Burner Control Unit Features:
Post ignition (during safety time)
The spark ignition is present during all safety time.
Adjustable post purge
The Post-purge is a function that maintains air ventilation even after the burner is switched off. Post-purge time can be set to a maximum of 6 minutes.
This function can be activated and set in a very easy way by pressing repeatedly the reset button; after 5 seconds the control box automatically shows the minutes set by the red LED flashing (1 pulse = post-ventilation for 1 minute).
If during post-purge there is a new request for heat, it is halted and a new operating cycle starts.
The control box leaves the factory with the setting 0 minutes (no post-ventilation).
Remote lock-out reset
The “Remote lock-out reset” is a function that allows to reset the control-box operation from a remote position. In the burner packages will be included a particular connector to remote the reset signal.
The maximum length of connection must be 20 m.
