Conventional Propane Boiler

Hi
I have a low mass Biasi conventional propane boiler. It doesn’t have any special controls so need help with what I currently have. Right now it’s set up as a cold start boiler which Biasi recommends. Here’s how it works - Thermostat calls for heat and boiler fires, water temperature reaches a certain temperature and aquastat tells circulator pump to kick on, boiler keeps firing until thermostat is satisfied and the burner shuts off. Circulator pump runs until water temperature cools. Aquastat that controls the circulator has a differential of 30. What should I set the water temperature at on the aquastat to start circulating water? Keep in mind it’s a cold start boiler.
Thanks
