Yes you are correct, the tec module will run based on the timing source dt. 1MHz clock gives you 1uS dt. 5000 ticks x 1uS gives you the 5mS. If you need the engine to run at 5mS, but the tec module to run slower, there is an option to decimate the module. This will make it run every nth iteration. This will allow you to run the engine at the speed you require but only send the data at a decimated rate. Decimation is good to slow down coms or for datalogging at a slower rate.
