Good accuracy, easy installation

Comments about 20 K ohm NTC non-linear Temperature Wall Module:

PexSupply got this delivered to me relatively fast. The device is well manufactured. does not come with cable, but comes with a nice small screwdriver. Easily installs, and in operation, delivers decent accuracy. There is a bit of thermal momentum, so to speak, when the thermostat is correcting several degrees, as in recovery from economy mode in the morning. But, not a big deal. As expected, the wall temperature affects the measured temperature. It makes a difference in my case as I live in an apartment building, and there are hot pipes behind the wall. But that's not the devices fault.

WORKED!

This was easy to install. With a high distance like this, a 160 run of wire did not shift the indication. It's been reliable for several months in a church worship area.
