Temperature for 1st switching point: Tmp1
The kiln heats up at the previously set heating rate (Rmp1) until reaching the tem-
perature set for the 1st switching point. By default, the temperature is entered in
degrees Celsius per hour.

Cooling or end of program: Rmp3
At the end of the dwell time, the kiln cools down either controlled (e.g. 200°C/h) or
uncontrolled (= SKIP). At 150 °C, the controller stops the temperature control and
the display shows "End" to indicate the end of firing.

Saving a program
The TC 304 automatically saves all the variable values of the firing curve.
The control unit stops the processing of the program if no values have been entered
for 30 seconds. The display indicates the room temperature.
As an alternative, press the "Start/Stop" key to start the desired program imme-
diately or use the mains switch to turn the control unit off.
Values that have been changed are saved automatically.
Appendix A: TC 304 Error and Event Messages
Error and event messages
The controller indicates particular events such as power failure, sensor malfunctions
or kiln errors and processes them accordingly.
The event codes are:
E-CODE A = Operational and controller errors
E-CODE B = Errors resulting from power failure
E-CODE C = Internal errors
E-CODE D = Hardware errors
The list below shows possible event messages and their meaning.
