The HyBo (Hydraulic Interface Unit) is a hydraulic interface installed in multi-family dwellings between the centralized systems and each flat. It allows combining the efficiency of a centralized boiler with the benefits of individual control and metering.

The Metering Box is designed to be applied in central heating systems for multi family dwellings where the domestic hot water production is centralized. The typical functions performed by the Metering Box are the following:

• Guarantee heat and water metering accuracy for each individual flat, with the optional possibility of connecting signals with a pulse or M-bus system for cetral reading
• Facilitate balancing by allowing a balancing device at each flat level. Balancing can be static or dynamic with differential pressure control
• Collect balancing and metering components in a single box, easier to install and control
• The Metering Box is delivered with predisposition for installation on site of the specific project required components for balancing and metering (list of suggested Honeywell components is described in this datasheet). Components not included with the unit, must be ordered separately. Before installing components, the installer can perform a system cleansing and flushing to avoid fouling of the Unit with impurities or debris from the pipe work installation procedures.

The Metering Box unit can provide the following main functions:

• Heat and water Direct reading/Pulse/M-Bus metering system
• Balancing: the unit can be equipped with a Honeywell Kombi-3-plus (static balancing) or Honeywell Kombi-3-plus and diaphragm (automatic balancing with differential pressure control) in order to provide the right commissioning of the heating system
• Heating system control: the unit is equipped with a motorised valve that receives a command from an external thermostat (optional) will allow to open or close the heating circuits
