General warning

The product cannot be used by people (including children) with reduced physical, mental or sensory capabilities or inexperienced persons unless they received, through a delegated responsible person, surveillance or a training or proper instruction about the product.
Each operation for installation and/or maintenance on OMNIBUS 360 controllers must be executed by qualified personnel only. EURAPO refuses every responsibility for damages caused by incorrect installation or tampering or improper use of the controller.
For safety reasons, during installation, maintenance or repairing phase the following instructions must be observed:

  • always wear work gloves;
  • do not expose the electronic board to flammable gas;
  • do not install the console in areas with risks of explosion or corrosion, in moist rooms, in open air or severely dusty air.

Before proceeding with any installation and/or maintenance operation or before removing any protection device, make sure that the electronic board has been disconnected from the power supply.
Electrical connections must respect the safety norms and rules of the Country where the product is installed. Always ground the unit.
Do not twist, remove or pull the electrical cables connected to the electronic board, even if it is not connected to the power supply.
Make sure the electrical system can provide the necessary operating current for the normal use of the electronic board in addition to the other electronic devices already present in the same system.
Do not remove the safety labels on the product. If not readable, ask for replacement. It is very dangerous to touch the electronic board with wet parts of the body or barefoot. No water sprays should reach the electronic board.

DESCRIPTION

The remote ROUND DISPLAY Console of OMNIBUS 360 is designed for controlling water terminal units (fan coil units, cassettes, high pressure ducted units) for air conditioning and heating applications in domestic, residential or public buildings.

It is composed by an electronic board located in a plastic casing, LCD screen, touch buttons and one NTC integrated air sensor. A buzzer can acknowledge the correct receipt of all commands.

It is designed for wall installation and it has to be connected to the OPower card (installed on the water terminal unit) with 4 wires, for power supply and data exchange.
