Kessel Typ VSL-160-B

Störungscode L17

Ursach:

The temperature difference between the U1 and U6 sensors is too great

LÖsung:

- If one or both sensors does not have the correct resistance value, it must be replaced.
-If temperature difference between U1 and U8 is higher than 55°F at maximum input, the heating water flow rate is too low. The heating water flow rate must be corrected.
