4 051 052 053 056 060 061 26 Troubleshooting Error code Fault description Display Time exceeded – blowing cold Safety time exceeded Flame aborted from control stage “large” Flame aborted from control stage “small” Temperature sensor – interruption Please note The test with a bridge in the 14-pole connector can only be performed if HYDRONIC is still installed in the vehicle or if a test facility is available. Temperature sensor – short-circuit, overload or accidental ground Please note The test with a bridge in the 14-pole connector can only be performed if HYDRONIC is still installed in the vehicle or if a test facility is available. Explanations Remedies At start, flame sensor reports temperature > 70°C for longer than 240°C. Check exhaust and combustion air guidance. Check flame sensor – control values see page 34. Check exhaust and combustion air guidance. Check fuel quantity and fuel supply, see page 41. Clean or replace filter in dosing pump connection. Warning After flame aborted from control stage “large” or “small” and after starting attempt within allowed number, HYDRONIC proceeds with a new start, where applicable with subsequent start repeat. If the new start or start repeat is successful, the error code is deleted. Error (because no more starting attempts allowed) Check exhaust and combustion air guidance. Check fuel quantity and fuel supply, see page 41. Check flame sensor, see error code 064 and 065. Remove controller and check connection lead of temperature sensor for any signs of damage. If the lead is OK, then short the temperature sensor: route the cable in the 14-pole connector from chamber 3 to chamber 4. Switch HYDRONIC on: – If error code 061 appears, then remove and check temperature sensor, see page 38. – If error code 060 still appears, then check and if necessary replace controller. Remove controller and check connection lead of temperature sensor for any signs of damage. If the lead is OK, then remove the 14-pole connector from controller, unclip cable 0.5 2 blue from chamber 3 and cable 0.5 2 blue from chamber 4. Connect 14-pole connector to controller and switch HYDRONIC on. – If error code 061 appears, then remove and check temperature sensor, see page 38. – If error code 061 appears, then check and if necessary replace controller.

Flame sensor – short-circuit, overload or accidental ground Please note The test with a bridge in the 14-pole connector can only be performed if HYDRONIC is still installed in the vehicle or if a test facility is available. Overheating sensor – interruption Please note The test with a bridge in the 14-pole connector can only be performed if HYDRONIC is still installed in the vehicle or if a test facility is available. Overheating sensor – short-circuit, overload or accidental ground Please note The test with a bridge in the 14-pole connector can only be performed if HYDRONIC is still installed in the vehicle or if a test facility is available. Controller defect External interference voltage Explanations Remedies Remove controller and check connection lead of flame sensor for any signs of damage. If the lead is OK, then short the flame sensor: route the cable in the 14-pole connector from chamber 1 to chamber 2. Switch HYDRONIC on: – If error code 065 appears, then remove and check flame sensor, see page 34. – If error code 064 still appears, then check and if necessary replace controller. Remove controller and check connection lead of flame sensor for any signs of damage. If the lead is OK, then remove the 14-pole connector from controller, unclip cable 0.5 2 blue from chamber 1 and cable 0.5 2 brown from chamber 2. Connect 14-pole connector to controller and switch HYDRONIC on. – If error code 064 appears, then remove and check flame sensor, see page 34. – If error code 065 appears, then check and if necessary replace controller. Remove controller and check connection lead of overheating sensor for any signs of damage. If the lead is OK, then short the overheating sensor: route the cable in the 14-pole connector from chamber 5 to chamber 6. Switch HYDRONIC on: – If error code 072 appears, then remove and check overheating sensor, see page 38. – If error code 071 still appears, then check and if necessary replace controller. Remove controller and check connection lead of overheating sensor for any signs of damage. If the lead is OK, then remove the 14-pole connector from controller, unclip cable 0.5 2 red from chamber 5 and cable 0.5 2 red from chamber 6. Connect 14-pole connector to controller and switch HYDRONIC on. – If error code 071appears, then remove and check overheating sensor, see page 38. – If error code 072appears, then check and if necessary replace controller. Replace controller. Error in controller from interference voltage from vehicle network, possible causes: poor batteries, poor battery chargers, other interference sources; eliminate interference voltages. 27
