Abstract (en)

[origin: EP0872695A2] The control (4) operates the burner (2) by a turn-on command when a bottom threshold value for the temperature of the medium is undershot. The burner is switched off when the top threshold value is exceeded. A time-lag device (7) between the control and burner delays the control's switch-on command to the burner by a pre-set amount of time which is adjustable.
