CONTROL BOX RESET

To reset the control box, proceed as follows:
Press and hold the reset button for between 1 and 2 seconds. If the burner does not restart, you must
®
make sure the limit thermostat ( TL ) is closed.
If the control box reset button continues to blink signalling the cause of the failure (RED LED), it is
®
necessary to press the button again for no more than two seconds.

RECYCLE FUNCTION

The control box allows a recycle, i.e. complete repetition of the start-up programme, making up to
3 attempts, in the event the flame goes out during operation.
If the flame goes out again, this will cause the burner to lock out. If there is a new demand for heat during
the recycle, the 3 attempts are reset when the limit thermostat ( TL ) switches.

LOGGING OF BURNER OPERATING PARAMETERS

With this control box, data - i.e. the number of blocks that have occurred, the type of block that has occurred
(just the last one) and the oil valve opening operating time - can be logged even when there is no power supply.
That way, you can determine how much fuel has been consumed during operation.
Do the following to display the diagnostic:
Connect the kit supplied separately to the appropriate socket on the control box.
®
The information is read after the software program in the kit is booted.
