WTS-WP-4-12 sensor is dropping temp when heated
[Updated Nov '19]
From a quick look at the part number I see that its a 1k Pt sensor, the early rev hardware doesn’t support 1k Pt sensors but the latest model has an option module which
adds 1k Pt sensors to our usual universal input signal types: 10V, 4-20ma, 10k thermistor, dry contact and so on. The added cost is $5 to $10 depending on the number of inputs. If your hardware supports this signal type the ranges 35 and 36 will show up in black. In my screen shot here the module isn’t present so they are greyed out and not selectable.
