Start-up with long pre-ignition (t3) and supervised air damper control. Air pressure
supervision from the start to the controlled shutdown. No load control. Necessary flame
safeguards: type LAE10... with selenium photocell detector RAR...
Air damper control, detailed
In case of burners without air damper or with an air damper not controlled by the control unit, terminals 20, 21 and
22 must be interconnected; the path 18-c1-21 of the circuit, however, must be omitted!
* Connection is dropped with the use of an air pressure monitor LP
