step

is the current program step number (00 - 99)

 

substep

is the current program substep (0-4)

 

TTT.Tis the setpoint temperature displayed to the nearest .1°C

 

HH

is hour(s) (00 - 99)

for ramp or hold

 

MM

is minute(s) (00 - 59)

for ramp or hold

 

NNN

is the next program step number (00 - 100) to execute

 

P

is the number of the probe (1 or 2) to use for control or...

Pis the special command indicator (values of 3 thru 7) (See 6.8 for details)

The simple graph at the right shows a typical ramp & hold scenario. In this example the user wants to ramp from 0° to 78° in 20 minutes and then hold 78° for the next 20 minutes. A single program step will accomplish both tasks.

The sample program step below will pass control to program step 6 when it has completed.
