Single Offset 

If a constant offset is required across the temperature range, set the required “High Point” 
(

PNT.HI

) and “Low Point” (

PNT.LO

) to the required values (not the same), then set the “low 

Offset” (

OFS.LO

) and “High Offset” (

OFS.HI

) to the same value. 

 

Caution! - Do not make 

PNT.LO

 and 

PNT.HI

 the same value as the controller will 

not work correctly and could cause your furnace or oven to overheat. 

 

4.7 Holdback 

 
If the temperature ramp rate of the program is quicker than the furnace or oven can achieve, 
the program will wait until the temperature of the furnace or oven catches up. 
e.g. If a Holdback value of 10 is set and the program is set to ramp to a setpoint of 600°C, 
the program will reach 600°C, then go into an hold state; the hold indicator will light until the 
furnace or oven temperature reaches 590°C, the program will then continue to control 
again. 
The hold back will only apply once per Segment, therefore when control has been re-
established, the hold back will not apply again to that segment, even if the furnace or oven 
temperature go outside the hold back band.  
 
Holdback can only be accessed in supervisor level (level 2) by scrolling with the Scroll

until the display shows

 

H.BACK

 <

PROGRAM HOLD BACK

>: Use the Up 

S

 Down 

T

 to select the 

required Hold Back value. 
If a multi programmer is used, each program can have its own Holdback value assigned to 
it. 
 

Note:

 

When a Holdback is set, each segment used must have a Ramp Rate assigned 

to it, in order for it to be recognised by the program.

Creating a Program 

Programs can be created in level 1 or level 2 of the 3216 P1 and 3216P5.  Each program 
contains 8 Ramp/Dwell pairs. 
 

Note: 

A currently active program cannot be altered. Go into reset mode before starting to create or 
modify a program
