I used a Johnson Controls A419ABC-1C Electronic Temp Controller for mine and it came with the probe. I put a hand/auto/off switch on mine so i can force or kill, if i need to over-ride setpoints. Dwyer makes very nice controls, but i am pretty sure that a probe won't be stock with the switch you are looking at using- you will have to buy as an accessory. Buy the one from dwyer (they should be listed under options in a manual or submittal), because (even though you would think they all would be) -not all probes are interchangeable. Good Luck!
