7. Temperature program selector
Temperature program selector, which is also called a driver, is a unit of two
cooperating modules – a temperature adjuster and an electronic clock. The main feature
which distinguishes it from an ordinary temperature adjuster is a function of temperature
increase control in a specific time.

Glossary
program selector - (driver) – temperature adjuster with the control of temperature
increase, its holding and decrease in the furnace;
temperature increase – monitored temperature increase (heating) in the furnace
chamber, its value is defined with the use of the unit: [
o
C/min], it is illustrated with the
rising line;
cooling – a kind of temperature increase, but in the opposite direction, its value is
defined with the unit:
o
C/min, it is illustrated with the falling line;
temperature holding – holding the fixed temperature which has been reached in the
previous section, it is defined with the time unit: [min], it is illustrated with a straight
line;
programme – a list of subsequent sections which constitute the instructions concerning
the way of heating, set by the founder in the program selector;
section – a part of programme describing the performance of the program selector in a
given time;
delay – a function of the program selector which enables initiating the previously saved
programme with the time delay;
temperature priority – a function of the program selector which operates in the
background of each section, which is aimed at stopping the count of time in the section
when the furnace chamber is under-heated in the ±5
o
C band;
restoring of power supply – a function of the program selector that enables the
continuation of the burn out process after the power supply is restored in the situation
when power supply was cut off;
