A period of time to elapse before controller starts a firing, for example, in order to make use of off-peak power.
The rate of heating up or cooling down, usually expressed in number of degrees per hour, e.g. 150°C per hour. A Kiln firing to 600°C at 150°C per hour would take 4 hours.
Set Point/Target temperature
The temperature at whichthe controller changes the ramp rate, starts to soak or switches off. For example a program might fire at 100°C per hour to the first set point of 600°C then fire at 250°C per hour to top temperature of1120°C.
Soak or Dwell
The period of time that the kiln is held at a temperature in order to smooth out glazes or even out temperature in the kiln. Typically 15 to 20 minutes.
One part of the program, usually consisting of a ramp, a target temperature and a soak.
Output from a controller to operate an automatic damper, openingand closing it during the firing.
