Problem description Possible cause / solution
Self-test
The air control lever only moves to the right and
stays there.
• No power between actuator motor and actuating lever, driver pin (star) has wandered out of
position.
• Link lever clamps on the primary air flap are
dragging on the ground and getting jammed.
• Check door contact and its setting.
Self-test
Air control lever first moves to the left, then to the
right, where it then stops moving.
• On the motor connector on the control system, swap over the red and white core leads
(stoves) or the brown and grey core leads (fire
place inserts).
In operation
The air lever moves too quickly back to the left in
the closed position.
• Does the current parameter set match the
appliance?
• Check the flue gas temperature display: are the
values displayed plausible?
• Check wiring of flue gas sensor for impermissible extension with copper cable or similar.
• Clean the water heat exchanger if fitted.
• Check draught conditions
• Check leak tightness of the appliance (viewing
panes, door, ash pan etc.).
In operation
Air control lever does not move to the right in the
100% closed position after the firebox door has
been opened.
• Check that the "Door open" message appears.
• Air control lever: Mechanism movement is
impaired. Loosen it up.
• Clean and degrease the rotary slide disks
• Door contact switch: Check function of door
contact switch.
• Check the wiring of the door contact switch to
the terminal box
• Check to ensure that the permanent magnet
approaches < 10 mm at the switch.
In operation
The air control lever does not close all the way.
• Make the mechanics tight but functional
• Clean and degrease the rotary vane discs
• Check the parameter setting: does the current
parameter set match the device?
• Check the air control lever mechanics for
looseness
12. GUIDE
The S-Thermatik NEO burnup controller detects the most significant errors
automatically and displays these in the form of clear text messages.
Motor errors are detected whenever the motor fails to move in response
to a movement command. Errors on the flue gas sector are detected by an
algorithm in the software. In both cases, the fire area must not be put
into operation until the error has been remedied.
First check if an error message appears on the display. Consult this advice
guide to assist you with this. If the problem cannot be resolved in this way,
please contact your dealer or stove fitter.
Problem description Possible cause / solution
Error message
Motor circuit open or motor error
Check that the motor cable is plugged into the
correct bushing.
• Check the motor cable.
NOTE: To reset the error, isolate the control unit
from its mains power supply briefly OR, in the User
menu, first select and save Manual mode then
select and save Automatic mode.
Error message
TC open or short to ground
• Check that the motor cable is plugged into the
correct bushing.
• Check the motor cable.
NOTE: The error reset is automatic whenever an
intact sensor is connected up
Door open - message:
The "Door open" message does not disappear after
the fire door has been closed
• Check door contact
• Check that the permanent magnet is still positioned above the door switch.
• Check the magnet for breakages
• Check settings in the door switch menu (NO
/ NC).
Overheated message
During the burnup, the message "Overheated"
appears
• Reduce the wood feed quantity.
• Check that the appliance setting has the correct set of parameters. The reset process is
automatic as the combustion chamber cools
down.
