Burner anti-cycling time
8.6.1
Setting the burner anti-cycling time
To prevent frequent switching on and off of the burner and
thus prevent energy losses, an electronic restart lockout
is activated for a specific period each time the burner is
switched off. You can adjust the burner anti-cycling time to
the conditions of the heating installation. The burner anti-
cycling time is only active for the heating mode. You can set
the maximum burner anti-cycling time under
D.002
(default
setting: 20 min.). The effective burner anti-cycling times with
respect to the target flow temperature and the maximum set
burner anti-cycling time can be found in the following table:
