Reversible liquid crystal thermo sticker
indicates the operating temperature of the
spot around the sticker. This temperature is indicative for the operating mode of the
pellet burner and the hydraulic losses of the flue gases, passing through the heating
appliance to the flue stack. The initial condition of the thermo-sticker is indicated with
black color of all thermo active segments. In case of temperature rise, the segments
are sequentially getting light colored, according to the temperature range of any
individual thermo-active segments. However, the increased temperature in this zone of
the burner is indicator for the requirement for planning of ash cleaning procedure of
the heating appliance and/or the chimney. At cooling down the main body of the
burner, the reversible sticker gets into its initial condition (all segments are dark)
