Slow down
In “Slow down” mode, the burner power is reduced step-by-step to 1 level after boiler thermostat is
switched OFF. This mode can be used only is systems with high and stable power demand. Using “Slow
down” mode in systems with low thermal inertia or unstable power demand, there will be risk of system
overheating. The “Slow down” mode is recommended to use together with “Hold flame”. “Slow down”
mode can be switched ON or OFF from main menu.
Figure 29 Slow down mode
Hold Flame
“Hold flame” mode purpose is to avoid burner start-up procedures every time when burner is switched
on from boiler thermostat. In “Hold flame” mode, minimum fuel and air amount is delivered into burning
chamber. “Hold flame” mode can be switched from burner main menu to ON, OFF or AUTO. When “Hold
flame” is selected as AUTO then burner will turn the mode on or off depending of “Waiting” time:

If “Waiting” (time between “End blow” and thermostat ON) is shorter then Par 11, then “Hold
flame” mode is switched on.

If “Hold flame” is longer than Par 12, hold flame mode is turned off
“Hold flame” is also used as intermediate state before cleaning or after “Slow down”
