GE556Y413/416 heat interface
unit with electronic regulation,
double heat exchanger and
adjustable tail pieces
The GE556Y413 and GE556Y416 heat interface units (HIU) allow the metering of heat energy consumption for heating and
the production of DHW (Domestic Hot Water) in modern autonomous systems with centralised heat production (e.g. district
heating).
The configuration with two heat exchangers in parallel provides the following advantages:
• parallel and non-intermittent handling of the domestic hot water and heating functions;
• higher safety, the heating circuit is a sealed pressurised system should there be any leaks within property only a small
amount of water will be discharged.
The management of the HIUs parameters is completely electronic.
This allows significant energy savings, minimizing the flow demand from the primary side and reducing the return temperature.
The various parameters can be set via remote control which also performs the function of programmable chronothermostat.
