Note on program no. 1:
⇒ Preset program no. 1, “Initial firing”, is used for:
- the initial firing of the kiln after commissioning,
- after replacing new heating elements (oxidation firing),
- and the initial firing of new furniture material (stilts and batts)
⇒ When using program no. 1, “Initial firing”, the supply and exhaust air openings of the kiln must be open.
Please also consult the kiln instruction manual.
5.3.2. General information about firing programs
• The 4 preset controller programs are simple sample programs for biscuit, earthenware and stoneware firing.
These programs must be checked before firing to allow the firing temperature, heating rates and soak times
to be adapted to the materials used.
• A total of up to 32 program locations are available in the controller for individual program assignment. The 4
preset programs can also be freely replaced with personally designed programs.
• The variety of ceramic bodies, engobes, glazes and decorative colours, as well as different types, sizes and
performances of the kilns used, and individual furniture set assemblies, types and quantities of products to be
fired, make it difficult to make generally applicable recommendations.
• We advise against using uncontrolled full-power heating ramps (FULL/SKIP) to protect heating elements and
the kiln from unnecessary wear and to allow for repeatable firing results.
