:
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)
;
Irreversible liquid crystal thermo sticker
is indicator for at least one
event of overheating the pellet supply pipe of the main body of the burner.
This sticker changes its color irreversibly. Initially the color of this sticker
is white, at activation the sensing segment gets dark irreversibly;
