Operation and Maintenance Manual - GB
If we are going to control the pump in the boiler circuit (recommended S14 = 12 or S14 = 13),
we must always connect the TK sensor.

displays the
current status of the conveyor
• Conveyor faults -
displays
information for the service engineer
• Spirals -
displays
the current status of the ignition spirals
• Spiral faults -
displays
information for the service engineer
• Reserve R -

TESTING menu
• Autotest
– This function is used for automatic testing of all the basic elements of the burner as the
fan, conveyor, ignition spirals, etc. The testing is carried out consecutively in 20-second intervals
so that the engineer can monitor the operation of individual devices. If this test is not sufficient,
individual devices can be run separately, namely with the use of the following functions.
CAUTION
– During testing the burner is put out of operation, therefore before the start of
testing always let the burner properly burn out
with the use the STOP command.
• Fan
- this function is used to test the operation of the fan
• Conveyor
- this function is used to test the operation of the conveyor
• Spiral 1
- this function is used to test the operation of the ignition spiral 1
• Spiral 2
- this function is used to test the operation of the ignition spiral 2
• Reserve R
– this function is used to test the switching device (relay) of the reserve output R
• Reserve R2
– this function is used to test the switching device (relay) of the reserve output R2
• Photocell
- used to test the photocell. Conduct the test by observing its sensitivity when it is
inserted in the burner or outside the burner in the natural light (never on the sun – will cause an
alarm).
