[dsg-svt] Chiller Temperature

[Brian Eng]

Here's something cheap that seems like it should work?

They're fairly cheap and still have a voltage output so it shouldn't be to hard to integrate with the existing system. Just need to order that plus the connector.

And actual RTD would have more range, but wouldn't be as straight forward to get into the controls system.
