Yeah, it has a heat exchanger in the HLT and the thermal mass of the grain will slow any temp fluctuations a little. (Very little.) I'll just turn the pump on when needed.
You're likely to find that the easiest way to manage a HERMS system is to leave the pump running and tweak the temp of the HLT. I mash in a cooler, not a pot, but run my HERMS for the full mash cycle. I keep the temp in the HLT 3-4 degree higher than my desired mash temp and keep an eye on the temp of the wort that's flowing out of the coil. I find that if I keep the HLT burner on at it's absolute minimum it puts just enough heat back into the pot to keep it at that temp.
Running the pump full-time has the added benefit that when it comes time to transfer to the boil kettle the mash bed is so well set that you get crystal clear wort right from the start.
