The probe should go into the HLT water. If you put it at the outlet of the coil the HLT water will get too hot and will take forever to cool down. Start with the setpoint a bit higher than needed, then reduce to desired setpoint as the whole system comes up to temp.

Recipes 

I would have two probes. Have one in the hlt to control the temperature of the water and another on the output of the HERMS coil to measure the temperature of the wort. That way you can adjust the hlt temperature as needed.
