Part’s Function
1- The component that transfers the heat from the hot water from the main heat exchanger
to the domestic water installation in order to meet domestic water demands.
2- The water circulation is maintained through this componen (internal by-pass) when all
radiator valves are closed.
Impact in Case of Malfunction
1- In case of partial or complete blockage, domestic water does not heat up or continuously
overheats.
2- The central heating circuit overheats as the internal by-pass function does not work.
3- The pressure in the central heating system constantly increases (the domestic water
enters the central heating circuit due to puncture in the plate heat exchanger).
Main Associated Error Codes
E03, F07, E16, E17,E80, F40
Error Diagnostics and Test Method
1- Visually inspect for leakage from the plate heat exchanger to the external environment.
2- Check whether the central heating circuit pressure changes excessively by turning on the
domestic water.
Maintenance Requirement
