FLOW TURBINE
Subject
Description
Part Function
In case of tap water demand, its turbine structure starts rotating to form
the magnetic field that flow sensor will detect.
Impact in Case of
Faulty Operation
Boiler can not detect tap water demand; even if there is any DHW water
demand, it always runs in the central heating mode.

Error Codes

Troubleshooting and
Testing Method
Visual Inspection and Testing:
1- Checking whether there is any deformation, crack, fissure, etc. on flow
turbine blades
2- Filter cleaning and flow sensor inspection
Note: If P00 parameter is "5", the boiler does not operate with the tap
water since it will be only in the central heating mode.
Maintenance Period
Once a year, according to instructions given above.
3 WAY SHAFT GROUP
Subject
Description
Part Function
1- It is the group getting its motion from 3-way motorized valve in order to
ensure that boiler goes in the summer mode and the winter mode.
2- It ensures the internal by-pass function when the central heating valves
are closed.
Impact in Case of
Faulty Operation
1- Boiler may remain constantly in the summer or winter mode in case the
valves are jammed.
2- Internal by-pass function may not be functional.
3- There may be water leakage at 3-way motorized valve connections.
Primary Relevant
Error Codes
E03, F07
Troubleshooting
andTesting Method
1- Set and operate the boiler in the winter mode. Check whether there is
any temperature increase on CH return temperature sensor.
2- Set and operate the boiler in the summer mode. Check whether there is
any temperature increase on immersion type temperature sensor. When
boiler operates in the summer mode, no heating should be on the radiator
core located to the closest to boiler. Check it.
3- Remove three-way motorized valve and check whether there is any
water at the bottom.
