    We are replacing with a new controller, will update soon

    rtd reading

    Yes, I agree. I've done the same test on another controller and the reading is 77f. It is a controller issue, as I suspected all along. The second controller is slightly newer, may have something to do with it. I'll check a few others as time/project allows.

    rtd reading

    Yes I agree. Getting a schematic of the bridge system reading this will be difficult. The packages say "duct sensor 10k type II", we have used this type alot here, possibly 300. I have in the past tried this on several other locations, some have 70 some 77 and some way out at 60s. So I am...

    rtd reading

    The resistor is a 1% (gold) and has been tested on several meters to read 9.99-10.01k ohms. its accurate. the wire isnt an issue since we got the same temp reading at the controller and at location. The length is about 100 feet and its 18 guage, will check. i dont believe its the issue, its...

    rtd reading

    Since i have connected the resistor directly to the controller, with no extension wire, and have connected it at the location and got the same reading both times, I dont think the wire guage or length is an issue. It reads the same. Should a 10k resistor read 77 deg?

    rtd reading

    Thank you. I guess my basic question is should the controller readout be 70 (as it is) or should it be 77, with the 10k resistor connected?

    rtd reading

    Hello, so I'm having some issues with a few rtds reading in occupied spaces. Several local pocket temp sensors are reading 7 deg higher than the readout on our distech controller. These are 10k type II @77F, it says on the bags of all of these. So to troubleshoot, I took a 10k resistor and put...
