ERROR CODE: F51
ERROR TYPE: PT1000 solar sensor error
PROBABLE CAUSE: PT1000 solar sensor may be defective.
SOLUTION:
1- Ensure that the P00 parameter is set to 2 or 4 because the boiler is installed with the solar system.
2- Check the connection and conductivity of the PT1000 sensor cables. If there is a problem, replace the cables.
3- Check the resistance of the sensor by measuring it. If there is a problem, replace the sensor.
4- If the problem is not resolved, replace the mainboard.
