Using of BioTec Plus boiler are consist of using of left part of the boiler (fuel: wood) and using of
right part of the boiler (fuel: wood pellets). On boiler control unit is necessary to choose which side
of the boiler will be used (which fuel will be used). Below is shown procedure for choosing boiler
side for work when is boiler turned off (working phase „OFF”).
PROCEDURE FOR CHOOSING BOILER SIDE FOR WORK (USED FUEL):
Example: Selecting wood pellets for active fuel (right side of the boiler).
Left and right side of the boiler have indicators (A and B) which shows which of these two side are
active (which fuel are choosen). Active side have green indicator, inactive side have red indicator
(red „x”). On figure above is example for switching from left side of the boiler to the right side of the
boiler (from wood to wood pellets). It’s necessary to press and hold for 3 seconds indicator on
inactive boiler side (figure 1, indicator B). On display will be displayed message „Do you want
choose wood pellets for active fuel?” (figure 2). Press „OK” button (figure 2). Now left side of the
boiler have red inactive indicator, right side of the boiler have green indicator of activity (figure 3.).

TAKING OVER
Note: Option „Taking over” is possible only from left side of the boiler (fuel: wood) to right
side of the boiler (fuel: wood pellets) (wood pellets taking over wood).
„Taking over” option is used for automatic switching operation from one fuel to another fuel.
Automatic switch is possible only from wood to wood pellets.
For use of „Taking over” option is neccesary to activate it (see „Activating „Taking over” option”).
„Taking over” option works on the way that when left part of the boiler (fuel: wood) runs out of the
fuel, right side of the boiler (fuel: wood pellets) automatic take over work activity and right side of
the boiler (fuel: wood pellets) continues with work.
ACTIVATING „TAKING OVER” OPTION
Activating „Taking over” option can be done on two ways:
a) through main menu (menu: WOOD(w), „Taking over” submenu)
b) through main screen by pressing boiler side status indicator
a) activating „Taking over” option through main menu
On main menu (menu: WOOD(w)) (see Point „8.1.4. Main menu”) choose submenu „4. Taking
over”, select „Pellet On” and confirm it by pressing „Confirm” button.
b) activating „Taking over” option through main screen (boiler side activity indicator)
Press green activity indicator on right boiler side (fuel: wood) and hold it for 3 seconds. On display
will be desplayed „Do you want to ENABLE „pellets take over?”. Confirm it by pressing „Confirm”
button.
Hold this button for 3s!
