Recommended Settings to Run WM Boiler for Indirect storage tank during summer

Thanks in advance.

We had a new Weil-Mclain CGa-4 cast iron boiler with the Aqua-Plus 45 indirect water heater installed in the fall which ran great throughout the winter. Everything worked as expected with the indirect on a priority zone for DHW so we always had enough hot water. The boiler temperature was set to 180 degrees for our copper-finned baseboard heat and the indirect set at 140 to help avoid any potential for Legionella disease with a mixing valve set at 120.

Now that it is summer should we keep the boiler set at 180, or does it make sense to reduce it, or does it just make sense to leave it as is since talking pennies and better for boiler to be set at 180 all year round?

Also, there is an Economy Adjust setting on the Weil-Mclain boiler which delays the firing of the boiler to determine if the call for heat can be satisfied by existing boiler water temperature. Upon inspection, it was set to "Min" from the onset but the manual indicates the preferred setting is "Max". Not sure if this adds any value in changing this?

Any perspectives would be greatly appreciated.
