Error code output on combination timer or control element
If the system is fitted with a combination timer, when an error occurs an error
code is displayed on the timer's screen until the heater has been properly
repaired.
The error code is output if the heater is fitted with a control element after an
error has occurred by the switch- on indicator/error code indicator flashing.
After a burst of fast flashes the error code will be displayed by a se- quence of
long flashes, the number of which is shown in the table below.
