mobile application in Service section; select Filtration.
Flow switch: <not installed/optical/ultrasonic> Select proper flow switch configuration based on installation
type.
After performing setup or any changes to this section, click „SAVE SETTINGS” to save configuration to system.
3.7 AUX – Two auxiliary outputs
3.7.1 Overview
Countercurrent for everyday swimming, bubble feature for relaxing and revitalizing the muscles, waterfalls
for shoulder and neck massage; these and other unique water attractions improve general wellbeing,
reduce stress, turn a swimming pool into effective fitness feature and provide overall relax and fun.
LVLØ is ready to connect two independent high-current loads as it is equipped with two auxiliary outputs.
These outputs have motor circuit-breakers combined with contactor. This provides complete protection
for motors concentrated in a single product.

In addition, these two outputs can be safely switched from swimming pool via build in pneumatic switches
or with any pushbutton connected to “SWITCH AUX 1 & 2” inputs. Details in 3.7.4
3.7.2 Electrical connection
3.7.2.1 Motor circuit-breaker TeSys GV2
In LVLØ built in Motor circuit-breaker from Schneider-Electric - TeSys GV2 provide thermal magnetic motor
protection. Breakers are built in LVLØ and fulfill motor control and protection regulations in accordance
with IEC 947-2 and IEC 947-4-1 standard.
The addition of an under voltage trip enables the motor circuit-breaker to be
tripped if voltage is lost.
Thermal magnetic circuit breakers incorporate both techniques with the
electromagnet responding instantaneously to large surges in current (short
circuits) and the bimetallic strip responding to less extreme but longer-term
over-current conditions. The thermal portion of the circuit breaker provides
an “inverse time” response feature, which trips the circuit breaker sooner for
larger overcurrent but allows smaller overloads to persist for a longer time.
On very large over-currents during a short-circuit, the magnetic element trips
the circuit breaker with no intentional additional delay.
Breaking capacity is 100kA at 230/240/400/415 V AC 50/60 Hz. Rated service short-circuit breaking capacity
(Ics) is 100 % at 230/240/400/415 V AC 50/60 Hz conforming to IEC 60947-2.
IMPORTANT:
Thermal Adjustment. Motor circuit-breaker TeSys GV2 has a wide
thermal adjustment range. The rated current 'Ir' is continuously
adjustable from ~60% to 100% of its nominal current 'In'.
Please check vendor specification of device connected to LVLØ and adjust
rated current of the motor circuit-breaker (see picture) for Filtration,
AUX1 and AUX2 output.
3.7.2.2 3Pole Contactor iCT
iACT Schneider-Electric contactor used in LVLØ is electrically controlled switch
used for direct switching of power circuit. Contactors used are compliant with
EN 61095 and CEI 1095 standards.
Unlike general-purpose relays, contactors in LVLØ are designed to be directly
connected to high-current load devices connected to AUX 1 and AUX 2
connector. Continuous safety for operators by unqualified personnel is
allowed because of Class-2 insulation. Contactors in provide state indication,
interference filtering and dual control – manual and remote.
Electrical endurance of used iACT contactors is 100,000 cycles (O-C).
