Many customers ask how to set up a PID temperature controller for their furnaces. The following is an example of setting a PID temperature control program with a 6-segment profile, hope this can help you. If you prefer to video tutorial, please find it at the end of this article.

For a complicated temperature control profile, we strongly suggest you make the drawing as Fig.1 then make a form as table 1 to list all data in every segment.

Fig. 1 is the temperature profile that we would like to set.

According to this profile, you shall list all segments in the following Table

Segment #	Symbol in Panel	Data to be In-put	Meaning in the program
1	C 01	0 (℃)	Initial Temperature
2	t 01	30 (min.)	Ramping time from 0 – 300℃ Average Heating rate is 10℃ /min
3	C 02	300 (℃)	Target temperature value to first heating stage ( 300℃ )
4	t 02	10 (min.)	Soaring time at 300 oC stage
5	C 03	300 (℃)	Temperature value at the heating flat
6	t 03	130 (min.)	Second Heating time from 300 -1600℃ The average heating rate is 10℃ /min
7	C 04	1600 (℃)	Target temperature value to peak heating stage ( 1600℃ )
8	t 04	30 (min.)	Soaring time at 1600 oC stage
9	C 05	1600 (℃)	Temperature value at peak heating flat
10	t 05	100 (min.)	Cooling time to 500℃ The cooling rate is 11℃ /min
11	C 06	500 (℃)	Target temperature to be cooled ( 500℃)
12	t 06	-121	Program end, Out-put power off. Furnace cooling down naturally (t 06 = -121 is an order to stop running.

Using 4 keys of to enter data listed in the above table into the controller separately, then, you finish one temperature control program finish Please be noted that “ t xx “ is the time value for the XX segment. It can be set from 1- 9999 minutes. However, if “t xx “is set as the following values, it can be as a special order. These orders only can be used in complicated multi-temperature profile programs.
