If it has no low limit control, so is a 'cold start' boiler as many are today, then it needs no low limit. The single control with the dial would be a high limit (usually an L6006A) to prevent the boiler from getting too hot.
As you have more than one zone, the boiler water will rise to the high limit setting approximately, due to one zone, then another calling for heat repeatedly.
If you want the boiler to reise to temperatures as needed then
