Metering Box METERING AND AMBIENT HEATING FOR HEATING SYSTEM Overview PRODUCT DATA The Honeywell Substations series consist of the following products: Metering Box (this datasheet) Heat Interface Unit, with instant domestic hot water production (see separate datasheet) To fullfil the plant requirements several options are available for each product range. Fig. 1. Unit as delivered, with blind pipes Application 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 central 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. Fig. 2.
