Troubleshooting
Locking:
E 01 Flow sensor short-circuit
If the temperature is higher than 125°C the connected flow sensor seems as short-circuit and responds with
a locking. Temperature jumps, which are higher than 50°C/sec, it also occurs locking.
E 02 Locking temperature flow
If the temperature is higher than 100°C by the flow sensor occurs a locking.
E 03 Flow sensor interruption
If the temperature is lower than –20°C the flow sensor seems as disconnected and responds with a lock-
ing.
E 04 Return sensor short-circuit
If the temperature is higher than 125°C the connected return sensor seems as short-circuit and responds
with a locking. Temperature jumps, which are higher than 50°C/sec, it also occurs locking.
E 05 Locking temperature return
If the temperature is higher than 100°C by the return sensor occurs a locking.
E 06 Return sensor interruption
If the temperature is lower than –20°C the return sensor seems as disconnected and responds with a lock-
ing.
E 07 Flue gas sensor short-circuit
If the temperature is higher than 125°C the connected flue gas sensor seems as short-circuit and responds
with a locking. Temperature jumps, which are higher than 50°C/sec, it also occurs locking.
E 08 Flue gas sensor interruption
If the temperature is lower than –20°C the flue gas sensor seems as disconnected and responds with a
locking.
E 09 No flames after ignition
If there is no flame after 4 starts because there wasn‘t any ionisation measurable after the safety time ends,
a locking is occurred.
E 10 Flame stop during a heating demand
A locking will occur, when the ionisation flow sinks more than 3 times under 1.5mA during a single heating
demand.
E 11 Flame message without reason
A locking will occur, when there is a flame without an open gas valve.
