Cause and Remedy:
[5013] PE Underpressure box SC
Negative draft input short-circuit, measuring circuit from negative draft mea-
surement is shorted out – Input UP
Signal incorrect
Signal cable defect
Signal too high
[5041] [5042] PE Low underpressure
Negative draft pressure in boiler is not achieved [5041] or is too high [5042] –
Exit LUFT (SMART + Condens) / Output SZ (PE+PEK)
Negative draft tube
disconnected
Negative draft does not
change
Negative draft pressure
too low
Negative draft pressure
too high
[5014] / [5016] PE Analog input 1/2 BS
Analog input 1/ 2 sensor fracture, measuring circuit of Analog input sensor
open – Output AE1 / AE2
Signal incorrect
Signal cable defect
Level detection system ac-
tivated (valid for AE2)
[5015] / [5017] PE Analog input 1 /2 SC
Analog input 1 / 2 sensor short circuit, measuring circuit of Analog input sen-
sor is shorted out – Input AE1/AE2
Signal incorrect
Signal cable defect
Signal too high
Check poarity and signal (0-10V)
Replace sensor
Signal above 10V
Connect up negative draft tube
Check negative draft tube for leaks.
Check flue gas tube for blockage.
Close boiler door, check tube to negative
draft sensor, check whether boiler flue gas
outlet is clear, check whether condensation
heat exchanger is clear. Make sure flue gas
fan is running.
Check induced draft blower
Check poarity and signal (0-10V)
Replace sensor
Check settings
Check poarity and signal (0-10V)
Replace sensor
Signal above 10V
