Commissioning the heating system
The following actuators can be switched "manually"
Danger
Incorrectly connected actuators can cause dam-
age to the system.
During the actuator tests, check the respective
actuator carefully.
Danger
Activated charging devices (feed screw con-
veyor, screw conveyor, etc.) can cause block-
ages in the fuel discharge system during the
actuator test.
Activate charging devices only briefly.
!
Please note
The ignition element is damaged by overheat-
ing.
Always ensure that the combustion chamber
door and the covers on the boiler body are
closed during start-up and heating operation. If
the combustion chamber door or any covers are
open, the ignition element does not receive the
required air supply.
Note
Depending on the previous setting, other actuators will
be available.
Each term on the display is followed by the action of
the corresponding actuator, which will be carried out. If
not action or the wrong action appears, check the cor-
responding electrical connection.
Automatic overfill protection is disabled during the
actuator tests.
