Part’s Function
1
-
The component that measures the inlet and outlet temperature of the
water in the central heating circuit.
Impact in Case of Malfunction
1- It may lead to inconvenience since the temperature set by the user and the
actual temperature will be different.
2- The device does not work.
Main Associated Error Codes
E15, E16, E17, E18, E33, E35, E80, F81
Error Diagnostics and Test
Method
Visual Inspection and Testing:
1
-
Ensure that the cable connections are properly done and undamaged.
2
-
Check for rusting, corrosion, or deformation in the inner part that contacts
the copper pipe.
3-
Measure the resistance.
Maintenance Requirement

Test Method
Resistance Measurement for
The Surface-type NTC
Disconnect the device from power. Remove the supply and return water
surface-type NTCs from the boiler and wait for it to cool at room temperature
for abo ut 10 minutes. Measure the resistance between the NTC ends. Ensure
that the resistance value is appropriate according to the table below.
