F50
Boiler Sensor
Error
The boiler
sensor may be
defective.
1- Make sure that the boiler is installed with boiler system and that the P00 parameter is set to 3 or 4.
2- Check the connection and conductivity of the boiler 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.
F51
PT1000 solar sensor
error
PT1000 solar
sensor may be
defective.
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.
F52
Domestic water
temperature
sensor error
The water
temperature
sensor may be
defective.
1- Check the connection and conductivity of the DHW sensor cables. If there is a problem, replace the
cables.
2- Check the resistance of the sensor by measuring it. If there is a problem, replace the sensor.
3- If the problem is not resolved, replace the mainboard.
F53
Flue gas
temperature sensor
error
Flue gas
temperature
sensor short or
open circuit
1- Check the connection and conductivity of the flue gas sensor cables. If there is a problem, replace
the cables.
2- Check the resistance of the sensor by measuring it. If there is a problem, replace the sensor.
3- If the problem is not resolved, replace the mainboard.
F81
Waiting for
temperature
sensor deviation
test
Temperature sensors
may be defective.
1- Turn off the power and wait 5 minutes. Turn on the power again and ensure that the error does not appear on
the display.
2- Check the connection and conductivity of the supply/return or DHW sensor cables. If there is a problem,
replace the cables.
3- Check the resistance of the sensors by measuring it. If there is a problem, replace the sensor.
4- If the problem is not resolved, replace the mainboard.
F201
Mainboard -
MMI card
communication error
There may be a
problem with
the card or
cable
1- Check the ports on both sides of the MMI cable (mainboard and MMI card). If there is a
problem, replace the MMI cable.
2- If the problem persists, replace the MMI card.
PREDICTIVE MAINTENANCE WARNINGS
1
Risk of flame loss
Predicts the flame loss risk of the device.
1- Check the electrode position and the electrode
cable.
2- Replace the electrode if necessary.
3- If the error repeats within a short period (<1
year), replace the mainboard.
2
Risk of high water
pressure
Predicts the safety valve activation of the device.
above 2.5 bar this warning will appear.
if the water pressure increases
1- Ensure the user fills the boiler with water up to
the pressure range of 1-1.5 bar.
2- If the water filling pressure range is correct,
check the expansion tank pressure and replace
it if necessary.
3
Risk of low water
pressure
There may be water leakage. If the boiler is plugged in electricity for the last 24
hours and gives F37 error within a week, this warning will appear.
1- The water leakage may be caused by the boiler
or the installation. If there is no water leakage from
the boiler, inform the user that the installation
should be inspected.
