1Safety information
1.1 Safety instructions
Electrical equipment may only be installed and fitted by electrically skilled persons. The country specific
regulations and the valid guidelines must be followed.
Failure to observe the instructions may cause damage to the device and result in fire and other hazards.
Do not connect any external voltage to the inputs. Doing so may damage the device(s).
Danger of electric shock. Before working on the device or before exchanging any connected equipment
(sensors, pumps, motors, lights, etc.), disconnect mains voltage and switch off circuit breakers.
Vibrations during transport can loosen the outputs. Voltage may be present at the outputs when the mains
voltage is connected to the system.
1.2 Information for electrically skilled persons
DANGER!
Electrical shock when live parts are touched. Electrical shock can be fatal.
Before working on the device, disconnect the power supply and cover up live parts in the working
environment.

1.3 Notice
This document should be read in conjunction with the accompanying notice and the relevant sections of
other applicable guidance documents.
We recommend performing setup step by step from top to bottom of the application.
In application it is necessary to always confirm by saving settings.
It is necessary to confirm by saving settings also all parts of technologies, which are not installed.
It is necessary to perform complete setup correctly to ensure that LVLØ controller will work as expected.

2Overview
2.1 LVLØ – Ultimate Pool Controller
LVLØ – Ultimate pool controller is compact all-in-one solution, which fulfills requirements of majority pool
installations. LVLØ supports both skimmer pool and overflow edge pool with any water treatment
technology. LVLØ is independent of pool equipment vendors and chemical suppliers. It fits with all water
treatment techniques using either –chlorine, salt water or fresh water systems and supports the chemistry
changeover, e.g. from chlorine to salt water without the need to replace the controller. It can directly
operate up to four standard dosing pumps from any vendor or any size. Simply select your choice and adjust
parameters in the application.
