It is understandable that the plumbers were totally clueless about how to wire controls for their purpose. A decade ago a Honeywell middle manager was instrumental in stopping the only boiler control training program that gave the full story on how to wire multizone with hot water among all the other wiring methods for boilers.

Plumbers get into the field to be plumbers, then discover they are suddenly boiler experts and then discover they have to be wiring experts. It only goes so far.

The L8124A control is not the proper one for the job and the blue wire on the face of the control has to be pulled and capped to prevent the boiler from maintaining a low water temperature.

This removal of the low limit function makes it function more like an 8148A.

There is no hot water zone priority function in your wiring setup now. You can add that feature by using a Taco circulator zoning control board or equivalent.
