Part’s Function
When there is a domestic water demand, the turbine starts to turn and creates the magnetic
field that the flow sensor detects.
Impact in Case
of Malfunction
1-
The device cannot receive the domestic water demands and works in the central heating
state even if there is a domestic water demand.
Main Associated Error Codes
Error Diagnostics-Test Method
and Maintenance
Visual Inspection and Testing:
1- Check the fins of the flow turbine for deformation, fractures, cracks, etc.
2- Check if the filter is clean and inspect the flow sensor.
Note: If the P00 parameter is set to "5", the device will only work in central heating mode,
and will not work in the
domestic water mode.

Description
Part’s Function
1- The assembly that receives movement from the 3-way motorized valve in order to enable
the boiler to switch between the summer mode and the winter mode.
2- It performs the internal by-pass function if the central heating circuit valves are closed.
Impact in Case of Malfunction
1- If the assembly hangs up/jams, the boiler may remain in the summer mode or the winter
mode con tinuously.
2- The internal by -pass feature may not function.
3- There may be water leakage from the three-way motorized valve connection.
Main Associated Error Codes
E03, F07
Error Diagnostics and Test
Method
Visual Inspection and Testing:
1- Run the boiler in winter mode. Check if there is a temperature increase in the supply water
temperature sensor.
2- Run the boiler in summer mode. Check if there is a temperature increase in the
immersion-type temperature sensor. When the boiler is running in the summer mode, the
radiator core which is closest to the boiler should not heat up. Ensure this does not happen.
3- Remove the 3-way motorized valve and check if there is water at the bottom.
