You also may switch the ETAMATIC to "Manual Control" with the terminals. By short-circuiting
the PT 100 signal (e.g. bridge terminal 19 and 20) the burner firing rate controller is switched
off. The fuel/air ratio controller then directly follows the input at the default firing rate input. The
display shows LE instead of HA.
NOTICE
Only use manual control while monitoring the system.
