4.7.5 CONTROL BOX RESET
To carry out the control box reset, proceed as follows:
³
Hold the reset button down for between 1 and 2 seconds. If the burner does not restart, you must make sure
the limit point thermostat
(TL)
is closed.
³
If the control box reset button keeps flashing, reporting the cause of the malfunction (RED LED), you
must press the button again, holding it down for no more than 2 seconds.
Warning:
If the reset button is pressed for more than 2 seconds, the control box goes into visual diagnostic mode and
the indicator LED begins to blink (see CONTROL BOX VISUAL DIAGNOSTIC page 18).
4.7.6 RE-CYCLE FUNCTION
The control box allows re-cycling, i.e. the complete repetition of the starting programme, for 3 attempts maxi-
mum, in the event the flame goes out during operation.
If the flame goes out again (4
th
time), this will cause the burner to lock out. If there is a new demand for heat dur-
ing the recycle, the 3 attempts are reset when the limit thermostat
(TL)
switches.
4.7.7 LOGGING OF BURNER OPERATION PARAMETERS
With this control box, data - i.e. the number of lockouts that have occurred, the type of lockout 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.
To view these parameters, you will need to connect the software diagnostics kit, as described in section
(1.2) on page 2.
