1.2 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 necessary 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
In main menu (menu: WOOD(w)) (see Point „1.0 Main menu” page 6) choose submenu „4. Taking
over”, select:
- "Pellet ON" and confirm by pressing the "Confirm" button, if we want the right side of the boiler
(fuel: wood pellets) to automatically take over the operation and resume operation immediately
depending on the set "p.Max. Boiler temp." and Schedule (if the boiler Schedule is enable the
boiler will only work when the boiler Schedule permits).
or
- "Pellet OFF" and confirm by pressing the "Confirm" button (this can only be selected if active
Schedule and / or configured Internet supervision and / or Cm GSM is configured), if we want the
right side of the boiler (fuel: wooden pellets) ) automatically takes over, but only starts working
when switch-on Schedule and / or internet supervision and / or Cm GSM activates.
