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. The burner anti-cycling time is only active for
the heating mode. Hot water handling mode during a burner
anti-cycling time does not affect the time function element.
