Home display 

The first display of the controller screen, to which it returns when no 
keys are pressed. 

PID 

Proportional, Integral, Derivative: the control system used by the 
controller. 

Parameter 

A temperature or time value, or program action. 

Segment 

A program section in which a group of  parameters are set. 

Program 

A pre-set sequence of segments to control temperature changes 
and time periods. 

Measured 
temperature 

The actual temperature of the furnace or oven. 

Setpoint 
temperature (SP) 

The target temperature when operating as a controller. 

Program setpoint 
temperature (PSP) 

The target temperature as a program proceeds. 

Reset 

A single action by the operator to stop a program running and return 
to simple controller mode. 

Holdback 

Holdback can be used to prevent the PSP from running ahead of the 
actual heating or cooling. 

Ramp 

The Program Setpoint temperature rises or falls over a period of 
time. 

Rate  

The rate; in degrees per second, min or hour, of the Program 
Setpoint temperature rise or fall. 

Time  

A set time period for the Program Setpoint temperature to rise or fall. 

Step 

An immediate rise or fall in the Program Setpoint temperature. 

Dwell 

Time period during which the PSP is fixed. 

Wait 

The program waits until a selected external parameter has been 
met. 

Call 

Interrupts a program to run another program, then returns to 
continue 

End 

A segment type to end a program by either: Going into Reset and 
controlling to the SP; Dwelling at the last PSP value until Reset is 
pressed; SafeOp 

SafeOp 

Turns the power off. 

Element 

The heating device used in the furnace or oven. 

Thermocouple
