I have a RKC REX C-100 PID temperature controller from CHINA, they are a different
revision than the RKC REX C-100 PID temperature controller from JAPAN.
Do not throw out the Chinese double sided instruction sheet because the Initial
Setting parameter labels have the same names, but the parameter values are not the
same.
For example the LCK code to get to the Initial Setting parameter is 1000 not 0000.
The SL_1 input type parameter for 100 Ohm Platinum RTD is 1000 not 1100.
The parameter tables are closer to the CD-101 controller layout

than the C-100 JAPAN controller.

The initial setting parameter tables are two tables Cod 0000 and Cod 0001. In the
Cod 0001 table you can only see the decimal point setting parameter if you use the
100 Ohm Platinum RTD type Pt100.
(SL_1 set to 1000 and PGdP set to 0001 for 000.0 deg C display resolution.)
The PGdP parameter does not appear in the Cod 0001 table when set to the type K input
0000, so only 1 deg C display resolution is available.
Change the Cod value between 0000 and 0001 to scroll through the two tables. SL_2,
3, 8, 9, 10, and 11 are omitted like in the CD-101 table parameters.
Using the SL_2 to change deg C to deg F (0000-0001) did not work for me. Only deg C
display is available.
I have also found two different power options from the C-100 controllers from China.
Option 2 is a 220 VAC transformer and Option 1 is a 100 to 240 VAC switching power
supply which was not in the specification section or EBAY pictures of the Dual
Digital F/C PID Temperature Controller Control E12.
The unit works great, with two minor problems. No deg F display available, only deg
C. When using the included type K thermocouple, only 1 deg C resolution available
not 0.1 deg C.
