GE556-6 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 the 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 circuit and reducing the return temperature. The various parameters can be set via a remote control which also performs the function of a programmable chronothermostat.
