JLD-612 as a replacement what am I doing wrong?

[steve.j]

I am replacing a CAL9900 Temp controller on my Glue pot to control the hose and gun appllicator. In this case I am installing two (2) JLD 612 controllers, one for the hose and one for the gun, everything is wired but I cannot get a temperature reading. The sensors are two wire rtd and I've tried all variations of rtd choises in the "inty" menu. I get only "EEEE.E" If I change to any thermocouple version I get a display of 68-72f in a room that is 66 and when heat is applied there is no change, just an oscillation between 68-72f. Using an ohm meter, I read 110ohm on the sensor @66f. What am I doing wrong?

Try hooking one lead of the RTD to pin 8, the other to pin 9 and jumper bare wire from 9 to 10. Also, is the RTD a Pt100 device?

Thank you, that jumper is the solution. I am using a PT100 rtd and now that I look at the drawing in the instruction manual it seems clear and I feel like an idiot, but an appreciative one no less. Again, Thankyou Richiem, problem solved.

Terrific! That's why forums like this are important.
